Abstract
The article considers the influence of sensory (visual and auditory) deprivation on a sensorimotor response, memory, and attention among 8-11 years old children. The literature review concludes that sensory deprivation causes discomfort and problems in perceiving of reality. Also, under the influence of various factors that damage body structures, compensatory reactions are launched to compensate for impaired functions. The processes that provide the body with the restoration of lost structures and impaired functions of the pathology are called «compensatory-adaptive processes». Having conducted statistical analysis of the obtained data of latent periods of different sensomotor responses among children with sensory deprivation and the control group, it is seen, that the level of stimuli in the form of figures was higher among children with hearing impairments, and in the form of sounds – in the group of children with visual impairments. According to the results of our study, we can assume that in groups of children with sensory deprivation the process of compensating the impaired function of a particular analyzer takes place at the expense of another one.

Having conducted the statistical analysis of the obtained data of latent periods of different sensomotor responses among children with sensory deprivation and the control group, it is seen, that the level of stimuli in the form of figures was higher among children with hearing impairments, and in the form of sounds – in the group of children with visual impairments
It has been revealed that the latent period of simple visual-motor reactions of children with auditory sensory deprivation to figure statistically almost does not differ from similar indicators of the control group children
Summary
In Ukraine, the health of children and young people cannot be considered satisfactory. Among the negative factors, affecting the health of preschool and school-age children, are hearing and visual impairment, infections, traumas, and overuse of modern electronic devices. Children with hearing and visual impairments take a significant place among children with disturbances of development. According to the world statistics, in progressive countries, every twentieth preschool child and every fourth schoolchild has visual impairments. The most common childhood diseases are myopia, hyperopia, and astigmatism. As for hearing, according to the statistics, in Ukraine, there are more half a million children with hearing impairments. More than 6 % of the population has severe hearing impairments, so the problem of deafness and hearing loss is as important as vision problems [1]
