Abstract

This study explored whether or not the internal structure of a category representation can be changed by the prior context. In a preliminary survey, natural categories were divided into two groups of categories, internal or external category, as proposed by Barr & Caplan(1987). In Experiment 1, interactions between context and category types were examined by manipulating con: text conditions: typical, atypical, and control. Experiment 2 examined whether or not the typicality gradedness can be reversed in both types of categories. These experiments showed that the internal category maintained more stable structure than did the external category. Experiment 3 explored the differences between the internal and the external category in the activation processes of internal and external features. Color-naming time was not changed by context manipulations but by its typicality in the internal category. In contrast, color-naming time was influenced by context manipulations after some delay in the external category. This study suggests that category representation has stable internal structures, as opposed to previous studies which reported prevailing contextual effects.
