| Abstract: | The present study examined how prototypes, as organizational principles of knowledge about persons, affect attribute inference judgments. A distinction is drawn between bipolar and unipolar categories. Two questions are addressed: First, whether only one or both prototypes of bipolar categories like extraversion-introversion are activated in making inference judgments, and second, whether information about the applicability of a stimulus item to a target is processed differently than information about the inapplicability of the stimulus item. The results support the hypothesis that only one prototype is activated and that this is the affirmative one, irrespective of whether the stimulus information is applicable or inapplicable to the target person. The implications of these findings are discussed. |
