Social Identity Theory
Social identity theory is an interactionist social psychological theory of the role of self conception and associated cognitive processes and social beliefs in group processes and intergroup relations. Originally introduced in the 1970s primarily as an account of intergroup relations, it was significantly developed at the start of the 1980s as a general account of group processes and the nature of the social group. Since then, social identity theory has been significantly extended through a range of sub theories that focus on social influence and group norms, leadership within and between groups, self enhancement and uncertainty reduction motivations, deindividuation and collective behavior, social mobilization and protest, and marginalization and deviance within groups. The theory has also been applied and developed to explain organizational phenomena and the dynamics of language and speech style as identity symbols. Chapter 1 provides a relatively comprehensive and accessible overview of social identity theory, with an emphasis on its analysis of intergroup conflict.
