[Comparative study of features of the perceptive and intellectual activity of schizophrenic children]

A comparative study of the formation of the intellectual and perceptive activity in schizophrenic children aged 5 to 13 years (n = 102) as compared to healthy age-matched controls (n = 150) was carried out. Two complexes of techniques were employed, aimed at investigation of two interrelated aspects (operational and selective) of intellectual and perceptive (visual perception) activity. Dissociation of these components of cognitive activity observed in schizophrenic children already during the formation of perception gets more pronounced in the formation of thought. Dissociation of the development of the intellectual and perceptive activity of schizophrenic children may be considered as a component of abnormal mental development.
