Principles of Social Psychology

v2.0 Charles Stangor

Preface

When I first started teaching social psychology, I had trouble figuring out how the various topics in this expansive field fit together. I felt like I was presenting a laundry list of ideas, research studies, and phenomena, rather than an integrated set of principles and knowledge. Of course, what was difficult for me was harder still for my students. How could they be expected to understand and remember all of the many topics that we social psychologists study? And how could they tell what was most important? Something was needed to structure and integrate their learning.

It took me some time, but eventually I realized that the missing piece in my lectures was a consistent focus on the basic principles of social psychology. Once I started thinking and talking about principles, then it all fell into place. I knew that when I got to my lecture on altruism, most of my students already knew what I was about to tell them. They understood that, although there were always some tweaks to keep things interesting, altruism was going to be understood using the same ideas that conformity and person perception had been in earlier lectures—in terms of the underlying fundamentals—they were truly thinking like social psychologists!

I wrote this book from the student perspective, by asking “what is important to students?” “How do students learn?” and “How will students remember the important concepts of social psychology?” This allowed me to help students organize their thinking about social psychology at a conceptual level. Five or ten years from now, I do not expect my students to remember the details of a study published in 2016, or even to remember most of the definitions in this book. I do hope, however, that they will remember some basic ideas, for it is these principles that will allow them to critically analyze new situations and really put their knowledge to use.

My text is therefore based on a critical thinking approach—its aim is to get students thinking actively and conceptually—with more of a focus on the forest than on the trees. Although there are right and wrong answers, knowing the answers is not the most important outcome. What is perhaps even more important is how we get to those answers—the thinking process itself. My efforts are successful when my students have that “aha” moment, in which they find new ideas fitting snugly into the basic concepts of social psychology.

To help students better grasp the big picture of social psychology and to provide you with a theme that you can use to organize your lectures, my text has a consistent pedagogy across the chapters. I organize my presentation around three underlying principles that are essential to social psychology:

  1. Person versus situation

  2. Affect, Behavior and Cognition

  3. Self-concern and other-concern

The third principle (self-concern versus other-concern) is based on a distinction that I see as fundamental to social psychology. This distinction concerns orientations that benefit the self and the ingroup versus orientations that benefit other people more broadly. The distinction has long been implicit in social psychological theorizing, but has recently become more explicit.  Examples are abounding in the literatures on altruism, aggression, stereotypes and prejudice, morality, political psychology, close relationships, and interpersonal trust and cooperation. I use the two human fundamental motivations of self-concern and other-concern to frame these discussions and you can incorporate these dimensions into your teaching as you see fit.

My years of teaching have convinced me that these dimensions are fundamental, that they are extremely heuristic, and that they are what I hope my students will learn and remember. I think that you may find that this organization represents a more explicit representation of what you’re already doing in your lectures. Although my pedagogy is consistent, it is not constraining. You will use these dimensions more in some lectures than in others, and you will find them more useful for some topics than others. But they will always work for you when you are ready for them. Use them to reinforce your presentation as you see fit.

Perhaps most important, a focus on these dimensions helps us bridge the gap between the textbook, the real-life experiences of our students, and our class presentations. We can’t cover every phenomenon in our lectures—we naturally let the textbook fill in the details. The goal of my book is to allow you to rest assured that the text has provided your students with the foundations—the fundamental language of social psychology—from which you can build as you see fit. And when you turn to ask students to apply their learning to real life, you can know that they will be doing this as social psychologists do—using a basic underlying framework.

Organization

The text moves systematically from lower to higher levels of analysis—a method that I have found makes sense to students. On the other hand, the chapter order should not constrain you—choose a different order if you wish. Chapter 1 “Introducing Social Psychology” presents an introduction to social psychology and the research methods in social psychology, Chapter 2 “Social Learning and Social Cognition” presents the fundamental principles of social cognition, and Chapter 3 “Social Affect” focuses on social affect. The remainder of the text is organized around three levels of analysis, moving systematically from the individual level (Chapter 4 “The Self” through Chapter 6 “Perceiving Others”), to the level of social interaction (Chapter 7 “Influencing and Conforming” through Chapter 10 “Aggression”), to the group and cultural level (Chapter 11 “Group Performance and Decision Making” through Chapter 13 “Competition and Cooperation in Our Social Worlds”).

Rather than relying on “modules” or “appendices” of applied materials, my text integrates applied concepts into the text itself. This approach is consistent with my underlying belief that if students learn to think like social psychologists they will easily and naturally apply that knowledge to any and all applications. The following applications are woven throughout the text:

  1. Business and consumer behavior (see, for instance, Chapter 5 “Attitudes, Behavior, and Persuasion” on marketing and persuasion and Chapter 11 “Group Performance and Decision Making” on group decision making)

  2. Politics and Government (see for instance, Chapter 12 “Stereotypes, Prejudice, and Discrimination” and Chapter 10 “Aggression” on Terrorism)

  3. Health and Behavior (see, for instance, Chapter 3 “Social Affect” on stress and Chapter 6 “Perceiving Others” on attributional styles)

  4. Law (see, for instance, Chapter 2 “Social Learning and Social Cognition” on eyewitness testimony 

Pedagogy

Principles of Social Psychology contains a number of pedagogical features designed to help students develop an active, integrative understanding of the many topics of social psychology and to think like social psychologists.

Research Foci

Research is of course the heart of social psychology, and the research foci provide detailed information about a study or research program. I’ve chosen a mix of classic and contemporary research, with a focus on both what’s interesting and what’s pedagogical. Rather than boxing these findings, they are part of the running text—simply highlighted with a heading and light shading.

Social Psychology in the Public Interest

Social psychological findings interest students in large part because they relate so directly to everyday experience. The Social Psychology in the Public Interest Feature reinforces these links. Topics include Does High Self-Esteem Cause Happiness or Other Positive Outcomes? (Chapter 3 “Social Affect”), Detecting Deception (Chapter 6 “Perceiving Others”), Terrorism as Instrumental Aggression (Chapter 10 “Aggression”), and Stereotype Threat in Schools (Chapter 12 “Stereotypes, Prejudice, and Discrimination”). The goal here is to include these applied topics within the relevant conceptual discussions to provide students with a richer understanding within the context of the presentation.

Thinking Like a Social Psychologist

Each chapter ends with a section that summarizes how the material presented in the chapter can help the student think about contemporary issues using social psychological principles. This section is designed to work with the chapter summary to allow a better integration of fundamental concepts.

Replication in Social Psychology

The current “replicability crisis” in psychology, and particularly in social psychology, has created some doubt about the findings reported in the literature and in social psychology textbooks. Along with researchers, reviewers, and journal editors, textbook authors are required to use their best judgment about which findings are “real” and which are not. 

Although some might believe that past “questionable research practices” have left the entire field open to interpretation, this is most certainly not the case. Despite the immense difficulty of drawing conclusions about social behavior, social psychology has created a wealth of valid knowledge. Not every experiment will replicate, but many replications, when conducted properly, will.  When we look at the forest, rather than the trees, the picture is a lot clearer. 

In this second edition, I have taken this approach: If there is clear reason to doubt that a relationship is real, then I have removed it from discussion. If there have been some failures to replicate then I will note this in the text. Otherwise, we must all continually remind students that all research is provisional—no one experiment “proves” a theory or concept.

Changes in the Second Edition

The second edition of Principles of Social Psychology keeps the overarching structure of the first, but provides updates based on new theoretical and research advances over the past five years. These changes include:

  1. An updated discussion of our human evolutionary past (Chapter 1)

  2. An expanded discussion of evolutionary psychology (Chapter 2)

  3. An expanded discussion of explicit racism and intergroup violence (Chapter 12)

  4. An expanded discussion of contemporary theories of morality (Chapter 13)

Throughout the text:

  1. Many figures have been updated, and now include in-text guidelines for interpreting figures that depict statistical interactions.

  2. There are many new chapter openers, including the benefits of mindfulness (Chapter 3), the Trump presidential campaign (Chapter 5), the 2017 Quebec City mosque attack (Chapter 9), racism and the Black Lives Movement (Chapter 12), and global warming as a social dilemma (Chapter 13).

  3. A number of citations related to the effects of social media use on personality and behavior have been added.

I hope you and your students enjoy my book. My goal is to treat social psychology as a serious scientific field.  The text is not an elementary or high school text—there are no cartoons, and the text is straightforward but complete.
