PREFACE

If human development were simple, universal, and unchanging, there would be no need for a new edition of this textbook. Nor would anyone need to learn anything about human growth. But human development is complex, varied, and never the same.

This is evident to me in small ways as well as large ones. Yesterday, I made the mistake of taking two of my grandsons, aged 6 and 7, to the grocery store, asking them what they wanted for dinner. I immediately rejected their first suggestions—doughnuts or store-made sandwiches. But we lingered over the meat counter. Asa wanted hot dogs and Caleb wanted chicken. Neither would concede.

At least one universal is apparent in this anecdote: Grandmothers seek to nourish grandchildren. But complexity and variability were evident in two stubborn cousins and one confused grandmother.

This small incident is not unlike the headlines in today’s newspaper. Indeed, other developmental questions seem more urgent now, interweaving what is universally true about humans with what is new and immediate, balancing them in order to move forward with our public and personal lives. I found a compromise for dinner—chicken hot dogs, which both boys ate, with whole wheat bread and lots of ketchup. I do not know the solutions to public dilemmas such as climate change, immigration, gun violence, and systemic racism, but I believe that a deeper and more accurate understanding of human development might help.

That is why I wrote this eleventh edition, which presents both the enduring and the current findings from the study of child and adolescent development. Some of those findings have been recognized for decades, even centuries, and some are new, as thousands of scientists study how humans grow and change with new circumstances. I hope they will help us with the public and private aspects of our lives.

What’s New in the Eleventh Edition? New Material Every year, scientists discover and explain more concepts and research. The best of these are integrated into the text, with hundreds of new references on many topics, including epigenetics at conception, prenatal protections, infant nutrition, autism spectrum disorder, attachment, high- stakes testing, drug addiction and opioid-related deaths, sex education, and diversity of all kinds —ethnic, economic, gender, and cultural. Cognizant of the interdisciplinary nature of human development, I include recent research in biology, sociology, education, anthropology, political science, and more—as well as my home discipline, psychology.

What Can You Learn? Scientists first establish what is, and then they try to change it. In one recent experiment, Deb Kelemen (shown here) established that few children under age 12 understand a central concept of evolution (natural selection). Then she showed an experimental group a picture book illustrating the idea. Success! The independent variable (the book) affected the dependent variable (the children’s ideas), which confirmed Kelemen’s hypothesis: Children can understand natural selection if instruction is tailored to their ability.

Genetics and social contexts are noted throughout. The interaction of nature and nurture is discussed in many chapters, because neuroscience relates to every aspect of life. Among the many topics described with new research are the variations, benefits, and hazards of breast- feeding, infant day care, preschool education, single parenthood, exercise, vaccination, same-sex marriage—always noting differences, deficits, and resilience.

No paragraph in this edition is exactly what it was in the tenth edition. To help professors who taught with the earlier texts, or students who have friends who took the course a few years ago, here are some highlights of the updates:

Is She Awake? This 36-year-old mother in Hong Kong put her 7-month-old baby on her back, protecting her from SIDS as the Chinese have done for centuries. However, the soft pillow and comforter are hazards. Will she carry the baby to a safe place before she falls asleep?

Universal Morality Remarkable? Not really. By the end of middle childhood, many children are eager to express their moral convictions, especially with a friend. Chaim Ifrah and Shai Reef believe that welcoming refugees is part of being a patriotic Canadian and a devout Jew, so they brought a welcoming sign to the Toronto airport where Syrian refugees (mostly Muslim) will soon deplane.

New Inside the Brain Feature

Since new discoveries abound almost daily in the field of neuroscience, I have added Inside the Brain features to several chapters, exploring topics such as the intricacies of prenatal and infant brain development, brain specialization and speech development, and brain maturation and emotional development.

New and Updated Coverage of Neuroscience Inclusion of neuroscience is a familiar feature of this book. In addition to the new Inside the Brain features, I include the latest, cutting-edge research on the brain in virtually every chapter, often enhancing it with charts, figures, and photos to help students understand the brain’s inner workings. A list highlighting this material is available at macmillanlearning.com.

New Developing Lives Developing Lives is a robust and sophisticated interactive experience in which each student “raises” a virtual child from sperm-and-egg to teenager—fully integrated into LaunchPad. With Developing Lives, each student creates a personal profile, selects a virtual partner (or chooses to be a single parent), and marks the arrival of their newborn (represented by a unique avatar based on the parents’ characteristics). As the child grows, the student responds to events both planned and unforeseen, making important decisions (nutrition choices, doctor visits, sleeping location) and facing uncertain moments (illness, divorce, a new baby), with each choice affecting how the child grows. Throughout, Developing Lives deepens each student’s attachment and understanding of key concepts in the field with immediate, customized feedback based on child development research. It integrates more than 200 videos and animations and includes quizzes and essay questions that are easy to assign and assess.

New Integration with LaunchPad Throughout the book, the margins include LaunchPad call-outs to online videos about people in a particular context or key scientists who might become role models. For example, Susan Beal, the Australian scientist who revolutionized our understanding of SIDS (sudden infant death

http://www.macmillanlearning.com
syndrome) and infant sleep is shown. The video demonstrates that she is not an aloof expert, but a wife and mother, like many students and their relatives. Application to Developing Lives (described above) and Data Connections activities (described below) are also highlighted for the reader.

Renewed Emphasis on Critical Thinking and Application in the Pedagogical Program We all need to be critical thinkers. Virtually every page of this book presents questions as well as facts. A new marginal feature, Think Critically, encourages student reflection and analysis. There are no pat answers to these questions: They could be used to start a class discussion or begin a long essay.

Every chapter begins with a few What Will You Know? questions, one for each major heading. Of course, much of what readers will learn will be reflected in new attitudes and perspectives— hard to quantify. But these What Will You Know? questions are intended to be provocative and to pose issues that the students will remember for decades.

In addition, after every major section, What Have You Learned? questions appear. They are designed to help students review what they have just read, a pedagogical technique proven to help retention. Ideally, students will answer these learning objective questions in sentences, with specifics that demonstrate knowledge. Some items on the new lists are straightforward, requiring only close attention to the chapter content. Others require comparisons, implications, or evaluations.

Key terms are indicated with bold print and are defined in the margins as well as in the glossary, because expanded vocabulary aids expanded understanding. To help students become better observers, occasional Observation Quizzes accompany a photo or figure. And, since many students reading this book are preparing to be teachers, health care professionals, police officers,

or parents, every chapter contains Especially For questions that encourage students to apply important developmental concepts just as experts in the field do.

As a professor myself, I continue to seek ways to deepen knowledge. Cognitive psychology and research on pedagogy finds that vocabulary, specific applications details, and critical thinking are all part of learning. These features are designed to foster all four.

Updated Features Online Data Connections Activities Understanding how scientists use data helps students realize that the study of human development is much more than personal experience and common sense. Evidence sometimes contradicts myths and assumptions, and sometimes it confirms them. This edition continues to offer interactive activities—many of which have been updated with the latest available data—to allow students to interpret data on topics ranging from infant breast-feeding to adolescent risk- taking.

For example, students discover how U.S. poverty rates are worse for children than for adults, data that may be surprising. These interactive activities advance active thinking, deepening their understanding of the need for data. Instructors can assign these activities in the online LaunchPad that accompanies this book.

Opposing Perspectives, A View from Science, and A Case to Study Special topics and new research abound in childhood and adolescent development. This edition

of The Developing Person Through Childhood and Adolescence includes boxed features in every chapter. Opposing Perspectives focuses on controversial topics—from prenatal sex selection to e-cigarettes. Information and opinions on both sides of each issue are presented, so students can weigh evidence, assess arguments, and reach their own conclusions while appreciating that an opposite conclusion also has merit. A View from Science explains research in more detail, illustrating the benefits of the scientific method. A Case to Study focuses on particular individuals, helping students to recognize the personal implications of what they learn.

Infographics Information is sometimes better understood visually and graphically. Carefully chosen, updated photos and figures appear on almost every page, with captions that explain and increase knowledge. In addition, every chapter includes a full-page, graphical depiction.

These infographics explain key concepts, from brain development to school attendance rates, often with data that encourage students to think of other nations, other cultures, other times. My two awesome editors and I have worked closely with noted designer Charles Yuen to create these infographics, hoping they reinforce key ideas.
