The problem of similarity assessment in categorization process



In the article different approaches to the role of similarity in categorization process are considered. The following hypothesis is verified in the series of experiments. If some internal human capacity to determine similarity could be considered as the foundation of categorization process then mental structures obtained from the data in categorization (free sorting) task and in similarity judgment task would be identical. The data received call into question the assumption about similarity judgments as the basis of categorization.
