Optical coordination functions in hearing impaired children of primary school age

Relevance. he relevance of this study is due to the scientific need for an in-depth study of the mechanisms of the relationship between visual perception and coordination functions in conditions of auditory deprivation, as well as the practical need to obtain data that will form the basis for the development of targeted correctional and developmental programs.

Purpose. The aim of the study is to study the relationship between visual perception and coordination functions in hearing–impaired children of primary school age. The central hypothesis of our study is the assumption that the relationship between visual perception and coordination functions in hearing-impaired children of primary school age differs from the relationship in normotypic children of the same age.

Materials and Methods. Theoretical research methods: bibliometric analysis, conceptual and categorical analysis. Empirical research methods: analysis of medical documentation, observation, clinical conversation, superimposed images (black and color), "Missing parts" subtest, Raven matrices, "Find out who it is" technique, Tandem test, Uemura test, "March-cotton" test, Head test, "Folding pictures" subtest", the "Labyrinths" subtest, the Ozeretsky and Gurevich test, the right-left orientation test, the Taylor test.

Results: During the correlation analysis of visual perception and coordination functions in hearing-impaired children of primary school age, 6 significant relationships were identified. 4 correlations have a neg ative trend and 2 correlations have a positive trend. 9 significant relationships were identified in normotypic primary school children. A large number of correlations may indicate a diverse relationship between visual perception and coordination functions in normotypic primary school children. 8 correlations have a negative trend and 1 correlation has a positive trend.

Conclusions: As a result of the study of the relationship between visual perception and coordination functions in hearing-impaired primary school children and their normotypic peers, we have obtained data that confirm the central hypothesis of our study that the relationship between visual perception and coordination functions in hearing-impaired primary school children differs from the relationship in normotypic children of the same age.
