This engaging, authoritative text synthesizes a vast body of research on how young children develop the ability to understand, express, and manage their emotions, as well as the impact of these capacities on relationships, school readiness, and overall well-being. Illustrated with vivid vignettes, the book explains specific ways that parents, teachers, and education systems can foster or hinder emotional competence, and reviews relevant assessments and interventions. Compelling topics include emotion regulation as both product and process, cultural variations in emotion socialization, the expression of empathy and self-conscious emotions, risk factors for delays in emotional development, and connections between emotional competence and social-emotional learning (SEL). Almost entirely new, this book replaces Susanne A. Denham's influential earlier work, Emotional Development in Young Children.
