THE FORMATION OF CONCEPTS UNDER THE PRINCIPLE OF FAMILY RESEMBLANCE
The research data of concept formation under the principle of family resemblance is presented. The author analyzes the data, received using a reversal shift method. It is shown that concepts of this type are formed by means of two systems, one of which is explicit and is based on the rules, and another is implicit and based on perceptual similarity. The researcher conducts a qualitative analysis of mistakes and mechanisms of their origin. The research helps to reveal indirect evidence for the existence of two memory systems. The author suggests that the relation between these systems may be of a competitive nature. Recurring errors are considered as an indicator of continuous parallel information processing.
