In the past decade, the topic of emotion-related regulation has been a topic of considerable interest to developmental scientists. This is partly due to the resurgence of interest in emotion among psychologists in the past two decades, and partly due to the purported role of emotion regulation in children’s socioemotional development and adjustment. In this chapter, we first discuss conceptualizations of emotion-related regulation or control and their predicted
relations with social competence and adjustment. Next, we selectively review research on the relation between emotion-related regulation or control and social functioning during infancy and toddlerhood, as well as childhood. Finally, the potential role of parental socialization in the development of regulation and regulated behavior (e.g., social competence and adjustment) is discussed, and illustrative research is reviewed. Throughout, research from the laboratories in which the authors have worked is emphasized, although other related work sometimes is reviewed.
