To solve this problem, author John Santrock has sought the input ofleading experts about content in a number of areas of children’s development. These experts have provided detailed evaluations and recommendations intheir area(s) of expertise.The following individuals were among those who served as expert consultants for one or more of the previous editions of this text:Urie Bronfenbrenner, Cornell UniversityDiana Baumrind, University of California–BerkeleyTiffany Field, University of MiamiScott Johnson, University of California–Los AngelesNel Noddings, Stanford UniversityRoss Thompson, University of California–DavisSandra Graham, University of California–Los AngelesJames Marcia, Simon Fraser UniversityJohn Bates, Indiana UniversityFlorence Denmark, Pace UniversityRosalind Charlesworth, Weber State UniversityDavid Sadker, The American University–Washington DCMarilou Hyson, University of PennsylvaniaAlgea Harrison-Hale, Oakland UniversityCampbell Leaper, University of California-Santa CruzJanet DiPietro, Johns Hopkins UniversityAllan Wigfield, University of Maryland–College ParkBarbara Pan, Harvard UniversityPeter Scales, Search InstituteFollowing are the expert consultants for the thirteenth edition, who (like those of previous editions) literally represent a Who’s Who in the field of childand adolescent development.Elizabeth Trejos-CastilloDr. ElizabethTrejos-Castillo is an expert on diversity, culture, andadolescent development. She currently is a professor inHuman Development and Family Studies at Texas TechUniversity. Her research interests mainly focus onrisk-taking and adjustment in youth as well as generational,individual and contextual effects in adolescent development. Her researchapproach is rooted in psychology, sociology, and human development usingcross-cultural and evidence-based research methodologies. Dr. TrejosCastillo is an associate editor of The Journal of Early Adolescence.“I’m definitely impressed with the vast literature covered in bothChapters 13 and 16 . . . the scholarly work and theories described arewell illustrated using cross-cultural/cross-national studies which providestudents with a well-rounded, inclusive view of development of childrenand adolescents around the globe. . . . The author provides a wellbalanced literature review that discusses seminal work and at the sametime introduces the most up-to-date scholarship. . . . I personally enjoyvery much the conversational tone of the narrative and the easiness withwhich John Santrock connects and integrates different topics acrosschapters”—Elizabeth Trejos-CastilloDavid Moore Dr. Moore is a leading expert ongenetic/environmental influences on development and infant perceptual/cognitive development. He obtained aPh.D. in developmental and biological psychology fromHarvard University. After completing a postdoctoralfellowship at the City University of New York, he joinedthe faculties of Pitzer College and Claremont Graduate University, wherehe currently is a professor of psychology. His book, The Dependent Gene,was widely adopted for use in undergraduate education, was translatedinto Japanese, and was nominated for the Cognitive DevelopmentSociety’s Best Authored Volume award. Dr. Moore’s empirical researchhas produced publications on infants’ reactions to infant-directed speech,on the development of spatial cognition, and on infants’ rudimentaryxiiperception of numerical quantities. His theoretical writings have exploredthe contributions of genetic, environmental, and epigenetic factors tohuman development; his chapter “Genetics, Behavior Genetics, andEpigenetics” appeared in 2013 in the Oxford Handbook of DevelopmentalPsychology, and his new book on behavioral epigenetics was published byOxford University Press in 2014. He serves on the editorial board of ChildDevelopment Perspectives.“The narrative and perspective effectively reflect the latest and mostimportant research. . . . I think John Santrock has done a great job inciting the latest research. . . . his efforts to connect ideas across chapters,to connect developmental processes across different stages, and to connectthe information conveyed in the book to readers’ real lives will pay off.—David MooreElizabeth Gershoff Elizabeth Gershoff is aleading expert on the social contexts, especially familycontexts, of child and adolescent development. Sheobtained a Ph.D. in child development and familyrelationships from the University of Texas at Austinand currently is a professor in Human Developmentand Family Sciences there. Dr. Gershoff’s current research interests andexpertise center on four topics: (1) how parental discipline affects childand youth development; (2) how contexts of poverty, neighborhoods,schools, and cultures affect children, youth, and families; (3) how exposureto various forms of violence (from parents, communities, and terrorism)affect child and youth development; and (4) how enriched early childhoodeducational environments can improve the lives of low-income childrenand their families. She co-edited Societal Contexts of Child Development(2014), published by Oxford University Press.“The narrative and perspective reflect the latest and most importantresearch in the field. . . . the citations are current and reflect current theoryand recent findings. . . . readers will get a good overview of the topicsand studies. The sections on theories and research methods are strong.”—Elizabeth Gershoff
