The concept of identity has become widespread within the social and behavioral sciences in recent years, cutting across disciplines from psychiatry and psychology to political science and sociology. All individuals claim particular identities given their roles in society, groups they belong to, and characteristics that describe themselves. Introduced almost 30 years ago, identity theory is a social psychological theory that attempts to understand identities, their sources in interaction and society, their processes of operation, and their consequences for interaction and society (...) from a sociological perspective. This book describes identity theory, its origins, the research that supports it, and its future direction. It covers the relation between identity theory and other related theories, as well as the nature and operation of identities. In addition, the book discusses the multiple identities individuals hold from their multiple positions in society and organizations as well as the multiple identities activated by many people interacting in groups and organizations. And, it covers the manner in which identities offer both stability and change to individuals. Written in an accessible style, Identity Theory makes, step by step, the full range of this powerful new theory understandable to readers at all levels. (shrink)

The article by Chung and Harris brings together an impressive array of literature to formulate a dynamic functional model of jealousy. There is much to like about the model. However, one concern is how it advances a theory of jealousy. Another concern is how the DFMJ operates over time, with different social groups, and cross-culturally. In general, however, the model offers a useful way to think about jealousy for the future.

In social psychology, we need to establish a general theory of the self, which can attend to both macro and micro processes, and which avoids the redundancies of separate theories on different aspects of the self. For this purpose, we present core components of identity theory and social identity theory and argue that although differences exist between the two theories, they are more differences in emphasis than in kind, and that linking the two theories can establish a more fully integrated (...) view of the self. The core components we examine include the different bases of identity (category/group or role) in each of the theories, identity salience and the activation of identities as discussed in the theories, and the cognitive and motivational processes that emerge from identities based on category/group and on role. By examining the self through the lens of both identity theory and social identity theory, we see how, in combination, they can move us toward a general theory of the self. (shrink)
