 Turner et al.’s (1987) “self-categorization theory” provides a more specific characterization of self-perception, or self-definition, as a system of cognitive self-schemata that filter and process information. Such schemata result in a representation of the social situation that guides the choice of appropriate action. This system has at least two major components, i.e., social and personal identity. Social identity refers to self-descriptions related to group memberships. Personal identity refers to self-descriptions such as individual character traits, abilities, and tastes. Although personal and social identities are mutually exclusive levels of self-definition, this distinction must be taken as an approximation (in that there are many interconnections between social and personal identities). It is, however, important to recognize that we often perceive ourselves primarily in terms of our relevant group memberships rather than as differentiated, unique individuals. So—depending on the situation—personal or group identity will become salient (Brewer 1991).
