What kinds of childrearing practices foster the development of helping, sharing, and other prosocial behaviors? What roles do biology and culture play in the development of prosocial behavior? This book reviews and summarizes scholarly research that has been devoted to the development of prosocial behavior in children, and examines the various factors and influences that contribute to children's prosocial development, including the media, parents, peers, biology, culture, personal characteristics, and situational determinants. The authors argue that prosocial behavior can be learned and is modifiable, and they suggest techniques for parents, teachers and others to enhance prosocial development. They attempt to communicate the advances in the study of prosocial development that have taken place over the past decade and highlight questions previously unaddressed by researchers, and suggests areas for future work. This text is well-suited for undergraduate and graduate courses in child development and social psychology.
