[Behavioral tactics of schizophrenic patients and psychopathic personalities in a probabilistic setting]

In experiments on structural disturbances of prognostication in psychopathic personalities and schizophrenic patients with psychopathlike disorders on the model of "probable prognosis" the study of 2 situations was attempted: the prognosis made by the examinee of changes in the environment and the prognosis in conditions of interaction with the "opponent". The studies demonstrated the influence of different tasks on the activity and varying degree of motivation on the tactics of behaviour in probable situations. The data obtained permit to evaluate in a new light the hypotheses of disturbed probable structures of the past experience. It is concluded that at least 3 determinants should be analyzed: tasks of activity, motivation and probable characteristics of events. New facts have been obtained, concerning the disturbed prognostication in psychopathic personalities under conditions of increased significance of signals.
