Two experiments were conducted to examine the process of category judgement for each case belonging to ill-defined categories. After impression formation tasks were carried out by presenting 10 cases that were generated from combination of two personality traits, 40 university students were instructed to rate typicality of old and new cases. Experiment I (situation of case remembering) showed that (1) each stimulus dimension was additively integrated, (2) memory information concerning categories seemed to be the information about how each trait was weighted in integrating stimulus dimensions, rather than prototype or exemplar information, (3) the degree of membership for new cases was able to be inferred from this weighted information. However, experiment II (situation of case perception) suggested that the explanatory power of this category judgement model is not limitless but dependent on task demand. These results were discussed according to Nosofsky (1984) and Reed (1972).
