Interaction in Social Networks

Abstract

Social network research constitutes one of the most rapidly expanding academic areas and is emerging as an increasingly popular paradigm for social psychological inquiry. A social network perspective emphasizes the importance of social ties among actors in shaping individual behavior, and at the same time, focuses on the processes by which networks emerge out of, and mold, social interaction. Here we discuss basic principles and key theories associated with a network framework, and describe and illustrate elementary concepts, such as “weak ties” and centrality. We review applications in such areas as friendship, aggression, health, social support, social influence, small groups, close relationships, and the growing field of Internet network ties. We end with a call for greater attention to the “dark side” of network connections, a focus on the dynamic mechanisms by which networks influence microlevel behavior, and increased integration of network scholarship with core social psychology theories and constructs.
