Self-stereotyping-Self-stereotyping-Within social psychology self-stereotyping (or autostereotyping) is a process described as part of social identity theory (SIT) and, more specifically, self-categorization theory (SCT). Self-stereotyping occurs when an individual integrates commonly held characterizations (i.e. stere...

Self-stereotyping-Description-Self-stereotyping has also been characterized as an overlap between how a person represents their ingroup and how they represent the self. Prior to self-stereotyping, one experiences depersonalization, the process of shedding one's unique identity to merge it with the group identity of the...
