John Bates

JOHN E. BATES, Ph.D., Indiana University

Phone: (812) 855-8693
John E. Bates, Ph.D is a Professor in the Department of Psychological and Brain Sciences and the Director of Clinical Training at Indiana University. Using longitudinal data, his research focuses on the development of problem behaviors and social competencies in childhood and their interplay with family interaction processes, child temperament and affective characteristics. This work has found evidence that early child temperament and mother-child interactions are related to children's adjustment later in development. Recently, Bates has been investigating sleep patterns among children and their impact on daily adjustment.


KENNETH A. DODGE, Ph.D., Duke University

Phone: (919) 613-9303
Kenneth A. Dodge, Ph.D. is the William McDougall Distinguished Professor of Public Policy and Professor of Psychology and Neuroscience at Duke University. He is also a faculty fellow at the Duke Center for Child and Family Policy, which he founded in 1999. Dodge is a leading scholar in the development and prevention of aggressive and violent behaviors. His work provides a model for understanding how some young children grow up to engage in aggression and violence and provides a framework for intervening early to prevent the costly consequences of violence for children and their communities. Dodge led the research and development of the Family Connects model, an evidence-based and successfully demonstrated program that connects parents of newborns to the community resources they need through postpartum nurse home visits. The model has been shown to improve maternal and child health outcomes, including lowering rates of Child Protective Services investigations for suspected child abuse or neglect. Dodge has published more than 500 scientific articles which have been cited more than 128,000 times.


GREGORY S. PETTIT, Ph.D., Auburn University

Phone: (334) 826-8326
Gregory S. Pettit, Ph.D, is a Human Sciences Professor Emeritus in the Department of Human Development & Family Science at Auburn University. His research concentrates primarily on the development of social competence from childhood through early adulthood. He is particularly focused on the mechanisms by which family, peer, and romantic interactions affect development and how risk and protective factors moderate these relationships. Recently, Pettit’s work has focused on factors contributing to youths’ receptivity to parental guidance and protection.
