In this extensively revised edition, Martha Ann Bell and her contributors synthesize the newest research on how cognitive and emotional processes influence each other in child development. Historically, research in child development has treated cognitive processes as separate and distinct from social-emotional processes. However, many of the factors that influence self-regulation are also closely linked to cognitive development. For example, genetics, prenatal environment, relationships, language, and physiological processes are all links between emotion and cognition in child development. The first edition of this volume greatly increased our understanding of emotion-cognition integration. This second edition incorporates new longitudinal research demonstrating this integration during infancy and throughout childhood. Chapters incorporate new research methods based on technological advances that have greatly enhanced our ability to examine early human brain development. The resulting volume is a critical read for those interested in understanding how brain development influences our behavior and social interactions.
