n. a set of cognitive generalizations (e.g., beliefs, expectations) about the qualities and characteristics of the members of a group or social category. Stereotypes, like schemas, simplify and expedite perceptions and judgments, but they are often exaggerated, negative rather than positive, and resistant to revision even when perceivers encounter individuals with qualities that are not congruent with the stereotype (see negative stereotype; positive stereotype; prejudice). See also exemplar theory; gender stereotype; kernel-of-truth hypothesis; sex-role stereotype. —stereotypicadj.
