It is known that childhood is the period of greatest sensitivity to a various of adverse factors. One such factor may be the high level of personal anxiety of the child. Therefore, especially actuality obtained to the study of the functional state of children depending on anxiety as a stable individual characteristics. The aim of our research was to determine the psychophysiological characteristics of visual-motor reaction by children-northerners 8-11 years old with high anxiety.
In cross-sectional study involved 275 children 8-11 years old with a normal (171 persons) and high (104 persons) level of anxiety. Children studying in primary schools in Arkhangelsk and the Arkhangelsk region. All children were assessed indicators of simple and complex visual-motor reactions with the help of computer methods of registration time and errors of visual-motor reaction.
The results obtained in our study allow to judge about the adverse effect of high anxiety for visually-motor activity of the children. Indicators of the overall time both simple and complex visual-motor responses in the anxiety
children more than in children with a normal level of anxiety. However, statistical analysis of the results of the study have shown that the deterioration of the overall speed of reaction on the visual stimulus, of anxious children 8-9 and 10-11 years old is due to increased duration of different components of the response. The increase in the overall time of visual-motor reaction by children 8-9 years old with high anxiety occurs mainly due to the longer duration of the component motor reactions. The increase in the overall time of visual-motor reaction, of anxious children of 10-11 years old is due to the lengthening of the latent component of the response. As a result of studies it is established also, that children with high anxiety as compared to their peers with normal anxiety concede a greater number of errors in the performance of complex visual-motor tests, that indicates a decrease in the concentration of attention and the violation of the level of regulation and control over the flow of visual-motor reaction.
Thus, high anxiety leads to a deterioration of quantitative and qualitative indicators of visual-motor reaction of children northerners, therewith its influence on visual-motor reaction of children of 8-9 and 10-11 years old, expressed differently, because of the age dynamics of development of the components of sensomotor reaction.
