Volume 46 of Advances in Child Development and Behavior includes chapters that highlight some the most recent research in this area. A wide array of topics are discussed in detail, including internalization and socialization, infants' discovery of structure, adolescents' theories of the commons, lesbian and gay parenting, early childhood and family interventions, predicting aggression, causal inference in early development, pubertal development, the impact on children of parental deployment to war, vocabulary development for English learners in the early grades, and adaptive tool-use in early childhood. Each chapter provides in-depth discussions, and this volume serves as an invaluable resource for developmental or educational psychology researchers, scholars, and students.
