The Evaluation Apprehension is the theory in which a person is aware that the social rewards (apprehension) that he/she will receive will be based on the evaluation by people.
The theory of Evaluation Apprehension was theorized by Cottrell in 1972. According to Cottrell, the performances of people can be enhanced or impaired by the evaluation of others.
The stereotype threat is the situation in which a negatively stereotyped group evaluates the person's performance based on certain stereotypes. It is a part of evaluation apprehension.
