Objective of the study was to study some indicators of sensorimotor systems in students aged 7-10 at the beginning of a one-year educational cycle in a special correctional I-II type and general education schools.
Methods and structure of the study. The survey involved 311 healthy schoolchildren aged 7-10 years and 96 peers suffering from sensorineural hearing loss (III-IV degree). The Neurosoft-NS-Psychotest complex was used. In children, a simple visual-motor reaction (VMR) was studied; reaction to a moving object. We analyzed the results obtained in the methods of "reaction time of discrimination" and "reaction time of choice".
Results and conclusions. As we grow older, the period of the sensorimotor reaction decreases, which is associated with the process of maturation of the central structures of the brain and the improvement of the functional state of the neuromuscular apparatus. In children 9-10 years old, the degree of balance between the processes of excitation and inhibition is greater in strength, which indicates the balance of nervous processes and the stability of the functioning of the nervous system at this age. With increasing age in children, the mobility of nervous processes is optimized. The functioning of sensorimotor systems in children 7-10 years old with auditory deprivation, in comparison with practically healthy peers, showed that the development of the mechanisms of central regulation of movements is somewhat slow.
