DescriptionThis dissertation proposes and tests the diagnosticity and judgment task model of person perception. This decision tree model of reliance on stereotypes and individuating information in impression formation makes a priori predictions regarding in what situations perceivers will rely on individuating information, in what situations they will rely on stereotypes (i.e., category information), and in what situations they will rely on both sources of information. The central tenet of the model is that the diagnosticity (i.e., relevance, usefulness) of the individuating information and the type of judgment task jointly influence reliance on stereotypes and individuating information in stereotype-relevant target evaluations. In the present research, the model’s two main a priori hypotheses were tested: (1) In the presence of highly diagnostic individuating information and category information, perceivers should rely exclusively on individuating information in target evaluations, regardless of the judgment task at hand; and (2) in the presence of somewhat diagnostic information and category information, perceivers should rely exclusively on individuating information in trait ratings, but on stereotypes and individuating information in occupational suitability judgments and target-relevant predictions. The first hypothesis was supported, but the second was not. These results are discussed in the context of previous relevant research.
