Unique in its dual focus on emotion and lifespan development, this text weaves together theory, research, and practical clinical implications for fostering children's emotional well-being. The author examines how emotions are experienced, expressed, understood, and regulated from infancy through later adulthood. Chapters highlight the interrelated influences of temperament, neurobiology, and the social environment, and distinguish universal processes from those that vary across cultures. The book presents current knowledge about specific emotions, probes the causes and consequences of emotional maladjustment, and reviews evidence-based and promising interventions.
