Abstrakt

The aim of the present paper is to construct a model of formation of a cognitive representation of the category. The task was accomplished on the basis of a computer simulation of categorization adjusted to the results of empirical studies. The process of formation of a cognitive structure of the category was expressed in terms of the exemplar theory of categorization and in precisely defined relations of similarities between the perceived stimuli. The analysis of the process was carried out according to the optimization procedure that had been worked out. The procedure was applied to the results of experimental studies on perception categorization.

The optimization procedure revealed the inner, unobservable mechanism of formation of a cognitive structure of the outward experimental environment expressed by the dynamics of changes in the similarities between the categorized stimuli. The results of the studies were interpreted in terms of the cognitive-motivation conception of similarity ⟨Falkowski 1990a⟩, the theory of the cognitive dissonance ⟨Festinger 1957⟩ and the ecological theory of perception ⟨Gibson 1979⟩.
