"Experiences with peers have a tremendous impact on children's social, emotional, and cognitive development. Yet until now, no single volume has synthesized the growing body of knowledge on peer relations from infancy through adolescence. This comprehensive, authoritative handbook fills that gap. Leading researchers cover the breadth of theories, methods, and empirically based findings on the dynamics of peer interactions and relationships and their crucial role in children's well-being and adjustment." "This timely reference belongs on the shelves of developmental, clinical, school, and educational psychologists; counselors; and other researchers and practitioners interested in socioemotional development. IT will serve as a highly informative text in graduate-level courses."--Jacket.
