A study is described where the author has defined and experimentally interpreted the notion of the logical-psychological dimension (LPD) of the microsystemic model in which the psychological proper, the need-motivational, and computer-reproducible logical components of thinking are non-disjunctively (in the sense of Rubinstein-Brushlinsky) combined and brought apart. The function of the first component consisted in prediction and in organization of search, of the second - in generation of systems adequately realizing the prediction of acts (algorythmic acts included). In LPD topological elements are primary in relation to the algorythmic ones which constitute the basis of computer's programs. Some possibilities and limitations for reproduction of psychological phenomena by computers are discussed.
