[Neuropsychological study of memory in the complex clinical, psychological and neurophysiologic examination of children with schizophrenia].

Combined clinical, psychologic and neurophysiological investigation was conducted in children with slow-progredient schizophrenia: with dominant affective disorders and hypomaniac states (Group I, 14 patients), and with predominant neurosis-like and psychopathy-like pathology (Group II, 12 patients). The patients distinctly differed in not only the clinical course of the disease but also according to neuropsychological investigations of memory, pathopsychological and EEG studies. These data are reliably intercorrelated.

[Clinico-psychological examination of children with protracted hypomanic conditions in schizophrenia].

A clinico-psychological study covered 28 children aged 4-13 years with protracted hypomanic states (2-8 years) in 3-10-year-long schizophrenia. The authors investigated peculiarities of the development of cognitive activity (thought and perception). Comparison was made between groups of schizophrenics and control groups (the syndrome of motor disinhibition, schizoid psychopathy).

[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.

[Characteristics of the formation of anomalous thinking in children with schizophrenia].

The traits of age thinking development (formation) were studied by experimental and psychological tests in children aged from 5 to 14 years who were diagnosed as suffering from favorably developing forms of schizophrenia. During all the age periods this group of children showed a deviation in the thinking development, compared to that of the control normal group. The tests detected an abnormal form of thinking not described before which was characterized by typical changes in the interrelationship and dynamics of 2 significant sides of thinking activity.

[Features of thought formation in schizophrenic children].

The paper deals with problems related to the onthogenetic formation of a special type of the pathological cognitive activity. Such activity was expressed in disturbances of selective actualization of knowledge based on the past experience. Experimental psychological studies were performed in children from 5--14 years of age, with slowly progressive forms of schizophrenia.
