Identity theory and social identity theory

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.
