This is an exciting time in the field of child development. The past decade has brought new theories, new ways of thinking, new areas of research, and innumerable new findings to the field. We originally wrote How Children Develop to describe this ever improving body of knowledge of children and their development and to convey our excitement about the progress that is being made in understanding the developmental process. We are pleased to continue this endeavor with the publication of the Fourth Edition of How Children Develop. —From the Preface

As new research expands the field’s understanding of child and adolescent development, the authors of How Chil- dren Develop continue their commitment to bringing the story of today’s developmental science to the classroom in a clear and memorable way. Joined in this Fourth Edition by Jenny Saffran of the University of Wisconsin–Madison, they maintain their signature emphasis on the “Seven Classic Themes” of development, which facilitates students’ understanding by highlighting the fundamental questions posed by investigators past and present. The new and ex- panded coverage in the Fourth Edition spans a wide range of topics—from broad areas like the epigenetic aspects of development, the links between brain function and behavior, and the pervasive influence of culture to specific subjects such as the mechanisms of infants’ learning, the effects of math anxiety, and the rapidly growing influence of social media in children’s and adolescents’ lives. This edition also features the highly anticipated debut of Launch- Pad, an online learning system that features Worth Publishers’ celebrated video collection; the full e-Book of How Children Develop; and the LearningCurve quizzing system, which offers students instant feedback on their learning.

Coverage of contemporary developmental science is very important to me. I prefer a text that describes the relevant research and is updated regularly. I find How Children Develop to be very good in this area, as all of the authors are primarily researchers.

—Jeffery Gagne, University of Texas at Arlington

I highly recommend this textbook. The main strengths are up-to-date research with clear descriptions of study methods and findings as well as excellent real-world examples that get students interested in a topic so that they are excited enough to read about the research and evidence that support real-world developmental phenomenon. I do not think the text has a major weakness.

—Katherine O’Doherty, Bowdoin College

Since its inception, I think that How Children Develop is the best child development textbook available. I would not hesitate to use it again in my classes.

—Richard Lanthier, George Washington University
