Aspects of identity: From the inner-outer metaphor to a tetrapartite model of the self

We review a program of research on identity orientations – the relative importance or value that individuals place on various identity attributes when constructing their self-definitions. We first provide a brief history of the development of our measure of identity orientations – the Aspects of Identity Questionnaire (AIQ) – after which we present our tetrapartite model of the self that distinguishes among individual, relational, public, and collective aspects of identity. We then review previous research on how the four identity orientations uniquely influence cognition, emotion, and behavior, and close by highlighting what we see as interesting and important directions for future research.
