Problems of categorization: Theory and applications
(RESUME)

Categorization must not be identified with classification. The author defines it as an arrangement of both present in and entering into the subject information on every cognitive level. Two descriptive notions are introduced for analytical purposes: "categorical system", and "sets of unintersecting (discernible by the subject) classes". Such sets may be viewed by the subject as either incomplete (allowing inclusion of additional classes) or complete. Viewing sets as complete may hinder for the subject opening of new possibilities when making a decision or solving a problem. Creative attitude towards established categorical systems and sets as well as corresponding transformation of them provide for adequate categorization. The suggested approach sheds light on certain well-known facts, among them - the phenomenon of comprehension. Some pedagogical implications are considered.
