DYSONTOGENESIS OF THE MENTAL DEVELOPMENT OF PRIMARY SCHOOL-AGE CHILDREN FROM THE PERSPECTIVE OF THE PSYCHOLOGY OF TIME

Purpose: The article suggests an objective method of a chronometric test with the goal of differentiating the level of mental development of primary school-age children with early childhood autism syndrome and decreased intelligence organic genesis. Research Methods: Experimental Method timing using an electronic chronoscope which allows to determine the value of its own unit of time and accuracy in reproduction of time by ear by a person; methods of mathematical statistics: descriptive statistics, percentile statistics, methods of means values, comparison of average values ​​by Student's t-test, relative error of playback duration; testing method of J. Guildford adapted for children 5-15 years old. Results. Children with syndrome of early childhood autism and impaired intelligence have consistency between mental levels development and the ability to reproduce the proposed time intervals on hearing using an electronic chronoscope. In the case of early childhood autism syndrome, its own unit of time the individual is stable and it does not change in the reproduction of various time intervals. With a decrease in intelligence, it changes spasmodically, in depending on the depth of mental defect. Therefore it becomes possible substantiation of the cause of difficulties in this category of children with assimilation of temporary concepts, the formation of ideas about metric properties of time. Also, disorientation in past and future time in children with a slight degree of decrease in intelligence can be explained by a deviation from the analogue “Quality” clock, that is, high-quality functioning of the brain of the child.
