Homicide by Martin Daly and Margo Wilson

“Homicide is really interesting from an experimental perspective, because the data is so good. You can argue about whether somebody is abused or whether somebody is angry, or whether somebody is lying to you. But when you’ve got a murder, you’ve got a body; this definitely happened. And the police have got an incentive to find out who did it. So you’ve got really, really good data. This book so careful: the care they take over their data, their care about comparing the theories, it’s breathtaking. And deserves to be popular.” Chris Paley , Science Writer

Principles of Psychology by William James

“A wonderful summary of what was known and what questions were being asked at the dawn of psychology as a science in the 19th century. James is widely mis-cited and misunderstood as someone who advocated for a classical, common sense view of emotion. The irony is that he advocated for just the opposite.” Lisa Feldman Barrett , Psychologist

The Language Instinct by Steven Pinker

“The types of arguments that you’ve got to make in evolutionary psychology, Steven Pinker made them and made them brilliantly. You’ve got to break down people’s intuition that they already know how they do what they do—use language in his case—and they already know what it’s for, and how it works. It’s a wonderful book, both for the way it’s written, for the details, and for offering a background to evolutionary psychology.” Chris Paley , Science Writer

25 best psychology books to read in 2024.

Have you ever found yourself trying to work out what mental processes lead humans to do what we do? Thanks to the internet, even in isolation we have a continual stream of information about what people are doing — and with this uniquely modern view of the world around us, we have more fodder than ever to think: “Hmm, I wonder why we do this or that?”

As a human, it’s natural to want to understand these things — not only about others, but also about yourself. In this post, we’ve put together a list of the 25 best psychology books you’ll definitely want to read to pursue that understanding! Whether you’re a beginner with a newfound interest in psychology or a seasoned psychology expert looking to branch out, we’ve got you covered.

1. The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom by Jonathan Haidt

A professor of social psychology, Jonathan Haidt wrote The Happiness Hypothesis as an accessible vessel for his research into moral foundations theory. In this book, Haidt takes the ancient wisdom, or “Great Ideas”, of historical thinkers — like Buddha, Plato, and even Jesus — and reveals their applications in light of contemporary psychological findings.

Haidt first describes the basic meanings of ancient lessons on happiness, virtue, and personal fulfillment. This leads into what Haidt extracted from these findings to develop his own “10 Great Ideas” about happiness and connect them to modern living. After all, while ancient wisdom is tried-and-tested, it’s essential to update old methods to match modern-day life — Plato, Jesus, and Buddha never spent hours doomscrolling or procrastinating on Instagram, for example.

2. Influence : The Psychology of Persuasion (New and Expanded) by PhD Robert B. Cialdini

Influence, New and Expanded is Dr. Robert B. Cialdini’s 2021 republication of his one of his acclaimed bestselling psychology books Influence (first published in 1984) — complete with new research, examples, and insights, especially regarding the age of the internet. Backed up by his 35 years of scientific research, Cialdini describes seven practicable principles of influence you can use in your everyday life (with the newest edition being “Unity”). 

Each of the seven principles has a dedicated chapter to describe how it functions, where it’s most applicable, and — most importantly — how you apply it in your own life. If you’re looking for a book on psychology to help you learn more about the art of ethical persuasion in a modern context — and how to see through other people’s deceitful attempts — then this is the book for you.

3. Mistakes Were Made (but Not by Me) Third Edition: Why We Justify Foolish Beliefs, Bad Decisions, and Hurtful Acts by Carol Tavris

Ever been curious what causes people to deny vaccines, join cults, or engage in extremist behavior? The next entry on this list might clarify some of these seemingly illogical decisions:  in Mistakes Were Made, Carol Tavris and Elliot Aronson discuss the systematic mental patterns which feed into development and radicalization of human beliefs. These include cognitive dissonance, confirmation bias, and positive feedback loops, among others.

To further explain how people’s attitudes can become so polarized, Tavris and Aronson walk readers through the effects of these mental patterns on people in various real-life cases and controversies. With its many compelling links to real-life events, this book is the perfect read for psychology and politics readers alike.

4. Upstream: How to Solve Problems Before They Happen by Dan Heath

Life can feel like we’re constantly sprinting to put out fires as they arise. But of course, endlessly reacting to problems without a second to breathe and prepare for the next is pretty exhausting. Dan Heath’s Upstream is his solution to breaking that cycle of reaction and starting to prevent problems before they start. 

This begins with knowing the psychological forces that cause it. For example, one force that Heath attributes as a large factor is “problem blindness” — when a problem becomes so persistent that you start to register it as “normal” and therefore stop “seeing” it (or, naturally, trying to fix it). Heath shows how to step up and bolster your defenses against such problems by using real-life cases of individual thinkers, businesses, and even whole institutions that overcame their own. Thankfully, the uniting factor among these case studies is simple: all they had to do was change their mindset.

5. The School of Life: An Emotional Education by Alain de Botton

Many of us spend over a decade in school and, regardless of academic success, emerge feeling like something is missing. Sure, you can do complex algebra or give me an in-depth analysis of the symbolism of triads in Shakespeare — but can you navigate a workplace? Can you endure failure? Do you understand yourself? Whether you’re about to graduate or have been done with high school for years, you’ve probably found yourself wondering these things. 

Aptly titled, The School of Life is Alain de Botton’s answer to questions like these — with the express aim of equipping people with the tools and self-knowledge to thrive in the modern world. From increasing your productivity at work to handling the dilemmas of interpersonal relationships, there’s a chapter for everything you need in The School of Life. This emotional education is sure to help you to develop resilience to life’s dilemmas and become a maven of emotional intelligence.

6. Noise: A Flaw in Human Judgement by Daniel Kahneman, Olivier Sibony, and Cass R. Sunstein

You may recognize authors Daniel Kahneman and Cass R. Sunstein from their respective bestsellers, Thinking, Fast and Slow and Nudge (or from a Reedsy Discovery post !). In a similar vein, Noise tackles the topic of variability in judgements and how we’re influenced by external factors. The overarching conclusion in Noise is that the majority of our decisions are unconsciously affected by the noise at different times and places.

The authors combine their scholarly expertise with additional research to deliver this in-depth guide outlining what we already know and their new theories about noise. For those interested in why we make decisions, this is one of the best psychology books to strengthen your understanding of the extraneous factors that can shape or bias decision-making, how to minimize those factors, and improve your thinking.

7. The Lucifer Effect: Understanding How Good People Turn Evil by Philip G. Zimbardo

The Lucifer Effect is Professor Philip Zimbardo’s first detailed account of his infamous Stanford Prison Experiment and the conclusions he took from it. The Stanford Prison Experiment was Zimbardo’s 1971 study looking into the effects of different situational factors on conformity by putting college student volunteers into a fake prison environment for -2 weeks. Without giving too much away, the experiment ran into some serious roadblocks that meant it had to be discontinued after only six days. (The controversy was such that there was even a mostly-accurate movie dramatization released in 2015!) 

Zimbardo’s thoughts on the experiment are interesting not only because he conducted it, but because he was a part of it, acting as the prison warden — which, needless to say, has serious ethical connotations. The following chapters discuss the study’s effect on the decades of subsequent research into psychological and social variables that cause “average” people to commit immoral acts — making it one of the most influential books on psychology you can pick up today. Most people with an interest in psychology might have an idea of the original experiment, but the research afterwards should definitely not be overlooked!

8. The Psychopath Test: A Journey Through the Madness Industry by Jon Ronson

Put simply, The Psychopath Test takes us through the modern-day mental health system, asking us to think more deeply about whom it labels “psychopathic”. Jon Ronson starts with a man who faked madness to escape a prison sentence, his method being to act charming, glib, and well-presented in contrast to other patients in the psychiatric hospital. Ronson takes these alleged tell-tale signs of psychopathy and applies them to people in other walks of life, making the startling discovery that psychopaths appear everywhere. 

This is where the doors to the so-called “industry of madness” are truly flung open. How many of our most influential CEOs, researchers, and world leaders are psychopaths? Can any good come of our newfound access to the best psychology books or theories if they facilitate diagnoses of strangers based on their “maddest” parts? If these questions interest you, pick up The Psychopath Test  and see what you think.

9. Games People Play: The Psychology of Human Relationships by Eric Berne

We’ve mostly talked about complex mental health issues so far in this post—but maybe you want to know about the psychology behind our most basic social interactions. If so, Eric Berne’s description of functional and dysfunctional social interactions in Games People Play will be right up your alley. Berne claims that we play “social games” all of the time, be that power games against authority, sexual games, marital games, or competitive games within friendships. 

Berne divulges the types of mind games that everyone can fall victim to indulging: in status contests, the game becomes a back and forth game of “I know better”, and couples are prone to playing mental games claiming each is holding the other back. Berne doesn’t just name these interactions, but he also exposes the meaning behind them as unconscious ploys and maneuvers that rule our lives. It’s these creatively poised insights that make this book on psychology an influential and striking bestseller.

10. The Body Keeps the Score: Mind, Brain and Body in the Transformation of Trauma by Bessel Van Der Kolk

Described as “the Bible of trauma” for struggling readers, The Body Keeps the Score is the culmination of Dr Bessel Van Der Kolk’s entire career. One of the world’s leading experts on traumatic stress, Van Der Kolk highlights the clear effects that trauma has on literally reshaping the body and brain. Drawing on his status as an active therapist, continually learning from what works for his patients best, Van Der Kolk delivers a wonderfully personal yet analytic approach to trauma recovery. Considering the frustrating physical effects of trauma related by his patients, Van Der Kolk suggests a fresh paradigm for treatment. 

The ideological heart of this method is to make it safe for trauma survivors to inhabit their own bodies by moving away from the “standard” combination of talking therapies or drug therapies and instead using a new approach that heals the mind, brain, and body. One size never fits all, but Van Der Kolk suggests that therapeutic interventions like neurofeedback, theater, meditation, play, or yoga may play a larger part than first thought in healing. The Body Keeps the Score provides a unique perspective on trauma and recovery relayed in a compassionate yet truthful voice, making it accessible to readers of all levels.

11. The Comfort Book by Matt Haig

Ever just really felt like you needed a hug? The Comfort Book answers that craving: it is a warm and personal hug in the form of a book — something even the best psychology books haven't focused on before. If you’re looking for a guide to self-love, contentment, and emotional strength, then Matt Haig’s reflections on the conflicting feelings that come with being alive are for you.

The essence of this book is that many of our best and clearest revelations are made when at our lowest — but we also shouldn’t have to figure everything out ourselves, especially when we’re suffering. Haig’s reflections are built on what he’s learned in hard times, with the hope that they can get you through similar situations. It’s a great comfort to know that you’re not the only one that’s dealt with something hard, and Haig understands that. Drawing on maxims, meditations, and inspirational lives of others, he aims to nurture your inner strength and deliver advice like a wise, commiserative old friend.

12. The Oracle of Night: The History and Science of Dreams by Sidarta Ribeiro

What really makes a dream, why do we have them, and how do they affect us? Sidarta Ribeiro takes these questions and uses them as a springboard for his completely fresh and enthralling study of dreams, tracing them all the way back to our ancient ancestors. It’s in the earliest cave paintings that Ribeiro finds the first traces of human dreams and begins unlocking revolutionary conclusions about the role of dreams in human evolution. 

Some will also know that contemporary neuroscience and psychology have uncovered many findings about dreams, such as their role in healing trauma or in consolidating what we learned in the day prior. The Oracle of Night then explains Ribeiro’s advancements on these topics: the role of dreaming in memory recall and transformation, and, startlingly, their oracular nature as confirmed by new research — making this a great book club book to ignite a conversation! Ribeiro combines his absolute authority on the topic with a clear, compelling writing style to make this book a page-turner from the first page to the last.

13. Everyday Vitality: Turning Stress into Strength by Samantha Boardman

Psychiatrist Samantha Boardman believes that an essential factor in healthy aging and overall well-being is a sense of vitality. Which is to say: knowing that you’re up to a task both physically and mentally. This belief is the jumping-off point for Everyday Vitality, a book full of strategies for cultivating vitality by focusing on improving a little every day, instead of reacting to fix what’s wrong as it arises. 

While vitality wellness is often associated with managing aging, Boardman posits that vitality can help all of us no matter our age. Whether you’re eighteen or eighty, you may recall times you’ve felt mentally exhausted from the constant barrage of media every day, or physically drained after a long day at a desk. Boardman explains three routes to better vitality for everyone: meaningfully connecting with others, taking on experiences that push your limits, and contributing to something beyond just you. If you want to cultivate your own wellness, why not pick up this book and discuss it with someone you love?

14. Survival of the Friendliest: Understanding Our Origins and Rediscovering Our Common Humanity by Brian Hare and Vanessa Woods

Humanity’s success as a species has developed in leaps and bounds during our relatively short time on Earth. Many people have hypothesized what might be the cause of these advancements: is it our strength, intellect, curiosity, or something else completely? Authors — and husband-and-wife duo — Brian Hare and Vanessa Woods believe in the latter, making the case in this book that humanity’s progression is actually because of our “friendliness”. 

Combining their respective expertise in cognitive neuroscience, research science, and journalism, Hare and Wood have come up with a theory about this evolutionary friendliness. The theory is elegantly termed “self-domestication” — a remarkable propensity to coordinate and communicate with others. Instead of coveting our individual successes, we often share them with others to help advance and protect each other. This capability, Hare and Wood argue, has allowed us to achieve the impressive cultural and technical marvels that we’ve culminated today. However, this friendliness may come at a cost: when threats to those we love become a target for our worst instincts, our evolutionary propensity for bond-making may be a double-edged sword.

15. Blink: The Power of Thinking Without Thinking by Malcolm Gladwell

In Blink, critically acclaimed author and journalist Malcolm Gladwell hopes to revolutionize your understanding of how you (and others) think. Why, for example, are some people exceptionally fast decision-makers, when others choke under pressure? Why does “following your gut” work perfectly for some, while others fall short? And do situational variables like our immediate surroundings affect our abilities to make these decisions?

Gladwell posits that a key factor towards people’s ability to make better decisions is “thin-slicing”: the unconscious ability to analyze patterns in scenarios based on brief flashes of experience, and come to a conclusion based on that knowledge. Gladwell draws on real-life examples to illustrate these ideas: from a psychologist who could predict whether a marriage would last from just a brief interaction with the couple, to antiquities experts who only need to glance at an object to tell it’s a fake. Put simply, Blink proves that the main difference between a good and a bad decision-maker is their mastery of “thin-slicing.” Can you learn to do it, too?

16. The Paradox of Choice: Why More Is Less by Barry Schwartz

Have you ever walked into a clothing store and found yourself overwhelmed by choices among different shirts, skirts, or jeans, all of which look eerily similar? Not to mention the stress of weaving through other shoppers, worrying about prices, and working out your size. Barry Schwartz believes that this abundance of choices to make “no longer liberates, but debilitates” shoppers with consumer anxiety. The solution? Eliminating consumer choices (within reason).

Of course, Schwartz acknowledges that autonomy and freedom of choice are still critical to our well-being. It’s just that, while modern Americans may technically have more choice than ever before, they are no longer benefiting from it psychologically. The Paradox of Choice neatly establishes the psychology behind why choice overload makes us suffer — constant comparison, opportunity hunting, and buyer’s remorse, for example — and how to avoid consumer anxiety in the first place.

17. Explaining Humans: What Science Can Teach Us about Life, Love and Relationships by Camilla Pang

Explaining Humans is an intriguing in-depth exploration of the complexities of human behavior, as explained by hard science. Diagnosed with Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD) at an early age, author and scientist Dr Camilla Pang struggled to untangle the mess of the world around her — even asking her mother if she could find an instruction manual for humans. When she found that not even the best psychology books of the time provided such a manual, the only solution was to write her own. 

Backed up with copious amounts of scientific research and her own hard-won expertise, this book on psychology examines obscure social customs, what it means to be human in different cultures, and where proteins and molecular chemistry fit into all of this. What does it mean to understand someone? How do we recognize people’s motivations or expressions, and what dictates them to begin with? Whether this all feels foreign or far too familiar to you, Pang is sure to deliver some surprises.

18. Rationality: What It Is, Why It Seems Scarce, Why It Matters by Steven Pinker

The goal of Rationality is to make you more rational and help you understand why there is so much irrationality in the world. You may think that sounds pretty lofty, but try reading author and cognitive psychologist Steven Pinker’s analysis before making concrete judgements! 

Pinker rejects the cliché idea that humans are an irrational species — how could any species discover and achieve so much without being inherently rational? Despite this, we live in a dichotic age of rationality vs. intense irrationality. Pinker’s explanation is that humans tend to think within the context of the low-tech settings in which we spend the majority of our lives. As a result, we don’t take advantage of the tools that our best thinkers discovered previously: critical thinking, logic, probability, correlation vs. causation, and ways to update our beliefs individually are not a part of our education. Fortunately, you can find these tools (and analyses of the crippling effects of irrationality) presented clearly and with good humor in Rationality !

19. Rapport: The Four Ways to Read People by Emily and Laurence Alison

We’ve all had to interact with difficult people before, whether that’s an annoying customer, a high-maintenance friend, or even a demanding stranger on the train. But imagine you had to deal with some of the most difficult people possible, managing extremely high-stress interactions: criminal interrogations. These interactions are a specialty of forensic psychologists Emily and Laurence Alison: they advise and train police, security companies, and even secret services on how to maneuver interviews with dangerous suspects. 

After experiences over the past thirty years that the “average” person could only imagine, the author duo have developed a revolutionary model for interpersonal communication. According to them, every interaction follows one of four types: Control (the lion), Capitulate (the mouse), Confront (the Tyrannosaur) and Co-operate (the monkey). It might sound abstract now, but once you’ve been taken through these types in Rapport, you’ll understand why they’re so praised. Learn to understand and apply them to your own goals and you can shape any conversation at will.

20. Authentic Happiness: Using the New Positive Psychology to Realise Your Potential for Lasting Fulfilment by Martin E. P. Seligman

You may have heard of this entry after its launch in 2004 caused international debate over the nature of real happiness. Authentic Happiness was the starting point for the science of Positive Psychology and the discussion of happiness in a scientific way. 

According to Martin Seligman, happiness has less to do with factors such as genes or luck, and more to do with focusing on your internal strengths rather than weaknesses. This isn’t to say that situational factors based on your genes wouldn’t impact you, or that being lucky enough to win the lottery wouldn’t change your life. Seligman’s point is that maintaining a positive mindset and building on one’s strengths is the most dependable route to long-lived happiness. To that end, Seligman supplies exercises, brief tests, and interesting programs that will help you identify your virtues and use them most efficiently.

21. Emotional Intelligence: Why It Can Matter More Than IQ by Daniel Goleman

It’s no secret that a high IQ doesn’t automatically make a  person smart or good (not to mention the long-standing debate over the reliability and biases of IQ tests). That said, what actually makes a person smart or good? Daniel Goleman’s innovative analyses in Emotional Intelligence certainly brings us closer to understanding. This book breaks down human processes into “two minds”, the rational and the emotional, to detail how they together shape the ways that we move through the world. 

Goleman draws on contemporary cognitive and behavioral research to show the factors that make higher IQ flounder where those with average IQ excel. The factors that go into this disparity are: self-awareness, self-discipline, and empathy, and their presence adds up to a completely different manner of intelligence. Luckily, this kind of emotional intelligence can be developed and strengthened at every age to ultimately benefit our health, work, and relationships.

22. The Psychology of Pandemics: Preparing for the Next Global Outbreak of Infectious Disease by Steven Taylor

Published in October 2019, just before the COVID-19 pandemic, Steven Taylor’s book about the importance of psychology in curbing the spread of deadly pandemics — stating that, at the time, the next pandemic could be soon — turned out to be frighteningly prophetic. Taylor posits that, while vaccinations and behavioral methods are crucial for stemming infection rates, psychological elements are equally important.

The Psychology of Pandemics explains psychology’s role in nonadherence to vaccination and hygiene programs and in mental health as people cope with the threat and loss of life. Taylor talks through every reason why understanding psychology is essential to managing societal problems that go hand-in-hand with pandemics. You need only consult a few history books to see that the same problems recurr every time we face a pandemic. These problems range from excessive fear to maladaptive behaviours to the xenophobia that occurs when people feel threatened by infection. Sound familiar? If you want to understand why the COVID-19 pandemic unfolded in the way it did, this is definitely on the list of the best psychology books to try.

23. Human Givens : A New Approach to Emotional Health and Clear Thinking by Joe Griffin and Ivan Tyrrell

Feeling like something a little more laidback? Human Givens is a guide to emotional and physical health, as well as education, using the “human givens” approach. Authors Joe Griffin and Ivan Tyrrell chronicle what some call the best psychological insight of this age — that we are all born with innate knowledge patterns known as “human givens”. These givens are experienced as physical and emotional needs, and only when those needs are met can one reach their full mental and physical potential. 

Griffin and Tyrrell suggest that how your innate needs connect with the world can shape not just your own health and happiness, but that of your family and friends. Human Givens takes this idea and looks at what every person needs to flourish, as well as how to actively pursue those things. Of course, this isn’t all just speculation: Griffin and Tyrell back up their approach with new scientific findings and ideas about how the mind works — as well as how to use those ideas to overcome the anxieties of the modern world.

24. Obedience to Authority: An Experimental View by Stanley Milgram

The next book on our list is what some might call a psychology classic. Psychologist Stanley Milgram performed a series of famous experiments in the 1960s with the view to better understanding obedience to authority, after numerous war criminals on trial had claimed they were “just following orders”. 

The experiments were controversial at the time, because they involved volunteer subjects being instructed to administer what they thought were progressively more painful shocks to another human being — the aim of this was to see how far people would obey orders even when they knew them to be morally gray. Though Milgram’s experiment was criticized for being immoral itself, it has since been vindicated as a breakthrough in understanding both obedience and psychology as a whole. Obedience to Authority has long been thought of as one of the best psychology books, offering Milgram’s personal insight into his groundbreaking methods, theories, and post-experiment conclusions.

25. Consciousness and the Social Brain by Michael S. A. Graziano

The final entry on our list delves into one of the great mysteries of the human race: the brain. How are we conscious, what is consciousness, and how does the brain create it? Why do some people have more of a constant running internal monologue than others? These are the big questions that Michael S. A. Graziano aims to tackle in Consciousness and the Social Brain.

The human brain has evolved a vastly complicated circuitry which allows it to be socially intelligent — one function of which is to be aware of others socially, to understand when someone other than oneself is thinking or feeling. Graziano’s theory is that the brain’s internal machinery that allows it to be aware of others also allows self awareness. The crux is that human awareness is layers upon layers of information that the brain has gathered, processed, and rendered — a wholly physical phenomena in the same way that generating heat or electricity might be. This is, of course, a hotly debated topic, with many people believing that to reduce the brain to only physicality would be reductive. Regardless of what you believe, Graziano’s scientific journey is a thrill to the last page!

This is an extremely comprehensive text for an undergraduate psychology course about research methods. It does an excellent job covering the basics of a variety of types of research design. It also includes important topics related to research such as ethics, finding journal articles, and writing reports in APA format.

Content Accuracy rating: 5

I did not notice any errors in this text.

Relevance/Longevity rating: 5

The content is very relevant. It will likely need to be updated over time in order to keep research examples relevant. Additionally, APA formatting guidelines may need to be updated when a new publication manual is released. However, these should be easy updates for the authors to make when the time comes.

Clarity rating: 5

This text is very clear and easy to follow. The explanations are easy for college students to understand. The authors use a lot of examples to help illustrate specific concepts. They also incorporate a variety of relevant outside sources (such as videos) to provide additional examples.

Consistency rating: 5

The text is consistent and flows well from one section to the next. At the end of each large section (similar to a chapter) the authors provide key takeaways and exercises.

Modularity rating: 5

This text is very modular. It is easy to pick and choose which sections you want to use in your course when. Each section can stand alone fairly easily.

Organization/Structure/Flow rating: 5

The text is very well organized. Information flows smoothly from one topic to the next.

Interface rating: 5

The interface is great. The text is easy to navigate and the images display well (I only noticed 1 image in which the formatting was a tad off).

Grammatical Errors rating: 5

I did not notice any grammatical errors.

Cultural Relevance rating: 5

The text is culturally relevant.

This is an excellent text for an undergraduate research methods course in the field of Psychology. I have been using the text for my Research Methods and Statistics course for a few years now. This text focuses on research methods, so I do use another text to cover statistical information. I do highly recommend this text for research methods. It is comprehensive, clear, and easy for students to use.

This textbook covers every topic that I teach in my Research Methods course aside from psychology careers (which I would not really expect it to cover).

I have not noticed any inaccurate information (other than directed students to read Malcolm Gladwell). I appreciate that the textbook includes information on research errors that have not been supported by replication efforts, such as embodied cognition.

Many of the basic concepts of research methods are rather timeless, but I appreciate that the text includes newer research as examples while also including "classic" studies that exemplify different methods.

The writing is clear and simple. The keywords are bolded and reveal a definition when clicked, which students often find very helpful. Many of the figures are very helpful in helping students understand various methods (I really like the ones in the single-subject design subchapter).

The book is very consistent in its terminology and writing style, which I see as a positive compared to other open psychology textbooks where each chapter is written by subject matter experts (such as the NOBA intro textbook).

Modularity rating: 4

I teach this textbook almost entirely in order (except for moving chapters 12 & 13 earlier in the semester to aid students in writing Results sections in their final papers). I think that the organization and consistency of the book reduces its modularity, in that earlier chapters are genuinely helpful for later chapters.

Organization/Structure/Flow rating: 4

I preferred the organization of previous editions, which had "Theory in Research" as its own chapter. If I were organizing the textbook, I am not sure that I would have out descriptive or inferential statistics as the final two chapters (I would have likely put Chapter 11: Presenting Your Research as the final chapter). I also would not have put information about replicability and open science in the inferential statistics section.

The text is easy to read and the formatting is attractive. My only minor complaint is that some of the longer subchapters can be a pretty long scroll, but I understand the desire for their only to be one page per subchapter/topic.

I have not noticed any grammatical errors.

Cultural Relevance rating: 3

I do not think the textbook is insensitive, but there is not much thought given to adapting research instruments across cultures. For instance, talking about how different constructs might have different underlying distributions in different cultures would be useful for students. In the survey methods section, a discussion of back translation or emic personality trait measurement/development for example might be a nice addition.

I choose to use this textbook in my methods classes, but I do miss the organization of the previous American editions. Overall, I recommend this textbook to my colleagues.

This text includes the majority of content included in our undergraduate Research Methods in Psychology course. The glossary provides concise definitions of key terms. This text includes most of the background knowledge we expect our students to have as well as skill-based sections that will support them in developing their own research projects.

The content I have read is accurate and error-free.

The content is relevant and up-to-date.

The text is clear and concise. I find it pleasantly readable and anticipate undergraduate students will find it readable and understandable as well.

The terminology appears to be consistent throughout the text.

The modular sections stand alone and lend themselves to alignment with the syllabus of a particular course. I anticipate readily selecting relevant modules to assign in my course.

The book is logically organized with clear and section headings and subheadings. Content on a particular topic is easy to locate.

The text is easy to navigate and the format/design are clean and clear. There are not interface issues, distortions or distracting format in the pdf or online versions.

The text is grammatically correct.

Cultural Relevance rating: 4

I have not found culturally insensitive and offensive language or content in the text. For my courses, I would add examples and supplemental materials that are relevant for students at a Tribal College.

This textbook includes supplemental instructor materials, included slides and worksheets. I plan to adopt this text this year in our Research Methods in Psychology course. I expect it to be a benefit to the course and students.

This text serves as an excellent resource for introducing survey research methods topics to undergraduate students. It begins with a background of the science of psychology, the scientific method, and research ethics, before moving into the main types of research. This text covers experimental, non-experimental, survey, and quasi-experimental approaches, among others. It extends to factorial and single subject research, and within each topic is a subset (such as observational research, field studies, etc.) depending on the section.

I could find no accuracy issues with the text, and appreciated the discussions of research and cited studies.

There are revised editions of this textbook (this being the 4th), and the examples are up to date and clear. The inclusion of exercises at the end of each chapter offer potential for students to continue working with material in meaningful ways as they move through the book and (and course).

The prose for this text is well aimed at the undergraduate population. This book can easily be utilized for freshman/sophomore level students. It introduces the scientific terminology surrounding research methods and experimental design in a clear way, and the authors provide extensive examples of different studies and applications.

Terminology is consistent throughout the text. Aligns well with other research methods and statistics sources, so the vocabulary is transferrable beyond the text itself.

Navigating this book is a breeze. There are 13 chapters, and each have subsections that can be assigned. Within each chapter subsection, there is a set of learning objectives, and paragraphs are mixed in with tables and figures for students to have different visuals. Different application assignments within each chapter are highlighted with boxes, so students can think more deeply given a set of constructs as they consider different information. The last subsection in each chapter has key summaries and exercises.

The sections and topics in this text are very straightforward. The authors begin with an introduction of psychology as a science, and move into the scientific method, research ethics, and psychological measurement. They then present multiple different research methodologies that are well known and heavily utilized within the social sciences, before concluding with information on how to present your research, and also analyze your data. The text even provides links throughout to other free resources for a reader.

This book can be navigated either online (using a drop-down menu), or as a pdf download, so students can have an electronic copy if needed. All pictures and text display properly on screen, with no distortions. Very easy to use.

There were no grammatical errors, and nothing distracting within the text.

This book includes inclusive material in the discussion of research ethics, as well as when giving examples of the different types of research approaches. While there is always room for improvement in terms of examples, I was satisfied with the breadth of research the authors presented.

This text provides an overview of both research methods, and a nice introduction to statistics for a social science student. It would be a good choice for a survey research methods class, and if looking to change a statistics class into an open resource class, could also serve as a great resource.

The comprehensiveness of this book was appropriate for an introductory undergraduate psychology course. Critical topics are covered that are necessary for psychology students to obtain foundational learning concepts for research. Sections within the text and each chapter provide areas for class discussion with students to dive deeper into key concepts for better learning comprehension. The text covered APA format along with examples of research studies to supplement the learning. The text segues appropriately by introducing the science of psychology, followed by scientific method and ethics before getting into the core of scientific research in the field of psychology. Details are provided in quantitative and qualitative research, correlations, surveys, and research design. Overall, the text is fully comprehensive and necessary introductory research concepts.

The text appears to be accurate with no issues related to content.

Relevance/Longevity rating: 4

The text provided relevant research information to support the learning. The content was up-to-date with a variety of different examples related to the different fields of psychology. However, some topics such as in the pseudoscience section were not very relevant and bordered the line of beliefs. Here, more current or relevant solid examples would provide more relevancy in this part of the text. Bringing in more solid or concrete examples that are more current for students may have been more appropriate such as lack of connection between information found on social media versus real science.

The language and flow of the chapters accompanied by the terms, concepts, and examples of applied research allows for clarity of learning content. Terms were introduced at the appropriate time with the support of concepts and current or classic research. The writing style flows nicely and segues easily from concept to concept. The text is easy for students to understand and grasp the details related to psychological research and science.

The text provides consistency in the outline of each chapter. The beginning section chapter starts objectives as an overview to help students unpack the learning content. Key terms are consistently bolded followed by concept or definition and relevant examples. Research examples are pertinent and provide students with an opportunity to understand application of the contents. Practice exercises are provided with in the chapter and at the and in order for students to integrate learning concepts from within the text.

Sections and subsections are clearly organized and divided appropriately for ease-of-use. The topics are easily discernible and follow the flow of ideal learning routines for students. The sections and subsections are consistently outlined for each concept module. The modularity provides consistency allowing for students to focus on content rather than trying to discern how to pull out the information differently from each chapter or section. In addition, each section and subsection allow for flexibility in learning or expanding concepts within the content area.

The organization of the textbook was easy to follow and each major topic was outlined clearly. However, the chapter on presenting research may be more appropriately placed toward the end of the book rather than in the middle of the chapters related to research and research design. In addition, more information could have been provided upfront around APA format so that students could identify the format of citations within the text as practice for students throughout the book.

The interface of the book lends itself to a nice layout with appropriate examples and links to break up the different sections in the chapters. Examples where appropriate and provided engagement opportunities for the students for each learning module. Images and QR codes or easily viewed and used. Key terms are highlighted in relevant figures, graphs, and tables were appropriately placed. Overall, the interface of the text assisted with the organization and flow of learning material.

No grammatical errors were detected in this book.

The text appears to be culturally sensitive and not offensive. A variety of current and classic research examples are relevant. However, more examples of research from women, minorities, and ethnicities would strengthen the culture of this textbook. Instructors may need to supplement some research in this area to provide additional inclusivity.

Overall, I was impressed by the layout of the textbook and the ease of use. The layout provides a set of expectations for students related to the routine of how the book is laid out and how students will be able to unpack the information. Research examples were relevant, although I see areas where I will supplement information. The book provides opportunities for students to dive deeper into the learning and have rich conversations in the classroom. I plan to start using the psychology textbook for my students starting next year.

The text is very thorough and covers all of the necessary topics for an undergraduate psychology research methods course. There is even coverage of qualitative research, case studies, and the replication crisis which I have not seen in some other texts.

There were no issues with the accuracy of the text.

The content is very up to date and relevant for a research methods course. The only updates that will likely be necessary in the coming years are updates to examples and modifications to the section on APA formatting.

The clarity of the writing was good, and the chapters were written in a way that was accessible and easy to follow.

I did not note any issues with consistency.

Each chapter is divided into multiple subsections. This makes the chapters even easier to read, as they are broken down into short and easy to navigate sections. These sections make it easy to assign readings as needed depending on which topics are being covered in class.

Organization/Structure/Flow rating: 3

The organization was one of the few areas of weakness, and I felt that the chapters were ordered somewhat oddly. However, this is something that is easily fixed, as chapters (and even subsections) can be assigned in whatever order is needed.

There were no issues of note with the interface, and the PDF of the text was easy to navigate.

The text was well written and there were no grammatical/writing errors of note.

Overall, the book did not contain any notable instances of bias. However, it would probably be appropriate to offer a more thorough discussion of the WEIRD problem in psychology research.

Pitched very well for a 200-level Research Methods course. This text provided students with solid basis for class discussion and the further development of their understanding of fundamental concepts.

No issues with accuracy.

Coverage was on target, relevant, and applicable, with good examples from a variety of subfields within Psychology.

Clearly written -- students often struggle with the dry, technical nature of concepts in Research Methods. Part of the reason I chose this text in the first place was how favorably it compared to other options in terms of clarity.

No problems with inconsistent of shifting language. This is extremely important in Research Methods, where there are many closely related terms. Language was consistent and compatible with other textbook options that were available to my students.

Chapters are broken down into sections that are reasonably sized and conceptually appropriate.

The organization of this textbook fit perfectly with the syllabus I've been using (in one form or another) for 15+ years.

This textbook was easy to navigate and available in a variety of formats.

Examples show an eye toward inclusivity. I did not detect any insensitive or offensive examples or undertones.

The topics covered seemed to be at an appropriate level for beginner undergraduate psychology students; the learning objectives for each subsection and the key takeaways and exercises for each chapter are also very helpful in guiding students’ attention to what is most relevant. The glossary is also thorough and a good resource for clear definitions. I would like to see a final chapter on a “big picture” or integrating key ideas of replication, meta-analysis, and open science.

Content Accuracy rating: 4

For the most part, I like the way information is presented. I had a few specific issues with definitions for ordinal variables being quantitative (1st, 2nd, 3rd aren’t really numbers as much as ranked categories), the lack of specificity about different forms of validity (face, content, criterion, and discriminant all just labeled “validity” whereas internal and external validity appear in different sections), and the lack of clear distinction between correlational and quasi-experimental variables (e.g., in some places, country of origin is listed as making a design quasi-experimental, but in other chapters it is defined as correlational).

Some of the specific studies/experiments mentioned do not seem like the best or most relevant for students to learn about the topics, but for the most part, content is up-to-date and can definitely be updated with new studies to illustrate concepts with relative ease.

Besides the few concepts I listed above in “accuracy”, I feel the text was very accessible, provides clear definitions, and many examples to illustrate any potential technical/jargon terms.

I did not notice any issues with inconsistent terms except for terms that do have more than one way of describing the same concept (e.g., 2-sample vs. independent samples t-test)

I assigned the chapters out of order with relative ease, and students did not comment about it being burdensome to navigate.

The order of chapters sometimes did not make sense to me (e.g., Experimental before Non-experimental designs, Quasi-experimental designs separate from other non-experimental designs, waiting until Chapter 11 to talk about writing), but for the most part, the chapter subsections were logical and clear.

Interface rating: 4

I had no issues navigating the online version of the textbook other than taking a while to figure out how to move forward and back within the text itself rather than going back to the table of contents (this might just be a browser issue, but is still worth considering).

No grammatical errors of note.

There was nothing explicitly insensitive or offensive about the text, but there were many places where I felt like more focus on diversity and individual differences could be helpful. For example, ethics and history of psychological testing would definitely be a place to bring in issues of systemic racism and/or sexism and a focus on WEIRD samples (which is mentioned briefly at another point).

I was very satisfied with this free resource overall, and I recommend it for beginning level undergraduate psychology research methods courses.

This book covers essential topics and areas related to conducting introductory psychological research. It covers all critical topics, including the scientific method, research ethics, research designs, and basic descriptive and inferential statistics. It even goes beyond other texts in terms of offering specific guidance in areas like how to conduct research literature searches and psychological measurement development. The only area that appears slightly lacking is detailed guidance in the mechanics of writing in APA style (though excellent basic information is provided in chapter 11).

All content appears accurate. For example, experimental designs discussed, descriptive and inferential statistical guidance, and critical ethical issues are all accurately addressed, See comment on relevance below regarding some outdated information.

Relevance/Longevity rating: 3

Chapter 11 on APA style does not appear to cover the most current version of the APA style guide (7th edition). While much of the information in Chapter 11 is still current, there are specifics that did change from 6th to 7th edition of the APA manual and so, in order to be current, this information would have to be supplemented with external sources.

The book is extremely well organized, written in language and terms that should be easily understood by undergraduate freshmen, and explains all necessary technical jargon.

The text is consistent throughout in terms of terminology and the organizational framework (which aids in the readability of the text).

The text is divided into intuitive and common units based on basic psychological research methodology. It is clear and easy to follow and is divided in a way that would allow omission of some information if necessary (such as "single subject research") or reorganization of information (such as presenting survey research before experimental research) without disruption to the course as a whole.

As stated previously, the book is organized in a clear and logical fashion. Not only are the chapters presented in a logical order (starting with basic and critical information like overviews of the scientific method and research ethics and progressing to more complex topics like statistical analyses).

No issues with interface were noted. Helpful images/charts/web resources (e.g., Youtube videos) are embedded throughout and are even easy to follow in a print version of the text.

No grammatical issues were noted.

No issues with cultural bias are noted. Examples are included that address topics that are culturally sensitive in nature.

I ordered a print version of the text so that I could also view it as students would who prefer a print version. I am extremely impressed with what is offered. It covers all of the key content that I am currently covering with a (non-open source) textbook in an introduction to research methods course. The only concern I have is that APA style is not completely current and would need to be supplemented with a style guide. However, I consider this a minimal issue given all of the many strengths of the book.

Includes the majority of elements you expect from a textbook covering research methods. Some topics that could have been covered in a bit more depth were factorial research designs (no coverage of 3 or more independent variables) and external validity (or the validities in general).

Nothing found that was inaccurate.

Looks like a few updates could be made to chapter 11 to bring it up to date with APA 7. Otherwise, most examples are current.

Very clear, a great fit for those very new to the topic.

The framework is clear and logical, and the learning objectives are very helpful for orienting the reader immediately to the main goals of each section.

Subsections are well-organized and clear. Titles for sections and subsections are clear.

Though I think the flow of this textbook for the most part is excellent, I would make two changes: move chapter 5 down with the other chapters on experimental research and move chapter 11 to the very end. I feel that this would allow for a more logical presentation of content.

The webpage navigation is easy to use and intuitive, the ebook download works as designed, and the page can be embedded directly into a variety of LMS sites or used with a variety of devices.

I found no grammatical errors in this book.

While there were some examples of studies that included participants from several cultures, the book does not touch on ecological validity, an important external validity issue tied to cultural psychology, and there is no mention of the WEIRD culture issue in psychology, which seems somewhat necessary when orienting new psychology students to research methods today.

I currently use and enjoy this textbook in my research methods class. Overall, it has been a great addition to the course, and I am easily able to supplement any areas that I feel aren't covered with enough breadth.

The content connects to classic, timeless examples in the field, but also mixes in a fair amount of more current, relatable examples. I feel like I'll be able to use this version of the text for many years without its age showing.

The authors present a clear and efficient writing style throughout that is rich with relatable examples. The only area that may be a bit much for undergraduate-level student understanding is the topic of statistics. I personally scale back my discussion of statistics in my Intro to Research Methods course, but for those that prefer a deeper dive, the higher-level elements are there.

I did not notice any shifts with the use of terminology or with the structural framework of the text. The text is very consistent and organized in an easily digestible way.

The authors do a fantastic job breaking complex topics down into manageable chunks both as a whole and within chapters. As I was reading, I could easily see how I could align my current approach of teaching Intro to Research Methods with their modulated presentation of the material.

I effortlessly moved through the text given the structural organization. All topics are presented in a logical fashion that allowed each message to be delivered to the reader with ease.

I read the text through the PDF version and found no issue with the interface. All image and text-based material was presented clearly.

I cannot recall coming across any grammatical errors. The text is very well written.

I did not find the text to be culturally insensitive in any way. The authors use inclusive language and even encourage that style of writing in the chapter on Presenting Your Research. I would have liked to see more cross-cultural research examples and more of an extended effort to include the theme of diversity throughout, but at no point did I find the text to be offensive.

This is a fantastic text and I look forward to adopting it for my Intro to Research Methods course in the Spring. :)

This text edition has covered all ideas and areas of research methods in psychology. It has provided a glossary of terms, sample APA format, and sample research papers. 

The content is unbiased, accurate, and I did not find any errors in the text. 

The content is current and up-to-date. I found that the text can be added to should material change, the arrangement of the text/content makes it easily accessible to add material, if necessary. 

The text is clear, easy to understand, simplistic writing at times, but I find this text easy for students to comprehend. All text is relevant to the content of behavioral research. 

The text and terminology is consistent. 

The text is organized well and sectioned appropriately. The information is presented in an easy-to-read format, with sections that can be assigned at various points during the semester and the reader can easily locate this. 

The topics in the text are organized in a logical and clear manner. It flows really well. 

The text is presented well, including charts, diagrams, and images. There did not appear to be any confusion with this text. 

The text contains no grammatical errors.

The text was culturally appropriate and not offensive. Clear examples of potential biases were outlined in this text which I found quite helpful for the reader. 

Overall, I found this to be a great edition. Much of the time I spend researching outside material for students has been included in this text. I enjoyed the format, easier to navigate, helpful to students by providing an updated version of discussions and practice assignments, and visually more appealing.

All of the main topics in a Research Methods course are covered in this textbook (e.g., scientific method, ethics, measurement, experimental design, hypothesis testing, APA style, etc.). Some of these topics are not covered as in-depth as in other Research Method textbooks I have used previously, but this actually may be a positive depending on the students and course level (that is, students may only need a solid overview of certain topics without getting overwhelmed with too many details). It also gives the instructor the ability to add content as needed, which helps with flexibility in course design.

I did not note any errors or inaccurate/biasing statements in the text.

For the most part, everything was up to date. There was a good mix of classic research and newer studies presented and/or used as examples, which kept the chapters interesting, topical and relevant. I only noted the section on APA Style in the chapter “Presenting Your Research” which may need some updating to be in line with the new APA 7th edition. However, there should be only minor edits needed (the chapter itself was great overview and introduction to the main points of APA style) and it looks like they should be relatively easy to implement.

The text was very well-written and was presented at an accessible level for undergraduates new to Research Methods. Terms were well-defined with a helpful glossary at the end of the textbook.

The consistent structure of the textbook is huge positive. Each chapter begins with learning objectives and ends with bulleted key takeaways. There are also good exercises and learning activities for students at the end of each chapter. Instructors may need to add their own activities for chapters that do not go into a lot of depth (there are also instructor resources online, which may have more options available).

This is one of the biggest strengths of this textbook, in my opinion. I appreciate how each chapter is broken down into clearly defined subsections. The chapters and the subsections, in particular, are not lengthy, which is great for students’ learning. These subsections could be reorganized and used in a variety of ways to suit the needs of a particular course (or even as standalone subsections).

The topics were presented in a logical manner. As mentioned above, since the textbook is very modular, I feel that you could easily rearrange the chapters to fit your needs (for example, presenting survey design before experimental research or making the presenting your research section a standalone unit).

I downloaded the textbook as an ebook, which was very easy to use/navigate. There were no problems reading any of the text or figures/tables. I also appreciated that you could open the ebook using a variety of apps (Kindle, iBook, etc.) depending on your preference (and this is good for students who have a variety of technical needs).

There were no grammatical errors noted.

The examples were inclusive of races, ethnicity and background and there were not any examples that were culturally insensitive or offensive in any way. In future iterations of the replicability section, it may be beneficial to touch upon the “weird” phenomena in psychology research (that many studies use participants who are western, educated and from industrialized, rich and democratic countries) as a point to engage students in improving psychological practices.

I will definitely consider switching to this textbook in the future for Research Methods.

Hits all the necessary marks from ways of knowing to measurement, research designs, and presentation. Comparable in detail and content to other Research Methods texts I have used for teaching.

Correct and to the point. Complex ideas such as internal consistency reliability and discriminant validity are well handled--correct descriptions that are also succinct and articulated simply and with clear examples that are easy for a student reader to grasp.

Seems likely to have good staying power. One area that has changed quickly in the past is the usefulness of various research data bases. So it is possible that portion could become more quickly outdated, but there is no predicting that. The current descriptions are useful.

Very clearly written without being condescending, overly casual or clunky.

Excellent consistency throughout in terms of organization, language usage, level of detail and tone.

Imho this is one of the particular strengths of the text. Chapters are well divided into discrete parts, which seems likely to be a benefit in cohorts of students who are increasingly accustomed to digesting small amounts of information.

Well organized, straightforward structure that is maintained throughout.

No problems with the interface.

The grammar level is another notable strength. Ideas are articulated clearly, and with sophistication, but in a syntactically very straightforward manner.

The text isn't biased or offensive. I wish that to illustrate various points and research designs it had drawn more frequently on research studies that incorporate a specific focus on race and ethnicity.

This is a very good text. As good as any for profit text I have used to teach a research methods course, if not better.

As other reviews have mentioned, this textbook provides a comprehensive look at multiple concepts for an introductory course in research methods in psychology. Some of the concepts (i.e., variables, external validity) are briefly described and glossed over that it will take additional information, examples, and reinforcement from instructors in the classroom. Other sections and concepts, like ethics or reporting of research were well-described and thorough.

It appeared that the information was accurate, error-free, and unbiased.

The information is up-to-date. In the section on APA presentation, it looks like the minor adjustments to the APA Publication Manual 7th Edition would need to be included. However, this section gives a good foundation and the instructor can easily implement the changes.

Clarity rating: 4

The text is clearly written written and provides an appropriate context when terminology is used.

There aren't any issues with consistency in the textbook.

The division of smaller sections can be beneficial when reading it and assigning it to classes. The sections are clearly organized based on learning objectives.

The textbook is organized in a logical, clear manner. There may be topics that instructors choose to present in a different manner (non-experimental and survey research prior to experimental). However, this doesn't generally impact the organization and flow of the book.

While reading and utilizing the book, there weren't any navigation issues that could impact the readability of the book. Students could find this textbook easy to use.

Grammatical errors were not noted.

There weren't any issues with cultural sensitivity in the examples of studies used in the textbook.

The text is comprehensive with an effective glossary of terms at the end. It would be beneficial to include additional examples and exercises for students to better understand concepts covered in Chapter II, Overview of the Scientific Method, Chapter IV, Psychological Measurement, and Chapter XII Descriptive Statistics.

The text is accurate and there are minimal type/grammatical errors throughout. The verbiage is written in an unbiased manner consistently throughout the textbook.

The content is up-to-date, and examples can be easily updated for future versions. As a public health instructor, I would be interested in seeing examples of community-based examples in future versions. The current examples provided are relevant for undergraduate public health students as well as psychology students.

The text is written in a clear manner. The studies used can be easily understood by undergraduate students in other social science fields, such as public health. More examples and exercises using inferential statistics would be helpful for students to better grasp the concepts.

The framework for each chapter and terminology used are consistent. It is helpful that each section within each chapter begins with learning objectives and the chapter ends with key takeaways and exercises.

The text is clearly divided into sections within each chapter. When I first started reviewing this textbook, I thought each section was actually a very short chapter. I would recommend including a listing of all of the objectives covered in each chapter at the beginning to improve the modularity of the text.

Some of the topics do not follow a logical order. For example, it would be more appropriate to discuss ethics before providing the overview of the scientific method. It would be better to discuss statistics used to determine results before describing how to write manuscripts. However, the text is written in a way that that the chapters could be assigned to students in a different order without impacting the students’ comprehension of the concepts.

I did not encounter any interface issues when reviewing this text. All links worked and there were no distortions of the images or charts that may confuse the reader. There are several data tables throughout the text which are left-aligned and there is a large amount of empty white space next it. I would rearrange the text in future versions to make better use of this space.

The text contains minimal grammatical errors.

The examples are culturally relevant. I did not see any examples that may be considered culturally insensitive or offensive in any way.

As an instructor for an undergraduate public health sciences and methods course, I will consider using some of the content in this text to supplement the current textbook in the future.

Successfully spans the gamut of topics expected in a Research Methods textbook. Some topics are covered in-depth, while others are addressed only at a surface level. Instructors may therefore need to carefully arrange class material for topics in which depth of knowledge is an important learning outcome.

The factual content was error-free, according to my reading. I did spot a few grammatical and typographical errors, but they were infrequent and minor.

Great to see nuanced—although limited—discussion of issues with Null Hypothesis Significance Testing, Reproducibility in Psychological Science, and so forth. I expect that these areas are likely to grow in future editions, perhaps supplementing or even replacing more traditional material.

Extremely easy to read with multiple examples throughout to illustrate the principles being covered. Many of these examples are "classics" that students can easily relate to. Plus, who doesn't like XKCD comics?

The textbook is structured sensibly. At times, certain authors' "voices" seemed apparent in the writing, but I suspect this variability is unlikely to be noticed by or even bothersome to the vast majority of readers.

The topics are easily divisible and seem to follow routine expectations. Instructors might find it beneficial and/or necessary to incorporate some of the statistical thinking and learning into various earlier chapters to facilitate student understanding in-the-moment, rather than trying to leave all the statistics to the end.

Sensible and easy-to-follow structure. As per "Modularity", the Statistical sections may benefit from instructors folding in such learning throughout, rather than only at the end.

Beautifully presented, crisp, easy-to-read and navigate. Caveat: I read this online, in a web-browser, on only one device. I haven't tested across multiple platforms.

High quality writing throughout. Only a few minor slip-ups that could be easily fixed.

Includes limited culturally relevant material where appropriate.

The authors do a great job of simplifying the concepts of research methods and presenting them in a way that is understandable. There is a tradeoff between brevity and depth here. Faculty who adopt this textbook may need to spend more time in class going in depth into concepts, rather than relying on the textbook for all of the information related to key concepts. The text does not cover qualitative methods in detail.

The textbook provides an accurate picture of research methods. The tone is objective and without bias.

The textbook is highly relevant and up to date. Examples are drawn from modern theories and articles.

The writing is a fantastic mix of objective and authoritative while also being approachable.

The book coheres well together. Each chapter and section are uniform.

This book fits very well within a traditional 16 week semester, covering roughly a chapter per week. One could take out specific chapters and assign them individually if research methods is taught in a different way from a standard research textbook.

Content is very well organized. The table of contents is easy to navigate and each chapter is presented in a clear and consistent manner. The use of a two-tier table of contents is particularly helpful.

Standard pressbooks interface, which is great. Uses all of the standard components of Pressbooks well, though the lack of H5P and interactive content is a drawback.

Most content areas in this textbook were covered appropriately extensively. Notably, this textbook included some content that is commonly missing in other textbooks (e.g. presenting your research). There were some areas where more elaboration and more examples were needed. For example, the section covering measurement validities included all the important concepts, but needed more guidance for student comprehension. Also, the beginning chapters on 'common sense' reasoning and pseudoscience seemed a little too brief.

Overall, this textbook appeared to be free from glaring errors. There were a couple of instances of concern, but were not errors, per se. For example, the cut-off for Cronbach's alpha was stated definitively at .80, while this value likely would be debated among researchers.

This textbook was presented in such a way that seemed protect it from becoming obsolete within the next few years. This is important for continued, consistent use of the book. The authors have revised this book, and those revisions are clearly summarized in the text. Importantly, the APA section of the textbook appears to be up-to-date. Also, the use of QR codes throughout the text is a nice touch that students may appreciate.

Connected to comprehensiveness, there are some important content areas that I felt were lacking in elaboration and examples (e.g. testing the validity of measurement; introduction of experimental design), which inhibits clarity. Overall, however, the topics seemed to be presented in a straightforward, accessible manner. The textbook includes links to informative videos and walk-throughs where appropriate, which seem to be potentially beneficial for student comprehension. The textbook includes tools designed to aid learning, namely "Key Takeaways" and "Exercises" sections at the end of most modules, but not all. "Key Takeaways" seemed valuable, as they were a nice bookend to the learning objectives stated at the beginning of each module. "Exercises" did not appear to be as valuable, especially for the less-motivated student. On their face, these seemed to be more designed for instructors to use as class activities/active learning. Lastly, many modules of the textbook were text-heavy and visually unappealing. While this is superficial, the inclusion of additional graphics, example boxes, or figures in these text-heavy modules might be beneficial.

The textbook appeared to be internally consistent with its approach and use of terminology.

The textbook had a tendency to 'throw out' big concepts very briefly in earlier modules (e.g. sampling, experimental/non-experimental design), and then cover them in more detail in later modules. This would have been less problematic if the text would explicitly inform the student that these concepts would be elaborated upon later. Beyond this issue, the textbook seems to lend itself to being divided up and used on module-by-module basis.

The organization of the chapters did not make intuitive sense to me. The fact that correlation followed experimental research, and that descriptive research was the second-to-last module in the sequence was confusing. That said, textbook is written in such a way that an instructor easily assign the modules in the order that works best for their class.

Overall, the interface worked smoothly and there were few technical issues. Where there were issues (e.g. inconsistent spacing between lines and words), they were negligible.

The text seemed to be free from glaring grammatical problems.

Because this is a methodology textbook, it does not lend itself to too much cultural criticism. That said, the book did not rely on overly controversial examples, but also didn't shy away from important cultural topics (e.g. gender stereotypes, vaccines).

The book covers all areas related to research methods, not only for the field of psychology, but also to other related fields like exercise science. Topics include ethics, developing a research questions, experimental designs, non-experimental designs, and basic statistics, making this book a great resource for undergraduate research methods classes.

Reviewed content is accurate and seems free of any personal bias.

The topic of research methods in general is not expected to change quickly. It is not expected that this text will become obsolete in the near future. Furthermore, for both the field of psychology as well as other related fields, the examples will continue to have an application to explain certain concepts and will not be outdated soon, even with new research emerging every day.

The text is written so an undergraduate student should be able to understand the concepts. The examples provided in the text greatly contribute to the understanding of the topics and the proposed exercises at the end of each chapter will further apply the knowledge.

The layout and writing style are consistent throughout the text.

Layout of the text is clear, with multiple subsection within each chapter. Each chapter can easily be split into multiple subsection to assign to students. No evidence of self-refers was observed, and individual chapters could be assigned to students without needed to read all preceding chapters. For example, Chapter 4 may not be particularly useful to students outside of psychology, but an instructor can easily reorganize the text and skip this chapter while students can still understand following chapters.

Topics are addressed in a logical manner. Overall, an introduction to research is provided first (including ethics to research), which is followed by different types of research, and concludes with types of analysis.

No images or tables are distorted, making the text easy to read.

No grammatical errors observed in text.

Text is not offensive and does not appear to be culturally insensitive.

I believe that this book is a great resource and, as mentioned previously, can be used for a wider audience than just psychology as the basics of research methods can be applied to various fields, including exercise science.

All appropriate areas and topics are covered in the text. In that sense, this book is equivalent to other top texts dealing with research methods in psychology. The appeal of this book is the brevity and clarity. Therefore, some may find that, although the topics are covered, topics may not be covered as thoroughly they might like. Overall, the coverage is solid for an introductory course in research methods.

In terms of presentation, this book could be more comprehensive. Each chapter does start with a set of learning objectives and ends with "takeaways" and a short set of exercises. However, it lacks detailed chapter outlines, summaries, and glossaries. Furthermore, an index does not accompany the text.

I found the book to be accurate with content being fairly presented. There was no underlying bias throughout the book.

This is an introductory text for research methods. The basics of research methods have been consistent for some time. The examples used in the text fit the concepts well. Therefore, it should not be quickly dated. It is organized in such a way that sections could be easily modified with more current examples as needed.

The text is easy to read. It is succinct yet engaging. Examples are clear and terminology is adequately defined.

New terms and concepts are dealt with chapter by chapter. However, those things which go across chapters are consistently presented.

The material for each chapter is presented in subsections with each subsection being tied to a particular learning objective. It is possible to use the book by subsection instead of by chapter. In fact, I did that during class by discussing the majority of one chapter, discussing another chapter, and then covering what I previously skipped,

In general, the book follows a "traditional" organization, matching the organization of many competing books. As mentioned in regard to modularity, I did not follow the organization of the book exactly as it was laid out. This may not necessarily reflect poorly on the book, however, since I have never followed the order of any research methods book. My three exams covered chapter 1 through 4, chapters 5, 6, part of 8, and chapters 7, the remainder of 8, 9, and 10. Once we collected data I covered chapters 11 through 13.

Interface rating: 3

The text and images are clear and distortion free. The text is available in several formats including epub, pdf, mobi, odt, and wxr. Unfortunately, the electronic format is not taken full advantage of. The text could be more interactive. As it is, it is just text and images. Therefore, the interface could be improved.

The book appeared to be well written and edited.

I did not find anything in the book that was culturally insensitive or offensive. However, more examples of cross-cultural research could be included.

I was, honestly, surprised by how much I liked the text. The material was presented in easy to follow format that is consistent with how I think about research methods. That made the text extremely easy to use. Students also thought the book was highly accessible Each chapter was relatively short but informative and easy to read.

This book covers all relevant topics for an introduction to research methods course in the social sciences, including measurement, sampling, basic research design, and ethics. The chapters were long enough to be somewhat comprehensive, but short enough to be digestible for students in an introductory-level class. Student reviews of the book have so far been very positive. The only section of the text for which more detail may be helpful is 2.3 (Reviewing the Research Literature), in which more specific instructions related to literature searches may be helpful to students.

I did not notice any issues related to accuracy. Content appeared to be accurate, error-free, and unbiased.

One advantage of this book is that it is relevant to other applied fields outside of psychology (e.g., social work, counseling, etc.). Also, the exercises at the end of chapter sections are helpful.

The clarity of the text provides students with succinct definitions for research-related concepts, without unnecessary discipline-specific jargon. One suggestion for future editions would be to make the distinctions between different types of non-experimental research a bit more clear for students in introductory classes (e.g., "Correlational Research" in Section 7.2).

Formatting and terminology was consistent throughout this text.

A nice feature of this book is that instructors can select individual sections within chapters, or even jump between sections within chapters. For example, Section 1.4 may not fit for a class that is less clinically-oriented in nature.

The flow of the text was appropriate, with ethics close to the beginning of the book (and an entire chapter devoted to it), and descriptive/inferential statistics at the end.

I did not notice any problems related to interface. I had no trouble accessing or reading the text, and the images were clear.

The text contained no discernible grammatical errors.

The book does not appear to be culturally insensitive in any discernible way, and explicitly addresses prejudice in research (e.g., Section 5.2). However, I think that continuing to add more examples that relate to specific marginalized groups would help improve the text (and especially exercises).

Overall, this book is very useful for an introductory research methods course in psychology or social work, and I highly recommend.

The content of the Research Methods in Psychology textbook was very thorough and covered what I would consider to be the important concepts and issues pertaining to research methods. I would judge that the textbook has a comparable coverage of information to other textbooks I have reviewed, including the current textbook I am using. The range of scholarly sources included in the textbook was good, with an appropriate balance between older and classic research examples and newer more cutting edge research information. Overall, the textbook provides substantive coverage of the science of conducting research in the field of psychology, supported by good examples, and thoughtful questions.

The textbook adopts a coherent and student-friendly format, and offers a precise introduction to psychological research methodology that includes consideration of a broad range of qualitative and quantitative methods to help students identify and evaluate the best approach for their research needs. The textbook offers a detailed review of the way that psychological researchers approach their craft. The author guides the reader through all aspects of the research process including formulating objectives, choosing research methods, securing research participants, as well as advice on how to effectively collect, analyze and interpret data and disseminate those findings to others through a variety of presentation and publication venues. The textbook offers relevant supplemental information in textboxes that is highly relevant to the material in the accompanying text and should prove helpful to learners. Likewise the graphics and figures that are included are highly relevant and clearly linked to the material presented in the text. The information covered by the textbook reflects an accurate summary of current techniques and methods used in research in the field of psychology. The presentation of information addresses the pros and cons of different research strategies in an objective and evenhanded way.

The range of scholarly sources included in the textbook was good, with an appropriate balance between older, classic research evidence and newer, cutting edge research. Overall, the textbook provides substantive coverage of the science on most topics in research methods of psychology, supported by good case studies, and thoughtful questions. The book is generally up to date, with adequate coverage of basic data collection methods and statistical techniques. Likewise the review of APA style guidelines is reflects the current manual and I like the way the author summarizes changes from the older version of the APA manual. The organization of the textbook does appear to lend itself to editing and adding new information with updates in the future.

I found the textbook chapters to be well written, in a straightforward yet conversational manner. It gives the reader an impression of being taught by a knowledgeable yet approachable expert. The writing style gives the learner a feeling of being guided through the lessons and supported in a very conversational approach. The experience of reading the textbook is less like being taught and more like a colleague sharing information. Furthermore, the style keeps the reader engaged but doesn't detract from its educational purpose. I also appreciate that the writing is appropriately concise. No explanations are so wordy as to overwhelm or lull the reader to sleep, but at the same time the information is not so vague that the reader can't understand the point at all.

The book’s main aim is to enable students to develop their own skills as researchers, so they can generate and advance common knowledge on a variety of psychological topics. The book achieves this objective by introducing its readers, step-by-step, to psychological research design, while maintaining an excellent balance between substance and attention grabbing examples that is uncommon in other research methods textbooks. Its accessible language and easy-to-follow structure and examples lend themselves to encouraging readers to move away from the mere memorization of facts, formulas and techniques towards a more critical evaluation of their own ideas and work – both inside and outside the classroom. The content of the chapters have a very good flow that help the reader to connect information in a progressive manner as they proceed through the textbook.

Each chapter goes into adequate depth in reviewing both past and current research related to the topic that it covers for an undergraduate textbook on research methods in psychology. The information within each chapter flows well from point-to-point, so that the reader comes away feeling like there is a progression in the information presented. The only limitation that I see is that I felt the author could do a little more to let the reader know how information is connected from chapter to chapter. Rather than just drawing the reader’s attention to things that were mentioned in previous chapters, it would be nice to have brief comments about how issues in one chapter relate to topics covered in previous chapters.

In my opinion the chapters are arranged in easily digestible units that are manageable in 30-40 minute reading sessions. In fact, the author designed the chapters of the textbook in a way to make it easy to chunk information, and start and stop to easily pick up where one leaves off from one reading session to another. I also found the flow of information to be appropriate, with chapters containing just the right amount of detail for use in my introductory course in research methods in psychology.

The book is organized into thirteen chapters. The order of the chapters offers a logical progression from a broad overview of information about the principles and theory behind research in psychology, to more specific issues concerning the techniques and mechanics of conducting research. Each chapter ends with a summary of key takeaways from the chapter and exercises that do more than ask for content regurgitation. I find the organization of the textbook to be effective, and matches my approach to the course very well. I would not make any changes to the overall format with the exception of moving chapter 11 on presenting research to the end of the textbook, after the chapters on statistical analysis and interpretation.

I found the quality of the appearance of the textbook to be very good. The textbook features appropriate text and section/header font sizes that allow for an adequate zooming level to read large or smalls sections of text, that will give readers flexibility to match their personal preference. There are learning objectives at the start of each chapter to help students know what to expect. Key terms are highlighted in a separate color that are easily distinguishable in the body of the page. There are very useful visuals in every chapter, including tables, figures, and graphs. Relevant supplemental information is also highlighted in well formatted text boxes that are color coded to indicate what type of information is included. My only criticism is that the photographs included in the text are of low quality, and there are so few in the textbook that I feel it would have been better to just leave them out.

I found no grammatical errors in my review of the textbook. The textbook is generally well written, and the style of writing is at a level that is appropriate for an undergraduate class.

Although the textbook contains no instances of presenting information that is cultural insensitive or offensive, it does not offer an culturally inclusive review of information pertaining to research methods in psychology. I found no inclusion of examples of research conducting with non European American samples included in the summary of studies. Likewise the authors do place much attention on the issue of cultural sensitivity when conducing research. If there is one major weakness of the textbook I would say it is in this area, but based on my experience it is not an uncommon characteristic of textbooks on research methods in psychology.

Short and sweet in most areas. Covers the basic concepts, not very comprehensively but definitely adequately so for a general beginning-level research methods course. For instance, I would liked to have seen a "separate" chapter on correlational research (there is one on single subject research and one on survey research), a discussion of the importance of providing a theoretical rationale for "getting an idea" (most students are fine with finding interesting and feasible project ideas but cannot give a theoretical rationale) before or after Chapter 4 on Theory, or a chapter on neuroscientific methods, which are becoming more and more popular. Nevertheless, it touches on most traditional areas that are in other books.

I did not find any errors or biases

This is one area where there is not much danger of going obsolete any time soon. The examples might need to be updated periodically (my students tend to not like dated materials, however relevant), but that should be easy.

Very clear and accessible prose. Despite the brevity, the concepts are put forth quite clearly. I like the "not much fluff" mentality. There is also adequate explanations of jargon and technical terminology.

I could not find any inconsistencies. The style and exposition frameworks are also quite consistent.

Yes, the modularity is fine. The chapters follow a logical pattern, so there should not be too much of a need for jumping around. And even if jumping around is needed depending on teaching style, the sections are solid in terms of being able to stand alone (or as an accompaniment to lectures).

Yes, the contents is ordered logically and the high modularity helps with any reorganization that an instructor may favor. In my case, for instance, Ch. 1 is fine, but I would skip it because it's mostly a repetition of what most introductory psychology books also say. I would also discuss non-experimental methods before going into experimental design. But such changes are easy to do, and if someone followed the book's own organization, there would also be a logical flow.

As far as I could see, the text is free of significant interface issues, at least in the pdf version

I could not find any errors.

As far as I could see, the book was culturally relevant.

I loved the short and sweet learning objectives, key takeaway sections, and the exercises. They are not overwhelming and can be used in class discussions, too.

This text covers the typical areas for an undergraduate psychology course in research design. There is no table of contents included with the downloadable version, although there is a table of contents on the website (which excludes sub-sections of chapters). The sections on statistics are not extensive enough to be useful in and of themselves, but they are useful for transitions to a follow-up statistics course. There does not seem to be a glossary of terms, which made it difficult at times for my read through and I assume later for students who decide to print the text. The text is comprehensive without being wordy or tedious.

Relatively minor errors; There does not seem to be explicit cultural or methodological bias in the text.

The content is up-to-date, and examples from the psychology literature are generally within the last 25 years. Barring extensive restructuring in the fundamentals of methodology and design in psychology, any updates will be very easy to implement.

Text will be very clear and easy to read for students fluent in English. There is little jargon/technical terminology used, and the vocabulary that is provided in the text is contemporary

There do not seem to be obvious shifts in the terminology or the framework. The text is internally consistent in that regard.

The text is well divided into chapter and subsections. Each chapter is relatively self-contained, so there are little issues with referring to past material that may have been skipped. The learning objectives at the beginning of the chapter are very useful. Blocks of text are well divided with headings.

As mentioned above, the topics of the text follow the well-established trajectory of undergraduate psychology courses. This makes it very logical and clear.

The lack of a good table of contents made it difficult to navigate the text for my read through. There were links to an outside photo-hosting website (flickr) for some of the stock photos, which contained the photos of the original creators of the photos. This may be distracting or confusing to readers. However, the hyperlinks in general helped with navigation with the PDF.

No more grammatical errors than a standard, edited textbook.

Very few examples explicitly include other races, ethnicities, or backgrounds, however the examples seem to intentionally avoid cultural bias. Overall, the writing seems to be appropriately focused on avoiding culturally insensitive or offensive content.

After having examined several textbooks on research design and methodology related to psychology, this book stands out as superior.

"Research Methods in Psychology" covers most research method topics comprehensively. The author does an excellent job explaining main concepts. The chapter on causation is very detailed and well-written as well as the chapter on research ethics. However, the explanations of data analysis seem to address upper level students rather than beginners. For example, in the “Describing Statistical Relationships” chapter, the author does not give detailed enough explanations for key terms. A reader who is not versed in research terminology, in my opinion, would struggle to understand the process. While most topics are covered, there are some large gaps. For example, this textbook has very little content related to qualitative research methods (five pages).

The content appears to be accurate and unbias.

The majority of the content will not become obsolete within a short time period-- many of the information can be used for the coming years, as the information provided is, overall, general in nature. The notably exceptions are the content on APA Code of Ethics and the APA Publication Manual, which both rely heavily on outdated versions, which limits the usefulness of these sections. In addition, it would be helpful to incorporate research studies that have been published after 2011.

The majority of the text is clear, with content that is easy for undergraduate students to read and understand. The key points included in the chapters are helpful, but some chapters seem to be missing key points (i.e., the key points do not accurately represent the overall chapter).

The text seems to be internally consistent in its terminology and organization.

Each chapter is broken into subsections that can be used alone. For example, section 5.2 covers reliability and validity of measurement. This could be extremely helpful for educators to select specific content for assigned readings.

The topics are presented in a logical matter for the most part. However, the PDF version of the book does not include a table of contents, and none of the formats has a glossary or index. This can make it difficult to quickly navigate to specific topics or terms, especially when explanations do not appear where expected. For example, the definitions of independent and dependent variables is provided under the heading “Correlation Does Not Imply Causation” (p. 22).

The text is consistent but needs more visual representations throughout the book, rather than heavily in some chapters and none at all in other chapters. Similarly, the text within the chapters is not easily readable due to the large sections of text with little to no graphics or breaks.

The interface of the text is adequate. However, the formatting of the PDF is sometimes weak. For example, the textbook has a number of pages with large blank spaces and other pages are taken up with large photos or graphics. The number of pages (and cost of printing) could have been reduced, or more graphics added to maximize utility.

I found no grammatical errors.

Text appears to be culturally sensitive. I appreciated the inclusion of the content about avoiding biased language (chapter 11).

Instructors who adopt this book would likely benefit from either selecting certain chapters/modules and/or integrating multiple texts together to address the shortcomings of this text. Further, the sole focus on psychology limits the use of this textbook for introductory research methods for other disciplines (e.g., social work, sociology).

The text book provides good information in certain areas, while not comprehensive information in other areas. The text provides practical information, especially the section on survey development was good. Additional information on sampling strategies would have been beneficial for the readers.

There are no errors.

Research method is a common topic and the fundamentals of it will not change over the years. Therefore, the book is relevant and will not become obsolete.

Clarity rating: 3

The text in the book is clear. Certain aspects of the text could have been presented more clearly. For example, the section on main effects and interactions are some concepts that students may have difficulty understanding. Those areas could be explained more clearly with an example.

Consistency rating: 3

Graphs in the book lacks titles and variable names. Also, the format of chapter title page needs to be consistent.

At times there were related topics spread across several chapters. This could be corrected for a better read by the audience..

The book text is very clear, and the flow from one topic to the next was adequate. However, having a outline would help the reader.

The PDF copy of the book was a easy read. There were few links that were missing though.

There were no grammatical errors.

The text is not offensive and examples in it are mostly based on historical US based experiments.

I would start of by saying that I am a supporter of the Open Textbook concept. In this day and age, there are a variety of Research Methods book/text available on the market. While this book covers research methods basics, it cannot be recommended in its current form as an acceptable alternative to the standard text. Modifications to the text as recommended by myself and other reviewers might improve the quality of this book in the future.

This text includes all important areas that are featured in other Research Methods textbooks and are presented in a logical order. The text includes great examples and provides the references which can be assigned as supplemental readings. In addition, the chapters end with exercises that can be completed in class or as part of a laboratory assignment. This text would be a great addition to a Research Methods course or an Introductory Statistics course for Psychology majors.

The content is accurate. I did not find any errors and the material is unbiased.

Yes - the content is up to date and would be easy to update if/when necessary.

The text is written at an appropriate level for undergraduate students and explains important terminology. The research studies that the author references are ones that undergraduate psychology majors should be familiar with. The only section that was questionable to me was that on multiple regression in section 8.3 (Complex Correlational Designs). I am unaware of other introductory Research Methods textbooks that cover this analysis, especially without describing simple regression first.

The text is consistent in terms of terminology. The framework is also consistent - the chapters begin with Learning Objectives and ends with Key Takeaways and Exercises.

The text is divisible into smaller reading sections - possibly too many. The sections are brief, and in some instances too brief (e.g., the section on qualitative research). I think that the section headers are helpful for instructors who plan on using this text in conjunction with another text in their course.

The topics were presented in a logical fashion and are similar to other published Research Methods texts. The writing is very clear and great examples are provided. I think that some of the sections are rather brief and more information and examples could be provided.

I did not see any interface issues. All of the links worked properly and the tables and figures were accurate and free of errors. I particularly liked the figures in section 5.2 on reliability of measurement.

There are three comments that I have about the interface, however. First, I was expecting the keywords in blue font to be linked to a glossary, but they were not. I would have appreciated this feature. Second, I read this text as a PDF on an iPad and this version lacking was the Table of Contents (TOC) feature. Although I was able to view the TOC in different versions, I would have appreciated it in the PDF version. Also, it would be nice if the TOC was clickable (i.e., you could click on a section and it automatically directed you to that section). Third, I think the reader of this text would benefit from a glossary at the end of each chapter and/or an index at the end of the text. The "Key Takeaways" sections at the end of each chapter were helpful, but I think that a glossary would be a nice addition as well.

I did not notice any grammatical errors of any kind. The text was easy to read and I think that undergraduate students would agree.

The text was not insensitive or offensive to any races, ethnicities, or backgrounds. I appreciated the section on avoiding biased language when writing manuscripts (e.g., using 'children with learning disabilities' instead of 'special children' or using 'African American' instead of 'minority').

I think that this text would be a nice addition to a Research Methods & Statistics course in psychology. There are some sections that I found particularly helpful: (1) 2.2 and 2.3 - the author gives detailed information about generating research questions and reviewing the literature; (2) 9.2 - this section focuses on constructing survey questionnaires; (3) 11.2 and 11.3 - the author talks about writing a research report and about presenting at conferences. These sections will be great additions to an undergraduate Research Methods course. The brief introduction to APA style was also helpful, but should be supplemented with the most recent APA style manual.

The sections in this textbook are overall more brief than in previous Methods texts that I have used. Sometimes this brevity is helpful in terms of getting to the point of the text and moving on. In other cases, some topics could use a bit more detail to establish a better foundation of the content before moving on to examples and/or the next topic.

I did not find any incorrect information or gross language issues.

Basic statistical and/or methodological texts tend to stay current and up-to-date because the topics in this field have not changed over the decades. Any updated methodologies would be found in a more advanced methods text.

The text is very clear and the ideas are easy to follow/ presented in a logical manner. The most helpful thing about this textbook is that the author arrives at the point of the topic very quickly. Another helpful point about this textbook is the relevancy of the examples used. The examples appear to be accessible to a wide audience and do not require specialization or previous knowledge of other fields of psychology.

I feel this text is very consistent throughout. The ideas build on each other and no terms are discussed in later chapters without being established in previous chapters.

Each chapter had multiple subsections which would allow for smaller reading sections throughout the course. The amount of content in each section and chapter appeared to be less than what I have encountered in other Methods texts.

The organization of the topics in this textbook follows the same or similar organization that I see in other textbooks. As I mentioned previously, the ideas build very well throughout the text.

I did not find any issues with navigation or distortion of the figures in the text.

There were not any obvious and/or egregious grammatical errors that I encountered in this text.

This topic is not really an issue with a Methods textbook as the topics are more so conceptual as opposed to topical. That being said, I did not see an issue with any examples used.

I have no other comments than what I addressed previously.

Mixed. For some topics, there is more (and more practical) information than in most textbooks. I appreciated the very practical advice to students about how to plot data (in statistics chapters). Similarly, there is practical advice about how to comply with ethical guidelines. The section on item development in surveys was very good.

On the other hand, there is far too little information about some subjects. For example, independent and dependent variables are introduced in passing in an early chapter and then referred to only much later in the text. In my experience, students have a surprisingly difficult time grasping this concept. Another important example is sampling; I would have preferred much more information on types of samples and sampling techniques, and the problems that arise from poor sampling. A third example is the introduction to basic experimental design. Variables, measurement, validity, and reliability are all introduced in one chapter.

I did not see an index or glossary.

I found no errors.

The fundamentals of research methods do not change much. Given the current replication crisis in psychology, it might be helpful to have something about replicability.

Mixed. The text itself is spare and clear. The style of the book is to explain a concept in very few words. There are some excellent aspects of this, but on the other hand, there are some concepts that students have a very difficult time undersatnding if they are not embedded in concrete examples. For example, the section on main effects and interactions shows bar graphs of interactions, but this is presented without variable names or axis titles, and separate from any specific experiment.

Sometimes the chapter stucture is laid out on the title page, and other times it is not. Some graphs lack titles and variable names.

The chapters can be stand alone, but sometimes I found conceptually similar pieces spread across several chapters, and conceptually different pieces in the same chapters.

The individual sentences and paragraphs are always very clear. However, I felt that more tables/outlines of major concepts would have been helpful. For example, perhaps a flow chart of different kinds of experimental designs would be useful. (See section on comprehensiveness for more about organization).

The flow from one topic to the next was adequate.

I read the pdf. Perhaps the interface is more pleasant on other devices, but I found the different formats and fonts in image/captions/main text/figure labels distracting. Many if the instances of apparently hyperlinked (blue) text to do not link to anything.

I found no grammatical errors, and prose is standard academic English.

Like most psychology textbooks available in the US, examples are focused on important experiments in US history.

I really wanted to be happy with this text. I am a supporter of the Open Textbook concept, and I wanted to find this book an acceptable alternative to the variety of Research Methods texts I’ve used. Unfortunately, I cannot recommend this book as superior in quality.

The text includes basic, essential information needed for students in an introductory research methods course. In addition, the text includes three chapters (i.e., research ethics, theory, and APA style) that are typically absent from or inadequately covered in similar texts. However, I did have some areas of concern regarding the coverage of qualitative and mixed methods approaches, and nonparametric tests. Although the author advocates for the research question to guide the choice of approach and design, minimal attention is given to the various qualitative designs (e.g., phenomenology, narrative, participatory action, etc.) beyond grounded theory and case studies, with no mention of the different types of mixed methods designs (e.g., concurrent, explanatory, exploratory) that are prevalent today. In addition, common nonparametric tests (e.g., Wilcoxon, Mann-Whitney, etc.) and parametric tests for categorical data (e.g., chi-square, Fisher’s exact, etc.) are not mentioned.

The text overall is accurate and free of errors. I noticed in the qualitative research sub-section, the author describes qualitative research in general, but does not mention common practices associated with qualitative research, such as transcribing interviews, coding data (e.g., different approaches to coding, different types of codes), and data analysis procedures. The information that is included appears accurate.

The text appears up-to-date and includes basic research information and classic examples that rarely change, which may allow the text to be used for many years. However, the author may want to add information about mixed methods research, a growing research approach, in order for the text to stay relevant across time.

The text includes clear, accessible, straightforward language with minimal jargon. When the author introduces a new term, the term is immediately defined and described. The author also provides interesting examples to clarify and expand understanding of terms and concepts throughout the text.

The text is internally consistent and uses similar language and vocabulary throughout. The author uses real-life examples across chapters in order to provide depth and insight into the information. In addition, the vocabulary, concepts, and organization are consistent with other research methods textbooks.

The modules are short, concise, and manageable for students; the material within each module is logically focused and related to each other. I may move the modules and the sub-topics within them into a slightly different order for my class, and add the information mentioned above, but overall, this is very good.

The author presents topics and structures chapters in a logical and organized manner. The epub and online version do not include page numbers in the text, but the pdf does; this may be confusing when referencing the text or answering student questions. The book ends somewhat abruptly after the chapter on inferential statistics; the text may benefit from a concluding chapter to bring everything together, perhaps with a culminating example that walks the reader through creating the research question, choosing a research approach/design, etc., all the way to writing the research report.

I used and compared the pdf, epub, and online versions of the text. The epub and online versions include a clickable table of contents, but the pdf does not. The table format is inconsistent across the three versions; in the epub version (viewed through ibooks), the table data does not always line up correctly, making it difficult to interpret quickly. In the pdf and online versions, the table format looks different, but the data are lined up. No index made it difficult to quickly find areas of interest in the text; however, I could use the Find/Search functions in all three versions to search and find needed items.

As I read through this text, I did not detect any glaring grammatical errors. Overall, I think the text is written quite well in a style that is accessible to students.

The author uses inclusive, person-first language, and the text does not seem to be offensive or insensitive. As I read, I did notice that topics such as diversity and cultural competency are absent.

I enjoyed reading this text and am very excited to have a free research methods text for my students that I may supplement as needed. I wish there was a test question bank and/or flashcards for my students to help them study, but perhaps that could be added in the future. Overall, this is a great resource!

The text covers all the areas and ideas of the subject of research methods in psychology for the learner that is just entering the field. The authors cover all of the content of an introductory research methods textbook and use exemplary examples that make those concepts relevent to a beginning researcher. As the authors state, the material is presented in such a manner as to encourage learners to not only be effective consumers of current research but also engage as critical thinkers in the many diverse situations one encounters in everyday life.

The content is accurate, error free, and unbiased. It explains both quantiative and qualitative methods in an unbiased manner. It is a bit slim on qualitative. It would be nice to have a bit more information on, for example, creating interview questions, coding, and qualitative data anaylisis.

The text is up to date, having just been revised. This revision was authored by Rajiv Jhangiani (Capilano University, North Vancouver) and includes the addition of a table of contents and cover page that the original text did not have, changes to Chapter 3 (Research Ethics) to include a contemporary example of an ethical breach and to reflect Canadian ethical guidelines and privacy laws, additional information regarding online data collection in Chapter 9 (Survey Research). Jhangiani has correcte of errors in the text and formulae, as well as changing spelling from US to Canadian conventions. The text is also now available in a inexpensive hard copy which students can purchase online or college bookstores can stock. This makes the text current and updates should be minimal.

The text is very easy to read and also very interesting as the authors supplement content with amazing real life examples.

The text is internally consistent in terms of terminology and framework.

This text is easily and readily divisible into smaller reading sections that can be assigned at different points within a course. I am going to use this text in conjunction with the OER OpenStax Psychology text for my Honors Psychology course. I currently use the OER Openstax Psychology textbook for my Positive Psychology course as well as my General Psychology course,

The topics in the text are presented in logical and clear fashion. The way they are presented allows the text to be used in conjuction with other textbooks as a secondary resource.

The text is free of significant interface issues. It is written in a manner that follows the natural process of doing research.

The text contained no noted grammatical errors.

The text is not culturally insensitive or offensive and actually has been revised to accomodate Canadian ethical guidelines as well as those of the APA.

I have to say that I am excited to have found this revised edition. My students will be so happy that there is also a reasonable priced hard coopy for them to purchase. They love the OpenStax Psychology text with the hard copy available from our bookstore. I do wish there were PowerPoints available for the text as well as a test bank. That is always a bonus!

This text covers everything I would consider essential for a first course in research methods, including some areas that are not consistently found in introductory texts (e.g., qualitative research, criticisms of null hypothesis significance testing). The chapters on ethics (Ch. 3) and theory (Ch. 4) are more comprehensive than most I have seen at this level, but not to the extent of information overload; rather, they anticipate and address many questions that undergraduates often have about these issues.

There is no index or table of contents provided in the PDF, and the table of contents on the website is very broad, but the material is well organized and it would not be hard for an instructor to create such a table. Chapter 2.1 is intended to be an introduction to several key terms and ideas (e.g., variable, correlation) that could serve as a sort of glossary.

I found the text to be highly accurate throughout; terms are defined precisely and correctly.

Where there are controversies or differences of opinion in the field, the author presents both sides of the argument in a respectful and unbiased manner. He explicitly discourages students from dismissing any one approach as inherently flawed, discussing not only the advantages and disadvantages of all methods (including nonexperimental ones) but also ways researchers address the disadvantages.

In several places, the textbook explicitly addresses the history and development of various methods (e.g., qualitative research, null hypothesis significance testing) and the ways in which researchers' views have changed. This allows the author to present current thinking and debate in these areas yet still expose students to older ideas they are likely to encounter as they read the research literature. I think this approach sets students up well to encounter future methodological advances; as a field, we refine our methods over time. I think the author could easily integrate new developments in future editions, or instructors could introduce such developments as supplementary material without creating confusion by contradicting the test.

The examples are generally drawn from classic psychological studies that have held up well over time; I think they will appeal to students for some time to come and not appear dated.

The only area in which I did not feel the content was entirely up to date was in the area of psychological measurement; Chapter 5.2 is based on the traditional view and not the more comprehensive modern or holistic view as presented in the 1999 AERA/APA Standards for Educational and Psychological Measurement. However, a comprehensive treatment of measurement validity is probably not necessary for most undergraduates at this stage, and they will certainly encounter the older framework in the research literature.

The textbook does an excellent job of presenting concepts in simple, accessible language without introducing error by oversimplification. The author consistently anticipates common points of confusion, clarifies terms, and even suggests ways for students to remember key distinctions. Terms are clearly and concretely defined when they are introduced. In contrast to many texts I have used, the terms that are highlighted in the text are actually the terms I would want my students to remember and study; the author refrains from using psychological jargon that is not central to the concepts he is discussing.

I noticed no major inconsistencies or gaps.

The division of sections within each chapter is useful; although I liked the overall organization of the text, there were points at which I would likely assign sections in a slightly different order and I felt I could do this easily without loss of continuity. The one place I would have liked more modularity was in the discussion of inferential statistics: t-tests, ANOVA, and Pearson's r are all covered within Chapter 13.2. On the one hand, this enables students to see the relationships and similarities among these tests, but on the other, this is a lot for students to take in at once.

I found the overall organization of the book to be quite logical, mirroring the sequence of steps a researcher would use to develop a research question, design a study, etc. As discussed above, the modularity of the book makes it easy to reorder sections to suit the structure of a particular class (for example, I might have students read the section on APA writing earlier in the semester as they begin drafting their own research proposals). I like the inclusion of ethics very early on in the text, establishing the importance of this topic for all research design choices.

One organizational feature I particularly appreciated was the consistent integration of conceptual and practical ideas; for example, in the discussion of psychological measurement, reliability and validity are discussed alongside the importance of giving clear instructions and making sure participants cannot be identified by their writing implements. This gives students an accurate and honest picture of the research process - some of the choices we make are driven by scientific ideals and some are driven by practical lessons learned. Students often have questions related to these mundane aspects of conducting research and it is helpful to have them so clearly addressed.

Although I didn't encounter any problems per se with the interface, I do think it could be made more user-friendly. For example, references to figures and tables are highlighted in blue, appearing to be hyperlinks, but they were not. Having such links, as well as a linked, easily-navigable and detailed table of contents, would also be helpful (and useful to students who use assistive technology).

I noticed no grammatical errors.

Where necessary, the author uses inclusive language and there is nothing that seems clearly offensive. The examples generally reflect American psychology research, but the focus is on the methods used and not the participants or cultural context. The text could be more intentionally or proactively inclusive, but it is not insensitive or exclusive.

I am generally hard to please when it comes to textbooks, but I found very little to quibble with in this one. It is a very well-written and accessible introduction to research methods that meets students where they are, addressing their common questions, misconceptions, and concerns. Although it's not flashy, the figures, graphics, and extra resources provided are clear, helpful, and relevant.

The text is thorough in terms of covering introductory concepts that are central to experimental and correlational/association designs. I find the general exclusion of qualitative and mixed methods designs hard to defend (despite some researchers’ distaste for the methods). While these approaches were less commonly used in the recent past, they are prevalent in the early years of psychology and are ascending once again. It strikes me as odd to just ignore two whole families of methods that are used within the practice of psychology—definitely not a sustainable approach.

I do very much appreciate the emphasis on those who will both practice and consume psychology, given the wide variety of undergraduate career paths.

One glaring omission is a Table of Contents within the PDF. It would be nice to make this a linked PDF, so that clicking on the entry in a TOC (or cross-references) would jump the reader to the relevant section.

I did not see an errors. The chapter on theory is not as clear as it could be. The section “what is theory” is not very clear, and these are difficulte concepts (difference between theory, hypothesis, etc.). A bit more time spent here could have been good. Also, the discussion of functional, mechanistic, and typological theories leaves out the fourth of Pepper’s metaphors: contextualism. I’m not sure that was intentional and accidental, but it is noticeable!

This is a research methods text focused on experimental and association designs. The basics of these designs do not change a whole lot over time, so there is little likelihood that the main content will become obsolete anytime soon. Some of the examples used are a bit dated, but then again most of them are considered “classics” in the field, which I think are important to retain (and there is at least one “new classic” included in the ethics section, namely the fraudulent research linking autism to the MMR vaccine).

The text is extremely clear and accessible. In fact, it may even be *too* simple for undergraduate use. Then again, students often struggle with methods, so simplicity is good, and the simplicity can also make the book marketable to high school courses (although I doubt many high schools have methods courses).

Yes, quite consistent throughout. Carrying through the same examples into different chapters is a major strength of the text.

I don’ anticipate any problems here.

The book flows well, with brief sections. I do wonder if maybe the sections are too brief? Perhaps too many check-ins? The “key take-aways” usually come after only a few pages. As mentioned above, the book is written at a very basic level, so this brevity is consistent with that approach. It is not a problem, per se, but those considering adopting the text should be aware of this aspect.

No problems here.

I did not detect any grammatical errors. The text flows very well.

The book is fairly typical of American research methods books in that it only focuses on the U.S. context and draws its examples from “mainstream” psychology (e.g., little inclusion of ethnic minority or cross-cultural psychology). However, the text is certainly not insensitive or offensive in any way.

Nice book, thanks for writing it!

The text is well organized and written, integrates excellent pedagogical features, and covers all of the traditional areas of the topic admirably. The final two chapters provide a good bridge between the research methods course and the follow-up course on behavioural statistics. The text integrates real psychological measures, harnesses students' existing knowledge from introductory psychology, includes well-chosen examples from real life and research, and even includes a very practical chapter on the use of APA style for writing and referencing. On the other hand, it does not include a table of contents or an index, both of which are highly desirable. The one chapter that requires significant revision is Chapter 3 (Research Ethics), which is based on the US codes of ethics (e.g., Federal policy & APA code) and does not include any mention of the Canadian Tri-Council Policy Statement.

The very few errors I found include the following: 1. The text should read "The fact that his F score…" instead of "The fact that his t score…" on page 364 2. Some formulae are missing the line that separates the numerator from the denominator. See pages 306, 311, 315, and 361 3. Table 12.3 on page 310 lists the variance as 288 when it is 28.8

The text is up-to-date and will not soon lose relevance. The only things I would add are a brief discussion of the contemporary case of Diederik Stapel's research fraud in the chapter on Research Ethics, as well as some research concerning the external validity of web-based studies (e.g., Gosling et al.'s 2004 article in American Psychologist).

Overall, the style of writing makes this text highly accessible. The writing flows well, is well organized, and includes excellent, detailed, and clear examples and explanations for concepts. The examples often build on concepts or theories students would have covered in their introductory psychology course. Some constructive criticism: 1. When discussing z scores on page 311 it might have been helpful to point out that the mean and SD for a set of calculated z scores are 0 and 1 respectively. Good students will come to this realization themselves, but it is not a bad thing to point it out nonetheless. 2. The introduction of the concept of multiple regression might be difficult for some students to grasp. 3. The only place where I felt short of an explanation was in the use of a research example to demonstrate the use of a line graph on page 318. In this case the explanation in question does not pertain to the line graph itself but the result of the study used, which is so fascinating that students will wish for the researchers' explanation for it.

The text is internally consistent.

The text is organized very well into chapters, modules within each chapter, and learning objectives within each module. Each module also includes useful exercises that help consolidate learning.

As mentioned earlier, the style of writing makes this text highly accessible. The writing flows well, is well organized, and includes excellent, detailed, and clear examples and explanations for concepts. The examples often build on concepts or theories students would have covered in their introductory psychology course. Only rarely did I feel that the author could have assisted the student by demonstrating the set-by-step calculation of a statistic (e.g., on page 322 for the calculation of Pearson's r)

The images, graphs, and charts are clear. The only serious issues that hamper navigation are the lack of a table of contents and an index. Many of the graphs will need to be printed in colour (or otherwise modified) for the students to follow the explanations provided in the text.

The text is written rather well and is free from grammatical errors. Of course, spellings are in the US convention.

The text is not culturally insensitive or offensive. Of course, it is not a Canadian edition and so many of the examples (all of which are easy to comprehend) come from a US context.

I have covered most of these issues in my earlier comments. The only things left to mention are that the author should have clearly distinguished between mundane and psychological realism, and that, in my opinion, the threats to internal validity could have been grouped together and might have been closer to an exhaustive list.

25 Most Influential Psychology Books 2010–2020

Psychology is the scientific study of the mind—primarily, the human mind, but also animal minds (comparative psychology). Understood as the study of human subjective consciousness, or the “soul” (psukhē, in Greek), psychology was for centuries an aspect of philosophy, with roots in such basic works of classical civilization as Plato’s Phaedo (early 4th c. BC), Aristotle’s On the Soul (c. 350 BC), and Augustine’s Confessions (c. 400 AD).

Key Takeaways

• The most influential psychology books featured on this list were chosen for their academic influence and popular impact on the field of psychology. Both the classic books and contemporary works on psychology and its specializations, such as evolutionary psychology, social psychology, and cognitive psychology, are featured.
• These psychology books also represent a wide spectrum of interests, from empirical research to real-life examples of the human experience. You can use these books to improve your own life and clinical practice for this reason.
• Keep in mind that many of these psychology books are their respective author’s life’s work and, thus, their views may be limited by their times (i.e., context).

A Brief History of the Field of Psychology

Slowly—over the course of several centuries following the Scientific Revolution and culminating in the nineteenth century—new scientific disciplines split off from psychology. Notable examples include the empirical study of human sensory capabilities (“psychophysics”) and the histology and physiology of the brain. During the twentieth century, these studies matured into the fields we now know as experimental psychology and neuroscience.

During the second half of the twentieth century, several new disciplines budded off from the main body of psychology. These disciplines—notably, psycholinguistics and cognitive science—attempt to understand human mentality from the point of view of logico-mathematical models that have nothing directly to do with the material (physiological) character of the brain. More particularly, cognitive science is based on the hypothesis of computationalism—a philosophy which holds that the mind stands in the same relation to the brain as computer software stands to hardware.

After shedding all of these daughter fields, psychology remains a vibrant field of research focused on the subjective mind. Today, the discipline of psychology consists of a wide variety of subfields, including clinical psychology, child psychology, developmental psychology, social psychology, evolutionary psychology, and many others.

One of the most important of these is clinical psychology, which is an applied field that attempts to alleviate the suffering of those with mental illnesses. Clinical psychology, or “psychotherapy,” is itself very broadly conceived, including a broad spectrum of different therapies. These go by such names as psychoanalysis, existential psychology, phenomenological psychology, humanistic psychology, cognitive-behavioral therapy, and a host of others.

With these considerations in mind, we have compiled a list of the most influential books in psychology over the past decade (2011–2021). We have assigned an objective measure of “influence” to each book on the basis of the number of references it has received in both the academic literature and the popular media.

Note that our list does not necessarily represent the most popular psychology books overall published during the past ten years, nor is it a straightforward list of psychology bestsellers during that time frame—for several reasons.

For one thing, we have excluded psychology textbooks and technical reference works, as well as sacred texts and fictional works which may contain related material.

Several of the works included on the list are classics in the field, dating to the early twentieth century. Nevertheless, ours is not a list of the most influential psychology books of all time. Such a list would have a very different look and feel to it.

Rather, our list provides you with the 25 books on psychology that have had the greatest combined academic and popular impact over the past decade.

Getting Your Hands On Must-read Published Books on Psychology

The most influential psychology books are popular among aspiring and practicing psychologists for the useful insights made by their authors. Their diverse subject matter, from the prehistoric origins of human sexuality to the psychology of evil, make for interesting reading, too. The classic work of C.G. Jung and Sigmung Freud complete the list of must-read psychology books.

Remember, however, that critical reading is crucial in getting the most from these psychology books! You will gain a better understanding of the cognitive, mental, and social processes involved in people’s reactions and relationships to others and to their environment.

Here are tips to get the most out of reading these influential psychology books:

Keep Your Clients/Patients in Mind

As an aspiring or practicing psychologist, you’re in the best position to make a positive difference in the lives of individuals and families. Your main concerns are their well-being, first and foremost, and their ability for self-awareness, self-knowledge, and self-regulation. In doing so, they are able to improve their human relationships and enjoy happiness in their everyday life.

You can then look for useful insights, methods and tips from the authors that you can apply in your own life and clinical practice. Take notes, too, if you can.

Increase Your Knowledge and Skills

Oftentimes, psychologists rely on the personal experiences of other individuals and professionals toward the improvement of their practice and profession. Many of these books were written based on first-person experiences and viewpoints, such as Sex at Dawn and Dreamseller: An Addiction Memoir . You will gain a better appreciation of the struggles that many of your clients/patients face in their lives by reading these accounts.

Of course, it’s always a great idea to return to the classics! The Collected Works of C.G. Jung and The Interpretation of Dreams by Sigmund Freud continue to have profound effects on contemporary psychology. You may even be able to find new topics for your scientific research—either to prove or disprove their theories, for example—from revisiting these books.

You can also share your newfound knowledge and insights, discuss classic theories, and explore research topics with your colleagues after reading these books. The windows to the human mind that these books provide are, indeed, invaluable to your own professional advancement and personal development.

Many of these books are also opportunities to expand your knowledge of applied science in psychology. You can take the existing body of knowledge presented in these books and apply them to contemporary theories. You will likely be able to assist patients with mental illnesses, for example, in their decision-making processes.

When reading these psychology books, you must remember that the authors have their own biases, too, based on their personal experiences and their specific periods. An open mind is then a must, but you should also keep in mind the contemporary body of knowledge in psychology.

In your readings, you must also remember that psychology is an ever-evolving field. You should keep the core ethics of the profession in mind, particularly integrity, fidelity and responsibility, and respect for people’s dignity and rights, at all times.

Read on for a look at The 25 Most Influential Books in Psychology.

25 Most Influential Books in Psychology

1. the righteous mind: why good people are divided by politics and religion.

By: Jonathan Haidt , 2012

Haidt (b. 1963) is a social psychologist at New York University. His research is focused on the social context and sources of individual happiness, and related topics. One of his principal claims is that morality is shaped by emotion and intuition more than by reasoning.

The book under consideration here explores some of the ways in which differing notions of right and wrong affect people’s political opinions and allegiances.

His conclusion is that one of the main reasons for disagreement between political conservatives and liberals is the different ways in which they understand the claims of morality. Haidt identifies five separate dimensions of moral thinking, namely:

• Fairness/Reciprocity
• In-Group/Loyalty
• Authority/Respect
• Purity/Sanctity

He then observes that liberals typically only acknowledge moral claims lying within the first two dimensions, whereas conservatives recognize moral claims from all five dimensions. For this reason, Haidt calls liberals “two-channel” moral thinkers and conservatives “five-channel” moral thinkers.

2. Sex at Dawn: The Prehistoric Origins of Modern Sexuality

By: Christopher Ryan and Cacilda Jetha, 2010

Freelance psychologist Ryan (b. 1962) and psychiatrist Jethá (age unknown) are a married couple who boast of having an “open” marriage. One might say that this book is a polemical review of the paleontological and anthropological literatures whose purpose is to give their personal sexual tastes the imprimatur of cutting-edge evolutionary psychology.

Evolutionary psychology is a field which endeavors to reconstruct the “environment of evolutionary adaptedness” (EEA) of the human species. The idea is that “natural” human behavior can be read directly off the primatological and ethnographic evidence. Then, it is claimed that the unhappiness of modern humans is due to the distortion of our natural instincts by the social structures of civilization. In this way, human “liberation” consists in throwing off the restraints of civilization and returning to the prehistoric social structures which conform better to our EEA instincts.

More specifically, this book maintains that “polyamory” is the default setting of human sexuality in the EEA, and that the institution of monogamy is both a corruption of our natural proclivity for sexual promiscuity and a primary source of human suffering. Sigmund Freud (see #16 below) argued along similar lines long ago, and one might argue that this book’s main objective is to substitute the putative scientific authority of Darwin for the now-tarnished reputation of Freud.

Sex at Dawn was republished in 2011 with a new subtitle: How We Mate, Why We Stray, and What It Means for Modern Relationships .

3. Mastermind: How to Think Like Sherlock Holmes

By: Maria Konnikova , 2013

Konnikova (b. 1984) is a Russian-born psychologist, author, and podcaster. In earlier work, she applied her knowledge of psychology to the analysis of confidence artists and poker players, and to exploring such related topics as trust, misdirection, bluffing, strategy, and games of chance.

The book under discussion here uses a beloved fictional character—the master detective Sherlock Holmes created by British author Arthur Conan Doyle (1859–1930)—as a means for exploring such subjects as empirical observation and logical thinking. Holmes, who first appeared in Conan Doyle’s 1887 novel, A Study in Scarlet , was the protagonist of three more novels and 56 short stories published by Conan Doyle over four decades up through 1927.

Konnikova distinguishes what she calls Holmes’s “habits of mind” and shows how they interrelate with findings from the modern-day fields of psychology and neuroscience. These include inquisitiveness, mindfulness, restraint, and seeking objective evidence no matter whether it confirms or refutes one’s prior beliefs.

Konnikova also maintains that these habits need to be supplemented with what she calls a “a healthy dose of skepticism”—basically, a willingness to question everything one believes. If one imitates Sherlock Holmes in all these respects, she argues, then one may become a more rational thinker.

4. The Lucifer Effect: Understanding How Good People Turn Evil

By: Philip Zimbardo , 2007

Zimbardo (b. 1933) is a psychologist at Stanford University. He is primarily known for the so-called “Stanford prison experiment” that he conducted with the participation of Stanford student volunteers in 1971. The book under consideration here is fundamentally an explanation of the results and a consideration of the many implications of that famous experiment.

The set-up for the Stanford prison experiment was as follows: a group of college students were randomly assigned to two subgroups. One group was designated as “guards” and the other group as “inmates.” Then, a mock-prison environment was created and each sub-group was tasked with playing out its prescribed role within that environment.

The experiment was more “successful” than Zimbardo could have imagined. Having internalized the idea that their actions were implicitly sanctioned by authority, the “guards” quickly began to exert more and more force on the “inmates,” amounting to what would have been torture in a real-life situation and leading to an emotional breakdown on the part of one student-inmate, who had to be removed from the study. The entire experiment had to be shut down ahead of schedule to avoid even worse consequences.

In this book, Zimbardo also applies the lessons he feels were learned from his 1971 experiment to other situations, notably, the abuses that occurred at the American-run Iraqi prison, Abu Ghraib, in 2004.

In summary, Zimbardo believes that his 1971 Stanford study shows that “situations can have a more powerful influence over our behavior than most people appreciate.” He has also stated that we ought to stop thinking of cases of abuse of authority in terms of “bad apples,” and begin thinking of them instead in terms of “bad barrels”—that is, institutions—that spoil the good apples within them.

5. Quiet: The Power of Introverts in a World That Can’t Stop Talking

By: Susan Cain , 2012

Cain (b. 1968) is a lawyer and author. She has been on the faculty of the Woodhull Institute for Ethical Leadership, which trains women for leadership roles in business and the professions. She has also delivered many lectures on the psychology of introverts, including several TED talks.

Cain is best known for the book under discussion here. A separate version of the book for the benefit of teenagers and their parents appeared in 2013 under the title, Quiet Power: The Secret Strengths of Introverts .

Cain’s principal thesis is that the psychological characteristics typically associated with introverted personality types, especially creativity, are valuable to society. Therefore, introversion should not be considered pathological, but rather ought to be valued and accommodated by the institutions of an extrovert-dominated mainstream society, especially in the public schools.

6. The Blank Slate: The Modern Denial of Human Nature

By: Steven Pinker , 2002

Pinker (b. 1954) is a cognitive scientist, linguist, and author. He is a well-known advocate of both evolutionary psychology and the computational theory of the mind. Pinker is currently Johnstone Family Professor of Psychology at Harvard University.

Among Pinker’s many bestselling popular science books (see #18 below), the one under consideration here is perhaps of the greatest psychological and philosophical significance. Its thesis is very simple to state: the concept of the blank slate (tabula rasa) is no longer tenable in the light of modern science. The implications of this idea, however, are profound.

“Tabula rasa” means “a writing-tablet wiped clean” in Latin. The term is most closely associated with the English philosopher, John Locke (1632–1704). It expresses the idea that human beings are born without any significant inborn instincts or propensities. It is equivalent to the idea that education and the social environment more broadly are what determine a person’s psychological characteristics, not his or her genetic or biological endowment. In other words, “blank slate” takes the “nurture” side of the “nature/nurture” controversy.

Pinker’s book does several things. First, it presents a powerful scientific case for the impact that biology has on human personality—and thus for the falsity of the blank-slate hypothesis.

Second, the book explores the manifold ramifications of accepting the false blank-slate model of human personality and behavior, from utopian social engineering, to releasing hardened criminals back into society, to blaming parents for all the psychological difficulties faced by their children.

In short, Pinker believes that effective intervention in human affairs, whether in the form of psychotherapy or of political action, presupposes a realistic view of the biological roots underlying human nature-and as such, serves as a rejection of the blank slate theory.

7. The Bell Curve: Intelligence and Class Structure in American Life

By: Richard Herrnstein and Charles Murray , 1994

Herrnstein (1930–1994) was a psychologist at Harvard University, while Murray (b. 1943) is a political scientist and freelance author, who since 1990 has been a scholar with the American Enterprise Institute.

The book under consideration here marshals a wealth of empirical data to support the authors’ main thesis: that innate intelligence (as measured by IQ tests) is a good predictor of success in life (as measured by employment status, income level, marriage status, avoidance of crime, addiction, mental illness, etc.).

The claim that IQ may be represented by a normal distribution (bell curve) and the claim that innate intelligence makes some contribution to life success are in themselves difficult to dispute. However, the book became exceedingly controversial for its claims regarding the relationship between race and IQ.

Among these were the claim that different IQ distributions for different racial groups are centered upon different mean values (that is, the bell curves for different groups do not line up perfectly), as well as the claim that this difference in intergroup mean IQ values may partly explain intergroup differences in life outcomes.

The latter claim, especially, has been denounced by many observers as not only scientifically unsupported, but as inherently racist. Herrnstein died just as the book was being published, but Murray has been emphatic that the authors never denied the importance of the influence of environment upon human life outcomes and that their empirical claims about IQ should be viewed as only one factor among many.

8. Thinking, Fast and Slow

By: Daniel Kahneman , 2011

Born in Mandatory Palestine and raised in Paris and in Israel, Kahneman (b. 1934) is today a professor of psychology at Princeton University. One of the founders of the discipline of behavioral economics, in 2002 he received the Nobel Prize for Economics.

This book is a summary statement of his life’s work and is written for a broad, educated audience. Behavioral economics is too large a subject to fully encapsulate here, but perhaps its central claim is that traditional economics, which assumes that human beings are purely rational agents, has failed to take “irrational” motivations properly into account. In this book, the author contextualizes this fundamental principle within the framework of evolutionary biology.

The book’s basic idea is that human beings possess two separate but parallel cognitive systems. One of these, the “slow” system, relies upon deductive reasoning, thus conforming more closely to the traditional economist’s view of human nature.

The other system, the “fast” one, is a set of cognitive abilities that we have inherited from our primate ancestors, which provide quick responses to situations critical for survival in which time is of the essence. Such responses are sometimes known as “judgments under uncertainty.” These fast cognitive systems latch onto environmental regularities which provide an organism with inductive rules-of-thumb to act upon in lieu of deductive reasoning.

9. The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom

By: Jonathan Haidt , 2006

This book is the first one that psychologist Haidt (see #1 above) wrote for a popular audience. It proved to be equally popular with academic reviewers and ordinary readers.

The structure of the book is well summarized by its subtitle: Haidt basically compares some of the most important findings of contemporary psychology with many of the precepts of the ancient wisdom traditions, as embodied in the teachings of the Buddha, Socrates, Jesus, and others.

His conclusion is that the two traditions, ancient and modern, complement each other well, particularly in relation to such profound aspects of human experience as happiness, virtue, purpose, and meaning.

The book has 10 substantive chapters, each of which examines one theme treated by modern psychology and ancient wisdom traditions, namely:

• Dimensions of the self
• How we change our minds
• Reciprocity
• Blaming others

10. Predictably Irrational: The Hidden Forces That Shape Our Decisions

By: Dan Ariely , 2008

Ariely (b. 1967) was born in New York City to Israeli parents, who returned to Israel when Dan was three. Thus, Ariely was raised in Israel, in the town of Ramat HaSharon, and earned his bachelor’s degree in psychology from Tel Aviv University.

He attended the University of North Carolina at Chapel Hill for graduate school, taking a PhD in cognitive psychology in 1996. Later, Ariely completed a second doctorate (in economics) at Duke University under the supervision of the founder of behavioral economics and economics Nobelis, Daniel Kahneman (see #8 above). Today, he is the James B. Duke Professor of Psychology and Behavioral Economics at Duke University.

In addition to having published numerous academic articles and seven books for a popular audience, Ariely has given several TED talks which together have received more than 15 million views.

The book under consideration here is an attempt to make some of the basic findings of behavioral economics accessible to the general reader. More specifically, the book aims to arm readers with knowledge of some of the subconscious motivations driving much of human behavior so that they can better bring them under conscious control. In this way, readers will be able to avoid procrastination, make better decisions, and in general better achieve their goals.

A revised and expanded edition of the book was published in 2010.

11. The Coddling of the American Mind: How Good Intentions and Bad Ideas Are Setting Up a Generation for Failure

By: Greg Lukianoff and Jonathan Haidt , 2019

Lukianoff (b. 1974) is a lawyer who in 1999 established the Foundation for Individual Rights in Education (FIRE) to protect the first-amendment rights of college students. Together with celebrity psychologist Haidt (see #1 and #9 above), in 2015 he penned an essay with the same title as this book in The Atlantic magazine. The book is basically an expansion of that essay.

The title of the essay and the book is an allusion to the similarly themed book, The Closing of the American Mind: How Higher Education Has Failed Democracy and Impoverished the Souls of Today’s Students , published in 1987 by University of Chicago philosopher, Allan Bloom (1930–1992).

The basic claim of Lukianoff and Haidt is that the recent introduction of “safe spaces,” “trigger warnings,” and similar concepts aimed at protecting America’s college students from confronting any ideas that might hurt their feelings by challenging their worldview is killing higher education in the U.S.

The authors’ argument is that free and open intellectual debate is the raison d’être and life’s blood of a university. They argue that no institution which systematically closes itself off from rational criticism can qualify as a worthy heir of the distinguished, nearly thousand-year-old tradition of Academia.

12. Willpower: Rediscovering the Greatest Human Strength

By: Roy Baumeister and John Tierney , 2011

Baumeister (b. 1953) is an American-born social psychologist currently teaching at the University of Queensland in Brisbane, Australia. Tierney (b. 1953) is a journalist and author specializing in reporting on science and related issues. Baumeister is the author, co-author, or co-editor of some 30 volumes of academic and popular writings.

Baumeister’s wide-ranging work touches on topics from self, sexuality, belonging, and social rejection, to self-esteem, self-control, motivation, aggression, and self-defeating behaviors, to consciousness and free will.

Baumeister is perhaps best known for his theory of “ego depletion,” which hypothesizes that there is a finite amount of mental energy available to drive willpower in the exertion of self-control.

A major topic of this book is a spectrum of therapies devised on the basis of the author’s ego depletion theory by Baumeister himself and others. This discussion explores various methods of husbanding mental energy in order to strengthen the willpower necessary to exercise self-control—which Baumeister sees as the “greatest human strength.”

13. Anatomy of an Epidemic: Magic Bullets, Psychiatric Drugs, and the Astonishing Rise of Mental Illness in America

By: Robert Whitaker , 2010

Whitaker (b. 1952) is a science journalist and author. Of his five published books, three are on the topic of psychiatry and mental illness.

The book under consideration here takes as its point of departure the following information unearthed by Whitaker: the number of persons declared officially disabled due to mental illness by the US government (and thus eligible to receive federal disability checks) approximately doubled during the 23 years between 1987 and 2010 (the year of the book’s publication). Whitaker says that he wrote this book in an effort to discover the reason behind this striking fact.

More specifically, the author considers several different theories that have been advanced, such as the dismantling of mental wards and hospitals and the invention of more-effective antipsychotic drugs. He shows that upon close examination the facts do not support these theories.

Whitaker concludes that the huge increase in mental illness in America at the end of the twentieth and beginning of the twenty-first centuries may be due to iatrogenic effects of the new drugs themselves—a claim that has been extremely controversial.

The author maintains a website, madinamerica.com, to provide interested readers access to the original data upon which his research and conclusions were based.

14. Character Strengths and Virtues: A Handbook and Classification

By: Christopher Peterson and Martin Seligman , 2004

This book is an academic handbook authored by two prominent leaders in the field of positive psychology—that is, the psychology of optimism, mental health, character, and well-being.

In its publicity for this book, the publisher has stated that, just as the Diagnostic and Statistical Manual of Mental Disorders (DSM) assesses and facilitates research on mental disorders, Character Strengths and Virtues provides a theoretical framework for understanding and developing therapeutic applications in the field of positive psychology.

Peterson (1950–2012) was a professor of psychology at the University of Michigan at Ann Arbor, where he was formerly chair of the clinical psychology department. He is one of the founders of the relatively recent sub-discipline of positive psychology.

In addition to the book under consideration here written with Seligman, Peterson has authored a textbook, A Primer in Positive Psychology (2006), and co-authored a popular book on positive psychology, as well as a two-volume history of psychology.

Seligman (b. 1942) is Zellerbach Family Professor of Psychology in the University of Pennsylvania’s Department of Psychology. He is also an expert in the field of positive psychology and is probably best known for his concept of “learned helplessness.” In addition to the volume discussed here, he has published six books for a popular audience.

This book advances a taxonomy developed by the authors, which identifies 24 measurable “character strengths” necessary for mental health, which are in turn organized into six classes of “core virtues”: namely, wisdom, courage, humanity, justice, temperance, and transcendence.

15. Why We Love Dogs, Eat Pigs, and Wear Cows: An Introduction to Carnism

By: Melanie Joy , 2009

Joy (b. 1966) is a former professor of psychology and sociology at the University of Massachusetts Boston. Joy resigned her academic position to devote her attention full-time to writing and vegan activism. In addition to this book, Joy is the author or co-author of five other volumes on veganism, “carnism” (meat-eating), and other issues.

The author also co-founded, in 2010, the vegan activist website, Beyond Carnism, previously known as the Carnism Awareness and Action Network.

Joy’s basic thesis is that human beings do not require meat for nourishment; therefore, we are not carnivores by biological necessity, but rather by choice.

She also points to the inconsistency between the way we lavish love and care on some animals (dogs, cats, etc.), while treating other animals (pigs, cows, and others) which possess the same capacity for joy and suffering with (as she sees it) great callousness and cruelty. For these psychological and moral reasons, Joy argues, we both can and should choose to renounce the consumption of meat.

The author’s most-recent book is The Vegan Matrix: Understanding and Discussing Privilege Among Vegans to Build a More Inclusive and Empowered Movement (2020).

16. The Interpretation of Dreams

By: Sigmund Freud , 1899

Freud (1856–1939) was, of course, one of the most famous and important thinkers of the past century. Born in Freiberg, Austria (now Příbor, Czech Republic), into a middle-class Jewish family, he pursued courses in biology and medicine at the University of Vienna. There, he studied philosophy with Franz Brentano (1838–1913) and physiology with Ernst Wilhelm von Brücke (1819–1892), eventually spending six years working in Brücke’s laboratory on the comparative anatomy and physiology of human, vertebrate, and invertebrate brains. He received his MD degree in 1881.

After a period working in Vienna General Hospital, in 1885 Freud spent a short fellowship at the Pitié-Salpêtrière Hospital in Paris working with the neurologist, Jean-Martin Charcot (1825–1893), a pioneer in the therapeutic use of hypnosis. The following year, he established a private practice in Vienna, concentrating on female patients exhibiting symptoms of what was then known as “hysteria” (neurosis).

Beginning with his second book, Studies on Hysteria (1895), co-authored with the physician and physiologist, Josef Breuer (1842–1925), Freud began to develop his elaborate theory of the human psyche in terms of three fundamental forces reified as the Ich (the “I,” or “ego”), the Es (the “it,” or “id”), and the Über-Ich (the “over-I,” or “superego”). Freud also proposed the idea that mental illness is mainly caused by sexual repression, and pioneered the “talking cure” therapy we have come to know as “psychoanalysis.”

All of this was elaborated in a series of important monographs published by Freud over the next 40-odd years, notably, the 1899 book under discussion here, as well as The Psychopathology of Everyday Life (1904), Three Essays on the Theory of Sexuality (1905), Totem and Taboo (1913), Beyond the Pleasure Principle (1920), The Ego and the Id (1923), The Future of an Illusion (1927), Civilization and Its Discontents (1930), and Moses and Monotheism (1939). The Interpretation of Dreams (Die Traumdeutung) concentrates on the putative meaning of dreams in terms of Freud’s theory and on the use of such interpretations in psychoanalytic therapy.

This book was first translated into English in 1913 by Viennese-born psychoanalyst, Abraham Brill (1874–1948). Another translation, which has become standard, was published in 1953 as volume V of the Standard Edition of the Complete Psychological Works of Sigmund Freud , under the general editorship of the British psychoanalyst, James Strachey (1887–1967). This edition has been reprinted numerous times.

17. Mindhunter: Inside the FBI’s Elite Serial Crime Unit

By: John E. Douglas and Mark Olshaker , 1995

Douglas (b. 1945) is a retired special agent with the US Federal Bureau of Investigation (FBI). Olshaker (b. 1951) is a professional writer.

This book—which is the basis for a popular TV series, which ran for two seasons in 2017 and 2019—recounts Douglas’s 25 years of experience in tracking and studying serial killers and mass murderers.

On the basis of decades of personal interviews with captured serial killers and others, the author developed a special “criminal-personality profile” to help law-enforcement officials better understand the thinking of such men so as to more effectively track them down and thwart their crime sprees.

The book provides disturbing portraits of several more recent serial killers, who have become famous through the reporting of the media. These include the Atlanta child murderer, Wayne Williams; the California serial rapist and killer, Edmund Kemper; the Anchorage, Alaska, serial killer, Robert Hansen; and the South Carolina killer, Larry Gene Bell.

The book was reprinted in 2017.

18. How the Mind Works

By: Steven Pinker , 1997

Pinker (see #6 above) is the author or editor of some 15 academic and popular volumes. The book under consideration here is the second of his books aimed at a general audience.

As a cognitive scientist and linguist, Pinker has a view of the mind known as “computationalism,” which posits a close analogy between the human mind and the computer such that the mind is to the brain as software is to hardware.

In addition, Pinker is also an enthusiastic proponent of “evolutionary psychology,” a relatively new psychological sub-discipline which attempts to explain aspects of contemporary human behavior in terms of the “selection advantage” of the behavior in the context of our “environment of evolutionary adaptedness” (EEA) during the Pleistocene epoch (see also #2 above).

This book is basically an attempt to demonstrate how these two seemingly disparate theories of the human mind—computationalism and evolutionary psychology—may be understood as complementary.

A fluent and prolific writer, Pinker is able to explain this dovetailing in terms accessible to a broad, popular readership.

19. The Varieties of Religious Experience: A Study in Human Nature

By: William James , 1902

James (1842–1910) was a professor of psychology and philosophy at Harvard University. Brother of the great novelist Henry James (1843–1916), William James was also one of the founders of the American school of philosophy known as “Pragmatism.”

James’s first significant book was his Principles of Psychology , published in 1890 in two volumes. This ground-breaking work summarizes the scientific advances in the understanding of the human mind made by the end of the nineteenth century, in a manner accessible to a broad, educated audience. James possessed a superb writing style, making him one of the most readable first-rate thinkers in the entire history of philosophy.

James insisted on paying attention to subjective or lived experience, in addition to the objective findings of the empirical science of his day. In this way, he may be considered a pioneer of the phenomenological movement, which was being developed at the same time by Franz Brentano (1838–1913), Edmund Husserl (1859–1938), and others.

Though James was a cutting-edge scientist, and by no means an orthodox theist, he maintained (controversially, but in line with his Pragmatist philosophy) that beliefs should be judged according to their “cash value” (i.e., the value they hold for the believer). Accordingly, he took religions seriously as human institutions and as valid belief systems.

The book under consideration here is a careful and scholarly—and extremely interesting—description and analysis of a wide range of historical religions and other religious phenomena. The book was derived from the Gifford Lectures for 1901–1902, which James was invited to deliver at the University of Edinburgh.

The book has been reprinted numerous times.

20. Man’s Search for Meaning

By: Viktor Frankl , 1946

Frankl (1905–1997) was an Austrian-born neurologist and psychologist. After receiving his MD in 1930, he worked at the Steinhof Psychiatric Hospital in Vienna, where he specialized in treating suicidal women.

In 1942, Frankl and his family, who were Jewish, were initially deported to the Theresienstadt concentration camp, where his father died of starvation. Subsequently, the surviving family members were sent to Auschwitz, where Frankl’s mother and brother were gassed. His wife later died of typhus in Bergen-Belsen. Frankl himself spent a total of three years in four different concentration camps.

After the war, Frankl returned to the University of Vienna as a graduate student, where he earned a PhD in philosophy in 1948. Eventually, he became a professor of neurology and psychiatry at the University of Vienna. He also held visiting professorships at Harvard University and elsewhere in the US.

Frankl is perhaps best known for his development of a form of humanist or “existential” psychotherapy he called “logotherapy,” which places emphasis on the importance of meaning and purpose for a balanced life and a healthy mind.

Frankl published 39 academic and popular volumes. The book under consideration here was originally published in 1946 as ...trotzdem Ja zum Leben sagen: Ein Psychologe erlebt das Konzentrationslager [In spite of everything, saying Yes to life: A psychologist experiences the concentration camp].

The book was translated into English in the same year. It has often been reprinted.

21. The Collected Works of C.G. Jung

By: Carl Jung , 1953–1980

Jung (1875–1961) was a Swiss psychiatrist and psychoanalyst. He studied medicine at the University of Zurich, then worked at the Burghölzli psychiatric hospital in Zurich. After studying in Paris with pioneering French psychologist, Pierre Janet (1859–1947), Jung obtained a teaching position at the University of Zurich, where he once again occupied a position with the Burghölzli.

Shortly after 1900, during his first stay at the Burghölzli, Jung (pronounced “Yoong”) met the psychiatrist Eugen Bleuler (1857–1939), who was already in touch with Sigmund Freud (see #16 above). This led to a correspondence and later a close collaboration and friendship between the young Jung and the older man.

At first, Jung was clearly a sort of disciple of the founder of psychoanalysis. However, with time, he began to develop a set of distinctive concepts, which went far beyond anything Freud had suggested. Perhaps the most famous of these was Jung’s notion of the “collective unconscious,” which takes the Freudian idea of the unconscious and projects it onto the human species as a whole.

Similar Jungian ideas include “archetype,” “persona,” and “shadow.” He also invented the concepts of “extroversion” and “introversion.” Jung also had a strong interest in what are now known as “paranormal” phenomena.

These typically Jungian teachings, which were heterodox from Freud’s point of view, eventually led to a break between the two men.

Jung was a prolific writer. His writings have been published in a uniform set of 20 volumes, plus eight supplementary volumes, known as the Collected Works . This edition was published gradually over a period of almost 30 years between 1953 and 1980. Many of the individual volumes are monographs which have appeared in other editions, as well.

22. The Honest Truth about Dishonesty: How We Lie to Everyone—Especially Ourselves

By: Dan Ariely , 2012

In this book, Ariely (see #10 above) applies the findings of behavioral economics pioneered by his mentor, Daniel Kahneman (see #8 above), to the problem of lying, cheating, fraud, and other forms of dishonesty.

The book recounts both scientific experiments conducted by Ariely and others, as well as personal anecdotes, which throw light on how people conduct themselves with respect to honesty/dishonesty under a variety of different social circumstances. Ariely’s main findings are (a) that minor infractions of honesty are extremely common, if not ubiquitous; and (b) that one of the main factors influencing such infractions is the availability of rationalization.

For example, the author arranged to have both dollar bills and cans of soda left lying around a dormitory common area. It turns out, perhaps counterintuitively, that more people helped themselves (i.e., stole) to the sodas than the dollar bills.

Ariely concluded that the explanation for this finding is that the thieves were better able to convince themselves that taking the sodas was not “really” stealing—something that they could not plausibly have done with respect to the paper currency.

23. The Sexual Paradox: Men, Women and the Real Gender Gap

By: Susan Pinker , 2008

Pinker (b. 1957) is a former clinical psychologist, Wall Street Journal social-science columnist, and author. She is the sister of Steven Pinker (see #6 and #18 above).

The “paradox” mentioned in the title of this book refers to the discrepancy between (a) the fact that women as a group generally do better in school than men at all levels; and (b) the fact that men are still disproportionately represented in the upper echelons of most professions (the “gender gap”).

After reviewing the evidence for both of these well-known facts, Pinker then considers various theories that have been advanced to explain the paradox. In conclusion, she rejects the notion that systemic discrimination is the main explanation.

Rather, in the apt words of one of the book’s reviewers, she “posit[s] the idea that women don’t have the same preferences as men and therefore, might actually choose different paths, not be forced into them by the patriarchy.”

24. Dreamseller: An Addiction Memoir

By: Brandon Novak and Joe Frantz , 2008

Novak (b. 1978) is a professional skateboarder, Jackass series stunt performer, pornographic film actor, CKY crew member, author, and motivational speaker. Frantz (b. 1977) is a filmmaker, author, and podcast host.

The book under consideration is a memoir which recounts Novak’s struggles with drug addiction. Among other things, it describes his downward spiral into drug use—culminating with heroin addiction—attempted suicide, and institutionalization in mental hospitals.

In addition to co-writing the book, Frantz also created a 2009 documentary film based on the memoir: Dreamseller: The Brandon Novak Documentary .

After the appearance of the book and the film, Novak relapsed and started using heroin again. This time he was arrested, spent 10 months in prison, and later, on probation. He has been clean since 2015.

25. In a Different Voice: Psychological Theory and Women’s Development

By: Carol Gilligan , 1982

Gilligan (b. 1936) received her PhD in social psychology from Harvard University, where she wrote her dissertation, “Responses to Temptation: An Analysis of Motives,” under the supervision of Lawrence Kohlberg (1927–1967), who is best known for his six-stage theory of moral development in children. Today, she is professor of Humanities and Applied Psychology at New York University.

Gilligan first came to the attention of the academic world through a series of academic papers critiquing Kohlberg’s work as male-biased and of limited applicability to females.

The book under the consideration here summarizes Gilligan’s work for a broad, intellectual readership. In it, the author recounts three major empirical studies that she pursued over several years. In these studies, she employed questionnaires to elicit the reasoning that her female subjects used in thinking through the three different moral dilemmas. Gilligan concludes that, while the women’s reasoning was immature according to Kohlberg’s criteria, such an inference from the data is profoundly unfair to women.

Instead, Gilligan argues that the empirical data support an entirely different conclusion—namely, that women and men are different kinds of moral reasoners. Whereas men typically employ abstract logical reasoning in thinking about difficult moral cases, women typically reason in terms of an ethics of caring that is primarily directed towards the needs of all the persons involved in such cases.

This ground-breaking book was reprinted with a new preface by the author in 2016.

2.2 Approaches to Research

Learning objectives.

By the end of this section, you will be able to:

• Describe the different research methods used by psychologists
• Discuss the strengths and weaknesses of case studies, naturalistic observation, surveys, and archival research
• Compare longitudinal and cross-sectional approaches to research
• Compare and contrast correlation and causation

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it. Some methods rely on observational techniques. Other approaches involve interactions between the researcher and the individuals who are being studied—ranging from a series of simple questions to extensive, in-depth interviews—to well-controlled experiments.

Each of these research methods has unique strengths and weaknesses, and each method may only be appropriate for certain types of research questions. For example, studies that rely primarily on observation produce incredible amounts of information, but the ability to apply this information to the larger population is somewhat limited because of small sample sizes. Survey research, on the other hand, allows researchers to easily collect data from relatively large samples. While this allows for results to be generalized to the larger population more easily, the information that can be collected on any given survey is somewhat limited and subject to problems associated with any type of self-reported data. Some researchers conduct archival research by using existing records. While this can be a fairly inexpensive way to collect data that can provide insight into a number of research questions, researchers using this approach have no control on how or what kind of data was collected. All of the methods described thus far are correlational in nature. This means that researchers can speak to important relationships that might exist between two or more variables of interest. However, correlational data cannot be used to make claims about cause-and-effect relationships.

Correlational research can find a relationship between two variables, but the only way a researcher can claim that the relationship between the variables is cause and effect is to perform an experiment. In experimental research, which will be discussed later in this chapter, there is a tremendous amount of control over variables of interest. While this is a powerful approach, experiments are often conducted in artificial settings. This calls into question the validity of experimental findings with regard to how they would apply in real-world settings. In addition, many of the questions that psychologists would like to answer cannot be pursued through experimental research because of ethical concerns.

Clinical or Case Studies

In 2011, the New York Times published a feature story on Krista and Tatiana Hogan, Canadian twin girls. These particular twins are unique because Krista and Tatiana are conjoined twins, connected at the head. There is evidence that the two girls are connected in a part of the brain called the thalamus, which is a major sensory relay center. Most incoming sensory information is sent through the thalamus before reaching higher regions of the cerebral cortex for processing.

Link to Learning

Watch this CBC video about Krista's and Tatiana's lives to learn more.

The implications of this potential connection mean that it might be possible for one twin to experience the sensations of the other twin. For instance, if Krista is watching a particularly funny television program, Tatiana might smile or laugh even if she is not watching the program. This particular possibility has piqued the interest of many neuroscientists who seek to understand how the brain uses sensory information.

These twins represent an enormous resource in the study of the brain, and since their condition is very rare, it is likely that as long as their family agrees, scientists will follow these girls very closely throughout their lives to gain as much information as possible (Dominus, 2011).

Over time, it has become clear that while Krista and Tatiana share some sensory experiences and motor control, they remain two distinct individuals, which provides invaluable insight for researchers interested in the mind and the brain (Egnor, 2017).

In observational research, scientists are conducting a clinical or case study when they focus on one person or just a few individuals. Indeed, some scientists spend their entire careers studying just 10–20 individuals. Why would they do this? Obviously, when they focus their attention on a very small number of people, they can gain a precious amount of insight into those cases. The richness of information that is collected in clinical or case studies is unmatched by any other single research method. This allows the researcher to have a very deep understanding of the individuals and the particular phenomenon being studied.

If clinical or case studies provide so much information, why are they not more frequent among researchers? As it turns out, the major benefit of this particular approach is also a weakness. As mentioned earlier, this approach is often used when studying individuals who are interesting to researchers because they have a rare characteristic. Therefore, the individuals who serve as the focus of case studies are not like most other people. If scientists ultimately want to explain all behavior, focusing attention on such a special group of people can make it difficult to generalize any observations to the larger population as a whole. Generalizing refers to the ability to apply the findings of a particular research project to larger segments of society. Again, case studies provide enormous amounts of information, but since the cases are so specific, the potential to apply what’s learned to the average person may be very limited.

Naturalistic Observation

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances are that almost everyone in the classroom will raise their hand, but do you think hand washing after every trip to the restroom is really that universal?

This is very similar to the phenomenon mentioned earlier in this chapter: many individuals do not feel comfortable answering a question honestly. But if we are committed to finding out the facts about hand washing, we have other options available to us.

Suppose we send a classmate into the restroom to actually watch whether everyone washes their hands after using the restroom. Will our observer blend into the restroom environment by wearing a white lab coat, sitting with a clipboard, and staring at the sinks? We want our researcher to be inconspicuous—perhaps standing at one of the sinks pretending to put in contact lenses while secretly recording the relevant information. This type of observational study is called naturalistic observation : observing behavior in its natural setting. To better understand peer exclusion, Suzanne Fanger collaborated with colleagues at the University of Texas to observe the behavior of preschool children on a playground. How did the observers remain inconspicuous over the duration of the study? They equipped a few of the children with wireless microphones (which the children quickly forgot about) and observed while taking notes from a distance. Also, the children in that particular preschool (a “laboratory preschool”) were accustomed to having observers on the playground (Fanger, Frankel, & Hazen, 2012).

It is critical that the observer be as unobtrusive and as inconspicuous as possible: when people know they are being watched, they are less likely to behave naturally. If you have any doubt about this, ask yourself how your driving behavior might differ in two situations: In the first situation, you are driving down a deserted highway during the middle of the day; in the second situation, you are being followed by a police car down the same deserted highway ( Figure 2.7 ).

It should be pointed out that naturalistic observation is not limited to research involving humans. Indeed, some of the best-known examples of naturalistic observation involve researchers going into the field to observe various kinds of animals in their own environments. As with human studies, the researchers maintain their distance and avoid interfering with the animal subjects so as not to influence their natural behaviors. Scientists have used this technique to study social hierarchies and interactions among animals ranging from ground squirrels to gorillas. The information provided by these studies is invaluable in understanding how those animals organize socially and communicate with one another. The anthropologist Jane Goodall , for example, spent nearly five decades observing the behavior of chimpanzees in Africa ( Figure 2.8 ). As an illustration of the types of concerns that a researcher might encounter in naturalistic observation, some scientists criticized Goodall for giving the chimps names instead of referring to them by numbers—using names was thought to undermine the emotional detachment required for the objectivity of the study (McKie, 2010).

The greatest benefit of naturalistic observation is the validity , or accuracy, of information collected unobtrusively in a natural setting. Having individuals behave as they normally would in a given situation means that we have a higher degree of ecological validity, or realism, than we might achieve with other research approaches. Therefore, our ability to generalize the findings of the research to real-world situations is enhanced. If done correctly, we need not worry about people or animals modifying their behavior simply because they are being observed. Sometimes, people may assume that reality programs give us a glimpse into authentic human behavior. However, the principle of inconspicuous observation is violated as reality stars are followed by camera crews and are interviewed on camera for personal confessionals. Given that environment, we must doubt how natural and realistic their behaviors are.

The major downside of naturalistic observation is that they are often difficult to set up and control. In our restroom study, what if you stood in the restroom all day prepared to record people’s hand washing behavior and no one came in? Or, what if you have been closely observing a troop of gorillas for weeks only to find that they migrated to a new place while you were sleeping in your tent? The benefit of realistic data comes at a cost. As a researcher you have no control of when (or if) you have behavior to observe. In addition, this type of observational research often requires significant investments of time, money, and a good dose of luck.

Sometimes studies involve structured observation. In these cases, people are observed while engaging in set, specific tasks. An excellent example of structured observation comes from Strange Situation by Mary Ainsworth (you will read more about this in the chapter on lifespan development). The Strange Situation is a procedure used to evaluate attachment styles that exist between an infant and caregiver. In this scenario, caregivers bring their infants into a room filled with toys. The Strange Situation involves a number of phases, including a stranger coming into the room, the caregiver leaving the room, and the caregiver’s return to the room. The infant’s behavior is closely monitored at each phase, but it is the behavior of the infant upon being reunited with the caregiver that is most telling in terms of characterizing the infant’s attachment style with the caregiver.

Another potential problem in observational research is observer bias . Generally, people who act as observers are closely involved in the research project and may unconsciously skew their observations to fit their research goals or expectations. To protect against this type of bias, researchers should have clear criteria established for the types of behaviors recorded and how those behaviors should be classified. In addition, researchers often compare observations of the same event by multiple observers, in order to test inter-rater reliability : a measure of reliability that assesses the consistency of observations by different observers.

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally ( Figure 2.9 ). Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Surveys allow researchers to gather data from larger samples than may be afforded by other research methods . A sample is a subset of individuals selected from a population , which is the overall group of individuals that the researchers are interested in. Researchers study the sample and seek to generalize their findings to the population. Generally, researchers will begin this process by calculating various measures of central tendency from the data they have collected. These measures provide an overall summary of what a typical response looks like. There are three measures of central tendency: mode, median, and mean. The mode is the most frequently occurring response, the median lies at the middle of a given data set, and the mean is the arithmetic average of all data points. Means tend to be most useful in conducting additional analyses like those described below; however, means are very sensitive to the effects of outliers, and so one must be aware of those effects when making assessments of what measures of central tendency tell us about a data set in question.

There is both strength and weakness of the survey in comparison to case studies. By using surveys, we can collect information from a larger sample of people. A larger sample is better able to reflect the actual diversity of the population, thus allowing better generalizability. Therefore, if our sample is sufficiently large and diverse, we can assume that the data we collect from the survey can be generalized to the larger population with more certainty than the information collected through a case study. However, given the greater number of people involved, we are not able to collect the same depth of information on each person that would be collected in a case study.

Another potential weakness of surveys is something we touched on earlier in this chapter: People don't always give accurate responses. They may lie, misremember, or answer questions in a way that they think makes them look good. For example, people may report drinking less alcohol than is actually the case.

Any number of research questions can be answered through the use of surveys. One real-world example is the research conducted by Jenkins, Ruppel, Kizer, Yehl, and Griffin (2012) about the backlash against the US Arab-American community following the terrorist attacks of September 11, 2001. Jenkins and colleagues wanted to determine to what extent these negative attitudes toward Arab-Americans still existed nearly a decade after the attacks occurred. In one study, 140 research participants filled out a survey with 10 questions, including questions asking directly about the participant’s overt prejudicial attitudes toward people of various ethnicities. The survey also asked indirect questions about how likely the participant would be to interact with a person of a given ethnicity in a variety of settings (such as, “How likely do you think it is that you would introduce yourself to a person of Arab-American descent?”). The results of the research suggested that participants were unwilling to report prejudicial attitudes toward any ethnic group. However, there were significant differences between their pattern of responses to questions about social interaction with Arab-Americans compared to other ethnic groups: they indicated less willingness for social interaction with Arab-Americans compared to the other ethnic groups. This suggested that the participants harbored subtle forms of prejudice against Arab-Americans, despite their assertions that this was not the case (Jenkins et al., 2012).

Archival Research

Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research . Archival research relies on looking at past records or data sets to look for interesting patterns or relationships.

For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and calculate how long it took them to complete their degrees, as well as course loads, grades, and extracurricular involvement. Archival research could provide important information about who is most likely to complete their education, and it could help identify important risk factors for struggling students ( Figure 2.10 ).

In comparing archival research to other research methods, there are several important distinctions. For one, the researcher employing archival research never directly interacts with research participants. Therefore, the investment of time and money to collect data is considerably less with archival research. Additionally, researchers have no control over what information was originally collected. Therefore, research questions have to be tailored so they can be answered within the structure of the existing data sets. There is also no guarantee of consistency between the records from one source to another, which might make comparing and contrasting different data sets problematic.

Longitudinal and Cross-Sectional Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again at age 40.

Another approach is cross-sectional research. In cross-sectional research , a researcher compares multiple segments of the population at the same time. Using the dietary habits example above, the researcher might directly compare different groups of people by age. Instead of studying a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old individuals. While cross-sectional research requires a shorter-term investment, it is also limited by differences that exist between the different generations (or cohorts) that have nothing to do with age per se, but rather reflect the social and cultural experiences of different generations of individuals that make them different from one another.

To illustrate this concept, consider the following survey findings. In recent years there has been significant growth in the popular support of same-sex marriage. Many studies on this topic break down survey participants into different age groups. In general, younger people are more supportive of same-sex marriage than are those who are older (Jones, 2013). Does this mean that as we age we become less open to the idea of same-sex marriage, or does this mean that older individuals have different perspectives because of the social climates in which they grew up? Longitudinal research is a powerful approach because the same individuals are involved in the research project over time, which means that the researchers need to be less concerned with differences among cohorts affecting the results of their study.

Often longitudinal studies are employed when researching various diseases in an effort to understand particular risk factors. Such studies often involve tens of thousands of individuals who are followed for several decades. Given the enormous number of people involved in these studies, researchers can feel confident that their findings can be generalized to the larger population. The Cancer Prevention Study-3 (CPS-3) is one of a series of longitudinal studies sponsored by the American Cancer Society aimed at determining predictive risk factors associated with cancer. When participants enter the study, they complete a survey about their lives and family histories, providing information on factors that might cause or prevent the development of cancer. Then every few years the participants receive additional surveys to complete. In the end, hundreds of thousands of participants will be tracked over 20 years to determine which of them develop cancer and which do not.

Clearly, this type of research is important and potentially very informative. For instance, earlier longitudinal studies sponsored by the American Cancer Society provided some of the first scientific demonstrations of the now well-established links between increased rates of cancer and smoking (American Cancer Society, n.d.) ( Figure 2.11 ).

As with any research strategy, longitudinal research is not without limitations. For one, these studies require an incredible time investment by the researcher and research participants. Given that some longitudinal studies take years, if not decades, to complete, the results will not be known for a considerable period of time. In addition to the time demands, these studies also require a substantial financial investment. Many researchers are unable to commit the resources necessary to see a longitudinal project through to the end.

Research participants must also be willing to continue their participation for an extended period of time, and this can be problematic. People move, get married and take new names, get ill, and eventually die. Even without significant life changes, some people may simply choose to discontinue their participation in the project. As a result, the attrition rates, or reduction in the number of research participants due to dropouts, in longitudinal studies are quite high and increase over the course of a project. For this reason, researchers using this approach typically recruit many participants fully expecting that a substantial number will drop out before the end. As the study progresses, they continually check whether the sample still represents the larger population, and make adjustments as necessary.

Emory primatologist Frans de Waal remembered for bringing apes ‘a little closer to humans’

Emory University | March 16, 2024

40 years of publishing : From "Chimpanzee Politics" in 1982 to "Different" in 2022.

Emory University primatologist Frans de Waal — who pioneered studies of animal cognition while also writing best-selling books that helped popularize the field around the globe — passed away March 14, 2024, from stomach cancer.

De Waal, Charles Howard Candler Professor Emeritus of Psychology and former director of the Living Links Center for the Advanced Study of Ape and Human Evolution at the Emory National Primate Research Center, was 75.

From his groundbreaking 1982 book “Chimpanzee Politics: Power and Sex Among Apes” to 2019’s “Mama’s Last Hug: Animal Emotions and What They Tell Us About Ourselves,” de Waal shattered long-held ideas about what it means to be an animal and a human.

“One thing that I’ve seen often in my career is claims of human uniqueness that fall away and are never heard from again,” de Waal said in 2014. “We always end up overestimating the complexity of what we do. That’s how you can sum up my career: I’ve brought apes a little closer to humans but I’ve also brought humans down a bit.”

“It’s difficult to sum up the enormity of Frans de Waal’s impact, both globally and here at Emory,” says Lynne Nygaard, chair of Emory’s Department of Psychology. “He was an extraordinarily deep thinker who could also think broadly, making insights that cut across disciplines. He was always ready to participate in an intellectual discussion.”

In addition to being a world-renowned scholar, beloved teacher and supportive colleague, “Frans was funny,” Nygaard says. “If a discussion became fraught, he could make just the right irreverent remark to get everyone to laugh and break the tension.”

“We may accept that we are descended from apes, but it takes the likes of Frans de Waal to remind us that we haven't traveled that far.” —TIME Magazine, Top 100 People who Shape Our World

Breaking taboos

George Romanes, a protégé of Charles Darwin, tried to connect ideas of animal consciousness and human consciousness in the late 1800s, but his theories were dismissed as anecdotal and anthropomorphic.

For nearly 100 years, the subject of the social mind of animals remained largely taboo in the scientific community. Finally, in 1976, neuroscientist Donald Griffin published his first edition of “The Question of Animal Awareness: Evolutionary Continuity of Mental Experience.” That book compiled observations suggesting animals might have thoughts worthy of exploring and that it was possible to do so in a scientifically objective way.

“Donald Griffin opened the door just a little bit and then Frans pushed it wide open. The rest is history,” says Harold Gouzoules, an Emory professor of psychology who studies primate social behavior and vocal communication.

Frans de Waal as a young scholar

De Waal wrote hundreds of peer-reviewed scientific articles comparing primate and human behavior. He demonstrated the roots of human nature in our closest living relatives through his studies of conflict resolution, reconciliation, cooperation, empathy, fairness, morality, social learning and culture in chimpanzees, bonobos and capuchin monkeys.

A prolific writer and editor, his impact reached far beyond academia through his articles for major magazines and newspapers and his 16 popular books that have been translated into 20 languages. He was a gifted speaker who wove deadpan humor into his many public talks — usually filled to capacity — about his research. His TED Talks have been viewed millions of times.

Animal emotions: In this Emory video, watch Frans de Waal discuss his 2019 book, "Mama's Last Hug."

Training the next generation

Through teaching and research projects, de Waal also helped train and influence many leaders in the field of animal cognition.

“Frans was a fantastic mentor, he really believed in his students,” says Sarah Brosnan, who received a PhD in 2004 in Emory’s Population Biology, Ecology and Evolution Program. Brosnan is now Distinguished University Professor of psychology at Georgia State University where she investigates the evolution of cooperation, decision-making and economic behavior among primates.

“Frans told us the best way to come up with research questions was to watch your animals and they will tell you what’s important,” recalls Brosnan.

She took his advice to heart.

One day, while Brosnan was feeding capuchin monkeys at the primate center, she tried to distract the dominant male, Ozzie, while she slipped peanuts to the others, to keep him from grabbing them all. Ozzie caught on, however, and brought Brosnan a piece of a naval orange from his enclosure, offering it in exchange for a peanut.

Oranges are generally a choice treat to monkeys, rating even higher than peanuts. “I wondered if the reason Ozzie was willing to trade a chunk of orange for a peanut was because everyone else was eating one,” she recalls.

A master of visualization

That simple question led to Brosnan and de Waal developing the famous cucumber-grape study on fairness.

Two capuchins were situated in enclosures next to one another. A researcher would ask them to do a task and if they succeeded give them a treat. The catch was one monkey was always rewarded with a piece of cucumber while the other monkey sometimes got a piece of cucumber and sometimes got a grape — a preferred treat among capuchin monkeys.

A video de Waal filmed of one of the experiments created a media sensation.

Unequal pay for equal work:  When the first monkey gives the researcher a rock, she is rewarded with a cucumber slice. But watch what happens when the first monkey sees the second monkey hand the researcher a rock — and get a much tastier grape instead.

A monkey that received only cucumber appears perfectly happy until she sees her companion receive a grape. Then her behavior changes. She accepts the next piece of cucumber only to throw it back at the researcher, pounding the surface in front of the enclosure and shaking its Plexiglas walls.

“That video struck home with a lot of people,” Brosnan says. “Who hasn’t felt like that monkey that’s only getting cucumbers? Our research showed something about the evolution of the sense of human fairness.”

De Waal, a skilled visual artist and photographer, routinely videotaped experiments — long before that became common practice in labs.

“Both Frans and I used the cucumber-grape experiment video in our TED Talks,” Brosnan notes. “Frans taught his students how to write well and how to give a good presentation. You weren’t allowed to just read some text. Your slides always had to have images and videos.”

Animal reconciliation

Franciscus Bernardus Maria “Frans” de Waal was born in 1948 in s’Hertogenbosch, the Netherlands, where he trained as a zoologist and ethologist at three universities — Nijmegen, Groningen and Utrecht. In 1977 he received a PhD in biology from the University of Utrecht where Jan van Hooff, a Dutch biologist renowned for his research involving primates, was his mentor.

Frans de Waal as a young boy

For his dissertation, de Waal began working with the colony of chimpanzees at the Arnhem Zoo in the Netherlands. That work led to his first major discovery: chimpanzees make up after fights.

“I discovered that by just seeing how the opponents would come together after fights and kiss and embrace,” de Waal later said. “I never had trouble getting primatologists interested or convincing them, but other scientists were often skeptical. This meant conducting experiments and collecting data to convince them.”

Instead of describing the behavior he observed using a clinical term, such as “post-fight, affiliative contact,” de Waal called it reconciliation — a word, up until then, reserved for humans. This research became the basis of his book “Chimpanzee Politics,” which compared the schmoozing and scheming of chimpanzees involved in power struggles with that of human politicians.

“There really was no history of someone studying something as complex as reconciliation in animals,” says Kim Wallen, who recently retired as an Emory professor of psychology. “Frans faced a lot of challenges because he looked at questions that were outside the mainstream of animal behavior research. He persisted and carved out an area of his own.”

In 1981 de Waal moved to the United States to join the Wisconsin National Primate Research Center.

Wallen, who studied sex-related behaviors in humans and non-humans, recruited de Waal to join Emory in 1991. “His reputation preceded him,” Wallen recalls. “It was a big coup for Emory.”

Understanding our inner ape

At the field station of the Emory National Primate Research Center, de Waal kept a small office atop a tower. A windshield-like opening in the office overlooks a habitat where multi-generational groups of chimpanzees live outdoors.

De Waal supervised the construction of a building adjacent to the habitat for cognition research with the chimpanzees. A door would slide up allowing the chimpanzees to voluntarily come inside to try to solve a puzzle or perform a task.

A large part of de Waal’s research also encompassed bonobos, what he called “the forgotten ape,” including studies of bonobos in the San Diego Zoo and in the Democratic Republic of Congo. Both the chimpanzee and the bonobo are our genetic twins, but for 1.5% difference in DNA. And while chimpanzees rely on aggression to solve problems, the peaceable, sex-loving, female-dominated bonobos are so chill de Waal described them as “the hippies of the primate world.”

In his 2005 book, “Our Inner Ape,” a New York Times Notable Book of the Year, he used these contrasting ape societies as the context to examine some of the most fundamental, complex and intense manifestations of human nature.

“We have an enormous spectrum of behavior, so don’t believe claims that we are inherently nasty, aggressive, selfish and uncooperative,” de Waal said in a 2006 interview. “My argument is that we have the potential to be everything we want to be. Our job is to bring out what we want.”

Making the most of every minute

In addition to his extreme productivity as a scientist, teacher and communicator, de Waal was a social animal, especially when it came to his students.

“I think Frans came across sometimes as reserved but he wasn’t like that once you got to know him,” Brosnan says. “He was so much fun. He would hold what he called ‘simian soirees’ at his house where graduate students would gather to talk. He was a fantastic piano player and he would play for us.”

De Waal retired from Emory in 2019 but remained active. He was in demand internationally and traveled widely, attending conferences and giving public talks. “The number of talks he would give in a year was always off-the-charts impressive,” Gouzoules said. “It was almost like a rock star touring around.”

De Waal also continued writing, publishing “Different: Gender Through the Eyes of a Primatologist” in 2022. In 2023, he made an appearance in New York for a public discussion with film icon Isabella Rossellini about the book, and what we may learn about sex and gender from primate studies.

De Waal made his home in Stone Mountain, Georgia, where he lived with his wife of more than 40 years, Catherine Marin. The couple also maintained an apartment in the Netherlands where he had an affiliation with the University of Utrecht.

De Waal was made a Knight of the Order of the Netherlands Lion In 2010 and elected to the American Academy of Arts and Sciences in 2008 and the National Academy of Sciences in 2004. Among his many awards are the E.O. Wilson Literary Science Writing Award (2020), the Galileo Prize (2014), the Ig Nobel Prize (2012), Discover magazine’s “47 All-time Great Minds of Science” (2011), Time magazine’s 100 world’s most influential people (2007), the American Psychological Foundation Arthur W. Staats Award (2005) and the Los Angeles Times Book Award for “Peacemaking Among Primates” (1989).
