Exploring PSYCHOLOGY, tenth edition

Preface

xvi

In the 27 years since Worth Publishers invited me (David Myers) to write this book, so much has changed in the world, in psychology, and within these course resources, across ten editions. With this edition, I continue as lead author while beginning a gradual, decade-long process of welcoming a successor author, the award-winning teacher-scholar-writer Nathan DeWall.

Yet across nearly three decades of Exploring Psychology there has also been a stability of purpose: to merge rigorous science with a broad human perspective that engages both mind and heart. We aim to offer a state-of-the-art introduction to psychological science that speaks to students’ needs and interests. We aspire to help students understand and appreciate the wonders of their everyday lives. And we seek to convey the inquisitive spirit with which psychologists do psychology.

We are enthusiastic about psychology and its applicability to our lives. Psychological science has the potential to expand our minds and enlarge our hearts. By studying and applying its tools, ideas, and insights, we can supplement our intuition with critical thinking, restrain our judgmentalism with compassion, and replace our illusions with understanding. By the time students complete this guided tour of psychology, they will also, we hope, have a deeper understanding of our moods and memories, about the reach of our unconscious, about how we flourish and struggle, about how we perceive our physical and social worlds, and about how our biology and culture in turn shape us. (See TABLE 1 and TABLE 2.)

xvii

Believing with Thoreau that “anything living is easily and naturally expressed in popular language,” we seek to communicate psychology’s scholarship with crisp narrative and vivid storytelling. We hope to tell psychology’s story in a way that is warmly personal as well as rigorously scientific. We love to reflect on connections between psychology and other realms, such as literature, philosophy, history, sports, religion, politics, and popular culture. And we love to provoke thought, to play with words, and to laugh. For his pioneering 1890 Principles of Psychology, William James sought “humor and pathos.” And so do we.

xviii

We are grateful for the privilege of assisting with the teaching of this mind-expanding discipline to so many students, in so many countries, through so many different languages. To be entrusted with discerning and communicating psychology’s insights is both an exciting honor and a great responsibility.

Creating this book is a team sport. Like so many human achievements, it reflects a collective intelligence. Woodrow Wilson spoke for us: “I not only use all the brains I have, but all I can borrow.” The thousands of instructors and millions of students across the globe who have taught or studied (or both!) with our books have contributed immensely to their development. Much of this contribution has occurred spontaneously, through correspondence and conversations. For this edition, we also formally involved dozens of researchers, teaching psychologists, and students in our efforts to gather accurate and up-to-date information about psychology and instructor and student needs. And we look forward to continuing feedback as we strive, over future editions, to create an ever better set of resources for this course.

New Co-Author

For this edition I [DM] welcome my new co-author, University of Kentucky professor Nathan DeWall. (For more information and videos that introduce Nathan and our collaboration, see www.MacmillanHigherEd.com/DeWallVideos.) Nathan is not only one of psychology’s “rising stars” (as the Association for Psychological Science rightly said in 2011), he also is an award-winning teacher and someone who shares my passion for writing—and for communicating psychological science through writing. Although I continue as lead author, Nathan’s fresh insights and contributions are already enriching this book, especially for this tenth edition, through his leading the revision of Chapters 2, 4, 11, and 13. But my fingerprints are also on those chapter revisions, even as his are on the other chapters. With support from our wonderful editors, this is a team project. In addition to our work together on the textbook, Nathan and I enjoy contributing to the monthly Teaching Current Directions in Psychological Science column in the APS Observer (tinyurl.com/MyersDeWall). We also blog at www.TalkPsych.com, where we share exciting new findings, everyday applications, and observations on all things psychology.

What Else Is New in the Tenth Edition?

This tenth edition is the most carefully reworked and extensively updated of all the revisions to date. This new edition features improvements to the organization and presentation, especially to our system of supporting student learning and remembering. And we offer the exciting new Immersive Learning: How Would You Know? feature in LaunchPad, engaging students in the scientific process.

“Immersive Learning: How Would You Know?” Research Activities

We [ND and DM] created these online activities to engage students in the scientific process, showing them how psychological research begins with a question, and how key decision points can alter the meaning and value of a psychological study. In a fun, interactive environment, students learn about important aspects of research design and interpretation, and develop scientific literacy and critical thinking skills in the process. I [ND] have enjoyed taking the lead on this project and sharing my research experience and enthusiasm with students. Topics include: “How Would You Know If a Cup of Coffee Can Warm Up Relationships?,” “How Would You Know If People Can Learn to Reduce Anxiety?,” and “How Would You Know If Schizophrenia Is Inherited?”

New Visual Scaffolding Chapter Openers

We were aware that students often skip over a text’s typical two-page chapter opener—under the assumption it serves little purpose in learning the material to come. So, for this new edition, we worked with a talented artist to make more pedagogically effective use of this space. This new feature provides an enticing and helpful way for students to SURVEY the content in each chapter, before they QUESTION, READ, RETRIEVE, and REVIEW it (SQ3R). We’ve provided visual scaffolding at the beginning of each chapter, offering students a basic cognitive structure for the content to come. Flip to the beginning of any chapter to see a sample.

Hundreds of New Research Citations

Our ongoing scrutiny of dozens of scientific periodicals and science news sources, enhanced by commissioned reviews and countless e-mails from instructors and students, enables integrating our field’s most important, thought-provoking, and student-relevant new discoveries. Part of the pleasure that sustains this work is learning something new every day! See p. xxxvi for a list of significant Content Changes to this edition.

Reorganized Chapters

In addition to the new research activities, visual scaffolding openers, and updated coverage, we’ve introduced the following organizational changes:

Chapter 1, Thinking Critically With Psychological Science, now has a clearer organization and greater emphasis on modern approaches, including Cross-Cultural and Gender Psychology, and new coverage of Positive Psychology (see also TABLE 3). This chapter also now offers greater emphasis on designing psychological studies, and on psychology’s research ethics.
Hypnosis is now covered in the Pain discussion in Chapter 6, Sensation and Perception (moved from Chapter 3).
The Social Psychology chapter now precedes the Personality chapter.

LaunchPad for Exploring Psychology, Tenth Edition

Figure 1.1: FIGURE 1 Sample LaunchPad callout from Chapter 12

Built to solve key challenges in this course, LaunchPad gives students everything they need to prepare for class and exams, while giving instructors everything they need to quickly set up a course, shape the content to their syllabus, craft presentations and lectures, assign and assess homework, and guide the progress of individual students and the class as a whole. LaunchPad for Exploring Psychology, tenth edition, includes LearningCurve formative assessment, and NEW Immersive Learning: How Would You Know? activities, PsychSim 6 tutorials, and Assess Your Strengths projects. (For details, see p. xxviii and www.MacmillanHigherEd.com/LaunchPad/Exploring10e.)

For this new edition, you will see that we’ve offered callouts from the text pages to especially pertinent, helpful resources from LaunchPad. (See FIGURE 1 for a sample.)

What Continues?

Eight Guiding Principles

Despite all the exciting changes, this new edition retains its predecessors’ voice, as well as much of the content and organization. It also retains the goals—the guiding principles—that have animated the previous nine editions:

Facilitating the Learning Experience

To teach critical thinking By presenting research as intellectual detective work, we illustrate an inquiring, analytical mind-set. Whether students are studying development, cognition, or social behavior, they will become involved in, and see the rewards of, critical reasoning. Moreover, they will discover how an empirical approach can help them evaluate competing ideas and claims for highly publicized phenomena—ranging from ESP and alternative therapies to group differences in intelligence and repressed and recovered memories.
To integrate principles and applications Throughout—by means of anecdotes, case histories, and the posing of hypothetical situations—we relate the findings of basic research to their applications and implications. Where psychology can illuminate pressing human issues—be they racism and sexism, health and happiness, or violence and war—we have not hesitated to shine its light.
To reinforce learning at every step Everyday examples and rhetorical questions encourage students to process the material actively. Concepts presented earlier are frequently applied, and reinforced. For instance, in Chapter 1, students learn that much of our information processing occurs outside of our conscious awareness. Ensuing chapters drive home this concept. Numbered Learning Objective Questions and Retrieve It self-tests throughout each chapter, a Review and Experience the Testing Effect self-test at the end of each main text section, and a pop-up glossary help students learn and retain important concepts and terminology.

Demonstrating the Science of Psychology

To exemplify the process of inquiry We strive to show students not just the outcome of research, but how the research process works. Throughout, we try to excite the reader’s curiosity. We invite readers to imagine themselves as participants in classic experiments. Several chapters introduce research stories as mysteries that progressively unravel as one clue after another falls into place. Our new “Immersive Learning: How Would You Know?” activities in LaunchPad encourage students to think about research questions and how they may be studied effectively.
To be as up-to-date as possible Few things dampen students’ interest as quickly as the sense that they are reading stale news. While retaining psychology’s classic studies and concepts, we also present the discipline’s most important recent developments. In this edition, 701 references are dated 2013–2015. Likewise, new photos and everyday examples are drawn from today’s world.
To put facts in the service of concepts Our intention is not to fill students’ intellectual file drawers with facts, but to reveal psychology’s major concepts—to teach students how to think, and to offer psychological ideas worth thinking about. In each chapter, we place emphasis on those concepts we hope students will carry with them long after they complete the course. Always, we try to follow Albert Einstein’s purported dictum that “everything should be made as simple as possible, but not simpler.” Learning Objective Questions, Retrieve It questions, and Experience the Testing Effect questions throughout each chapter help students learn and retain the key concepts.

xxi

Promoting Big Ideas and Broadened Horizons

To enhance comprehension by providing continuity Many chapters have a significant issue or theme that links subtopics, forming a thread that ties ideas together. The Learning chapter conveys the idea that bold thinkers can serve as intellectual pioneers. The Thinking, Language, and Intelligence chapter raises the issue of human rationality and irrationality. The Psychological Disorders chapter conveys empathy for, and understanding of, troubled lives. Other threads, such as cognitive neuroscience, dual processing, and cultural and gender diversity, weave throughout the whole book, and students hear a consistent voice.
To convey respect for human unity and diversity Throughout the book, readers will see evidence of our human kinship—our shared biological heritage, our common mechanisms of seeing and learning, hungering and feeling, loving and hating. They will also better understand the dimensions of our diversity—our individual diversity in development and aptitudes, temperament and personality, and disorder and health; and our cultural diversity in attitudes and expressive styles, child raising and care for the elderly, and life priorities.

Study System Follows Best Practices From Learning and Memory Research

Exploring Psychology, tenth edition’s learning system harnesses the testing effect, which documents the benefits of actively retrieving information through selftesting (FIGURE 2). Thus, each chapter offers 15 to 20 Retrieve It questions interspersed throughout, with Experience the Testing Effect self-test questions at the end of each main section. Creating these desirable difficulties for students along the way optimizes the testing effect, as does immediate feedback.

Figure 1.2: FIGURE 2 How to learn and remember For a 5-minute animated guide to more effective studying, visit www.tinyurl.com/HowToRemember.

In addition, text sections begin with numbered questions that establish learning objectives and direct student reading. A Review section follows each main section of text, providing students an opportunity to practice rehearsing what they’ve just learned. The Review offers self-testing by repeating the Learning Objective Questions (with answers for checking against), along with a page-referenced list of key terms.

Continually Improving Cultural and Gender Diversity Coverage

Discussion of the relevance of cultural and gender diversity begins on the first page and continues throughout the text.

This edition presents an even more thoroughly cross-cultural perspective on psychology (TABLE 4)—reflected in research findings, and text and photo examples. Cross-cultural and gender psychology are now given greater visibility with enhanced coverage moved to Chapter 1. There is focused coverage of the psychology of women and men in Chapter 5, Sex, Gender, and Sexuality, with thoroughly integrated coverage throughout the text (see TABLE 5). In addition, we are working to offer a world-based psychology for our worldwide student readership. We continually search the world for research findings and text and photo examples, conscious that readers may be in Sydney, Seattle, or Singapore. Although we reside in the United States, we travel abroad regularly and maintain contact with colleagues in Canada, Britain, South Africa, China, and many other places; and subscribe to European periodicals. Thus, each new edition offers a broad, world-based perspective, and includes research from around the world. We are all citizens of a shrinking world, so American students, too, benefit from information and examples that internationalize their world-consciousness. And if psychology seeks to explain human behavior (not just American or Canadian or Australian behavior), the broader the scope of studies presented, the more accurate is our picture of this world’s people. Our aim is to expose all students to the world beyond their own culture, and we continue to welcome input and suggestions from all readers.

Strong Critical Thinking Coverage

We love to write in a way that gets students thinking and keeps them active as they read, and we aim to introduce students to critical thinking throughout the book. Revised and more plentiful Learning Objective Questions at the beginning of text sections, and even more regular Retrieve It questions encourage critical reading to glean an understanding of important concepts. This tenth edition also includes the following opportunities for students to learn or practice their critical thinking skills.

Chapter 1, Thinking Critically With Psychological Science, introduces students to psychology’s research methods, emphasizing the fallacies of our everyday intuition and common sense and, thus, the need for psychological science. Critical thinking is introduced as a key term on page 3. Appendix A, Statistical Reasoning in Everyday Life, encourages students to “focus on thinking smarter by applying simple statistical principles to everyday reasoning.”
“Thinking Critically About . . .” boxes are found throughout the book, modeling for students a critical approach to some key issues in psychology. For example, see “Thinking Critically About: Why We Fear the Wrong Things” (Chapter 9), or “Thinking Critically About: The Stigma of Introversion” (Chapter 13).
Detective-style stories throughout the narrative get students thinking critically about psychology’s key research questions. For example, in Chapter 14, we present the causes of schizophrenia piece by piece, showing students how researchers put the puzzle together.
“Apply this” and “Think about it” style discussions keep students active in their study. In Chapter 12, for example, students take the perspective of participants in a Solomon Asch conformity experiment, and later in one of Stanley Milgram’s obedience experiments. We’ve also asked students to join the fun by taking part in activities they can try along the way. For example, in Chapter 6, they try out a quick sensory adaptation activity. In Chapter 10, they try matching expressions to faces and test the effects of different facial expressions on themselves.
Critical examinations of pop psychology spark interest and provide important lessons in thinking critically about everyday topics. For example, Chapter 6 offers an examination of ESP claims, and Chapter 8 examines claims of the repression of painful memories.

See TABLE 6 for a complete list of this text’s coverage of critical thinking topics and Thinking Critically About boxes.

APA Assessment Tools

In 2011, the American Psychological Association (APA) approved the Principles for Quality Undergraduate Education in Psychology. These broad-based principles and their associated recommendations were designed to “produce psychologically literate citizens who apply the principles of psychological science at work and at home.” (See www.APA.org/Education/Undergrad/Principles.aspx.)

APA’s more specific 2013 Learning Goals and Outcomes, from their Guidelines for the Undergraduate Psychology Major, Version 2.0, were designed to gauge progress in students graduating with psychology majors. (See www.APA.org/Ed/Precollege/About/PsyMajor-Guidelines.pdf.) Many psychology departments use these goals and outcomes to help establish their own benchmarks for departmental assessment purposes.

Some instructors are eager to know whether a given text for the introductory course helps students get a good start at achieving these APA benchmarks. TABLE 7 (below) outlines the way Exploring Psychology, tenth edition, could help you to address the 2013 APA Learning Goals and Outcomes in your department.

In addition, an APA working group in 2013 drafted guidelines for Strengthening the Common Core of the Introductory Psychology Course (http://tinyurl.com/14dsdx5). Their goals are to “strike a nuanced balance providing flexibility yet guidance.” The group noted that “a mature science should be able to agree upon and communicate its unifying core while embracing diversity.”

MCAT Now Includes Psychology

Since 2015, the Medical College Admission Test (MCAT) has devoted 25 percent of its questions to the “Psychological, Social, and Biological Foundations of Behavior,” with most of those questions coming from the psychological science taught in introductory psychology courses. From 1977 to 2014, the MCAT focused on biology, chemistry, and physics. Hereafter, reported the Preview Guide for MCAT 2015, the exam will also recognize “the importance of socio-cultural and behavioral determinants of health and health outcomes.” The exam’s new psychology section includes the breadth of topics in this text. For example, see TABLE 8a and TABLE 8b, which outline the precise correlation between the topics in this text’s Sensation and Perception chapter and the corresponding portion of the MCAT exam. To improve their MCAT preparation, I [ND] have taught premedical students an intensive course covering the topics that appear in this text. For a complete pairing of the new MCAT psychology topics with this book’s contents, see www.MacmillanHigherEd.com/Catalog/Product/ExploringPsychology-TenthEdition-Myers.

Study Guide
Pursuing Human Strengths: A Positive Psychology Guide, Second Edition
Critical Thinking Companion, Third Edition
Psychology and the Real World: Essays Illustrating Fundamental Contributions to Society, Second Edition. This project of the FABBS Foundation brought together a virtual “Who’s Who” of contemporary psychological scientists to describe—in clear, captivating ways—the research they have passionately pursued and what it means to the “real world.” Each contribution is an original essay written for this project.
The Horse That Won’t Go Away Tom Heinzen, Scott Lilienfeld, and Susan Nolan explore the confounding story of Clever Hans and how we continue to be deceived by beliefs with no supporting logic or evidence. This supplemental book shows just how important it is to rely on the scientific method as we navigate our way through everyday life.

In Appreciation

If it is true that “whoever walks with the wise becomes wise” then we are wiser for all the wisdom and advice received from colleagues. Aided by thousands of consultants and reviewers over the last three decades, this has become a better, more effective, more accurate book than two authors alone (these two authors, at least) could write. All of us together are smarter than any one of us.

Our indebtedness continues to each of the teacher-scholars whose influence was acknowledged in the nine previous editions, to the innumerable researchers who have been so willing to share their time and talent to help us accurately report their research, and to the hundreds of instructors who have taken the time to offer feedback over the phone, in a survey or review, or at one of our face-to-face focus groups.

Our gratitude extends to the colleagues who contributed criticism, corrections, and creative ideas related to the content, pedagogy, and format of this new edition and its teaching package. For their expertise and encouragement, and the gifts of their time to the teaching of psychology, we thank the reviewers and consultants listed here.

At Worth Publishers a host of people played key roles in creating this tenth edition.

Although the information gathering is never ending, the formal planning began as the author-publisher team gathered for a two-day retreat. This happy and creative gathering included John Brink, Thomas Ludwig, Richard Straub, Nathan, and Dave from the author team, along with assistants Kathryn Brownson and Sara Neevel. We were joined by Worth Publishers executives Tom Scotty, Joan Feinberg, Craig Bleyer, Doug Bolton, Catherine Woods, Kevin Feyen, and Elizabeth Widdicombe; editors Christine Brune, Nancy Fleming, Tracey Kuehn, Betty Probert, Trish Morgan, and Dora Figueiredo; sales and marketing colleagues Kate Nurre, Carlise Stembridge, Tom Kling, Lindsay Johnson, Mike Krotine, Kelli Goldenberg, Jen Cawsey, and Janie Pierce-Bratcher; media specialists Rachel Comerford, Gayle Yamazaki, Andrea Messineo, and Pepper Williams; and special guest Jennifer Peluso (Florida Atlantic University). The input and brainstorming during this meeting of minds gave birth, among other things, to LaunchPad’s new “Immersive Learning: How Would You Know?” activities and the text’s improved and expanded system of study aids.

Publisher Rachel Losh has been a valued team leader, thanks to her dedication, creativity, and sensitivity. Rachel has overseen, encouraged, and guided our author-editor team. Media Editor Lauren Samuelson helped envision our new “Immersive Learning: How Would You Know?” activities and directed all the details of their production. Executive Media Editor Rachel Comerford and Media Editor Laura Burden expertly coordinated production of the huge collection of media resources for this edition. Betty Probert efficiently edited and produced the Instructors’ Resources, Lecture Guides, Test Bank, and Study Guide and, in the process, also helped fine-tune the whole book. Editorial Assistant Katie Pachnos provided invaluable support in commissioning and organizing the multitude of reviews, sending information to instructors, and handling numerous other daily tasks related to the book’s development and production. Lee McKevitt did a splendid job of laying out each page. Robin Fadool and Candice Cheesman worked together to locate the myriad photos. Art Manager Matthew McAdams coordinated our working with artist Evelyn Pence to create the lovely new chapter openers.

Tracey Kuehn, Director of Content Management Enhancement, displayed tireless tenacity, commitment, and impressive organization in leading Worth’s gifted artistic production team and coordinating editorial input throughout the production process. Project Editor Robert Errera and Senior Production Manager Sarah Segal masterfully kept the book to its tight schedule, and Director of Design, Content Management Enhancement Diana Blume skillfully directed creation of the beautiful new design and art program. Production Manager Stacey Alexander, along with Supplements Project Editor Julio Espin, did their usual excellent work of producing the print supplements.

Christine Brune, chief editor for all 10 editions, is a wonder worker. She offers just the right mix of encouragement, gentle admonition, attention to detail, and passion for excellence. An author could not ask for more. Development Editor Nancy Fleming is one of those rare editors who is gifted both at “thinking big” about a chapter—and with a kindred spirit to our own—while also applying her sensitive, graceful, line-by-line touches. Development Editors Trish Morgan and Danielle Slevens amazed us with their meticulous focus, impressive knowledge, and deft editing. And Deborah Heimann did an excellent job with the copyediting.

To achieve our goal of supporting the teaching of psychology, this teaching package not only must be authored, reviewed, edited, and produced, but also made available to teachers of psychology. For their exceptional success in doing that, our author team is grateful to Worth Publishers’ professional sales and marketing team. We are especially grateful to Executive Marketing Manager Kate Nurre and Senior Marketing Manager Lindsay Johnson, both for their tireless efforts to inform our teaching colleagues of our efforts to assist their teaching, and for the joy of working with them.

At Hope College, the supporting team members for this edition included Kathryn Brownson, who researched countless bits of information and proofed hundreds of pages. Kathryn is a knowledgeable and sensitive adviser on many matters, and Sara Neevel is our high-tech manuscript developer, par excellence. At the University of Kentucky, Lorie Hailey has showcased a variety of indispensable qualities, including a sharp eye and a strong work ethic.

Again, I [DM] gratefully acknowledge the editing assistance and mentoring of my writing coach, poet Jack Ridl, whose influence resides in the voice you will be hearing in the pages that follow. He, more than anyone, cultivated my delight in dancing with the language, and taught me to approach writing as a craft that shades into art. Likewise, I [ND] am grateful to my intellectual hero and mentor, Roy Baumeister, who taught me how to hone my writing and embrace the writing life.

After hearing countless dozens of people say that this book’s resource package has taken their teaching to a new level, we reflect on how fortunate we are to be a part of a team in which everyone has produced on-time work marked by the highest professional standards. For their remarkable talents, their long-term dedication, and their friendship, we thank John Brink, Thomas Ludwig, and Richard Straub. With this new edition, we also welcome and thank Sue Frantz for her gift of instructors’ resources.

Finally, our gratitude extends to the many students and instructors who have written to offer suggestions, or just an encouraging word. It is for them, and those about to begin their study of psychology, that we have done our best to introduce the field we love.
