Book excerpt: This book addresses cultural variability in children’s social worlds, examining the acquisition, development, and use of culturally relevant social competencies valued in diverse cultural contexts. It discusses the different aspects of preschoolers’ social competencies that allow children – including adopted, immigrant, or at-risk children – to create and maintain relationships, communicate, and to get along with other people at home, in daycare or school, and other situations. Chapters explore how children’s social competencies reflect the features of the social worlds in which they live and grow. In addition, chapters examine the extent that different cultural value orientations manifest in children’s social functioning and escribes how parents in autonomy-oriented cultures tend to value different social skills than parents with relatedness or autonomous-relatedness orientations. The book concludes with recommendations for future research directions. Topics featured in this book include: Gender development in young children. Peer interactions and relationships during the preschool years. Sibling interactions in western and non-western cultural groups. The roles of grandparents in child development. Socialization and development in refugee children. Child development within institutional care. Children’s Social Worlds in Cultural Context is a valuable resource for researchers, clinicians/practitioners, and graduate students in developmental psychology, child and school psychology, social work, cultural anthropology, family studies, and education.
