This volume provides a developmental perspective of the regulation and dysregulation of emotion, in particular, how children learn about feelings and how they learn to deal with both positive and negative feelings. Emotion regulation involves the interaction of physical, behavioural and cognitive processes in response to changes in one's emotional state. The changes can be brought on by factors internal to the individual (e.g. biological) or external (e.g. other people). Featuring contributions from leading researchers in developmental psychopathology, the volume concentrates on theories and data concerning the development of emotion regulation with an emphasis on both intrapersonal and interpersonal processes. Original conceptualizations of the reciprocal influences among the various response systems - neurophysiological-biochemical, behavioral-expressive, and subjective-experiential - are provided, and the individual chapters address both normal and psychopathological forms of emotion regulation, particularly depression and aggression, from infancy through adolescence. This book will appeal to specialists in developmental, clinical and social psychology, psychiatry, education, and others interested in understanding the developmental processes involved in the regulation of emotion over the course of childhood.
