Abstract: | Correction Notice: An erratum for this article was reported in Vol 78(4) of Journal of Personality and Social Psychology (see record 2007-17406-001). In this article, Table 3 (p. 987) contained an error. The row "Number of subgroups" was inadvertently omitted. The corrected table appears in this erratum.] Three experiments showed increases in the perceived variability of social groups after perceivers received stereotype-incongruent information about group members. In Experiment 1, participants generated flatter distributions after exposure to incongruent information, compared with equally deviant congruent information, in the form of typical verbal materials. Experiment 2 indicated similar changes in dispersion after the presentation of numeric information about a single group member. In Experiment 3, the authors manipulated cognitive load at encoding or at the time group judgments were requested. Under conditions of cognitive constraint, stereotype-incongruent information ceased to promote more dispersed group representations. These results are consistent with the idea that incongruent information triggers more deliberative and comprehensive retrieval and generation of exemplars. The authors discuss the implications of these findings for stereotype change. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
