A creative problem solving procedure (I.N. Semionov, V.K. Zaretsky) has been used for the study of 41 patients with psychological (psychopathical) disturbances of historical and excitable types. It has been possible to experimentally prove the hypothesis that decreased productivity and peculiar thinking in anomalous individuals are determined by disturbed balance between reflexive and emotional regulation of thinking which results in domination of meaning over content. Differences in mechanisms of disturbed thinking in the studied groups of patients have been established.
