Peer relations in childhood have long been thought to affect adjustment and maladjustment across the lifespan. In his timely book, Schneider, an expert in the theory and applications of research into childhood peer relationships, provides an introductory overview of this area within developmental psychology. He looks at childhood friendships, enemies and peer social interaction in the context of their effect on children in school, at home and with relation to culture and gender differences. Finally the author examines the applications of much of modern-day research through community and treatment centres designed to improve peer relationships both for groups and for the individual.
