Stereotypes: static abstractions or dynamic knowledge structures?
Stereotypes have been assumed to be long-lasting knowledge structures that persist even in the face of contrary evidence. However, there is almost no within-participant research relevant to this assumption. The authors describe 4 studies (N=267), the first 3 of which assessed within-participant stereotype stability over a few weeks with measures of stereotypic trait verification, typicality ratings of exemplar sets, and exemplar retrieval. In the 4th study, the authors manipulated context stability. Overall, results showed only low-to-moderate stereotype stability. The stability obtained was a function of the perceived centrality of traits or exemplars and of context constancy. The authors discuss the implications of these results for abstractionist, exemplar, mixed, and connectionist models and identify possible mechanisms that underlie within-participant stereotype instability.
