The commission of socially dangerous acts always sparks a public outcry, and special attention and close interest are noted when the perpetrator suffers from a mental disorder. As far as the mental disorders diagnosed in this group of individuals are concerned, schizophrenia ranks among the first, and the research of its complex clinical picture is a promising direction for studying the features of delinquent behavior. The relevance of the study lies in the investigation of the nature of cognitive activity and its relationship with the clinical manifestations of schizophrenia. The purpose of the work was to analyze cognitive activity in schizophrenia patients who committed socially dangerous acts and identify their relationship with clinical manifestations of schizophrenia. The study was performed on 22 examinees of the department of inpatient forensic psychiatric examination for persons in custody who committed socially dangerous acts against the health and life of an individual, and 26 patients who were being treated in a general psychiatric department. According to the criteria of ICD-10, all subjects were diagnosed with paranoid schizophrenia at the stage of inpatient remission. In all participants of the experiment, the clinical picture of schizophrenia using the Positive and Negative Syndrome Scale (PANSS) was assessed, and the analysis of cognitive activity by means of the method of discrimination of properties of concepts was carried out. It has been established that the clinical manifestations of schizophrenia are characterized by diversity, persistence, and independence from committed aggressive delicts, and the cognitive activity of such patients is characterized by pronounced subjectivity and moderate realism, which makes their behavior peculiar, rigid to external influence, and extremely persistent in relation to their own goals.
