Social Identity Theory suggests that individuals classify themselves and others into various social categories (Ashforth and Mael, 1989). This categorization is comparative when describing oneself in relation to other groups or organizations. The authors suggest that this social identification derives from a concept of group identification. How does one socially identify him/herself in the context of a organization or group? How does social identification affect self-esteem, and what affect does out-group awareness have on the perception of one''s in-group, if any? References: Ashforth, B., & Mael, F. (1989).
