title: [THe characteristics of the autonomic reactions of healthy adolescents and of those with lowered intellectual productivity].
abstract: Present research is devoted to psychophysiological study of the mechanisms of functional state control in normal and educationally disabled children using EEG, neuropsychological, and heart rate data obtained during different types of mental activity, including performance of arithmetic, verbal, spatial, and time-perception tests. Attention index and one-minute time interval production in the group of educationally disabled patients were found to be statistically lower than in the normal children. Heart rate level in this group was also lower than in the normal children of the same age. Increase of heart rate indices during perception of instruction and transition to its realization was statistically higher in the group of normal children. The differences between the groups can be explained by disfunction of the functional state regulation mechanisms, deficit of sympathetic influence and prevalence of parasympathetic ones, as well as by the weakness of the functions of the nervous system which causes disadaptation in educationally disabled children.
