KOLESNYK A. Features of psychophysiological functions of children 5-7 years old with different individual typological properties of the nervous system.

The purpose of this work was to find out the features of psychophysiological functions of children 5-7 years old with different individual typological properties of the nervous system. To achieve the goal, the following tasks were solved: 1. To carry out a theoretical analysis of the scientific literature is devoted to the problem of the formation of psychophysiological, individual-typological properties of the nervous system in ontogenesis, their connection with mental attitudes of various types and degrees of complexity. 2. To establish the regularities of age dynamics of neurodynamic and sensorimotor functions of children of preschool and primary school age. 3. To investigate the peculiarities of the formation and development of memory and attention of children aged 5-7 years depending on the level of individual typological properties of the nervous system and their relationship with psychophysiological functions. 4. To identify the characteristics of the regulatory mechanisms of the autonomic nervous system of children with different individual typological properties. 5. To substantiate the possible functional interaction of the mechanisms of the central nervous system and the autonomic nervous system with the properties of attention and memory of children 5-7 years old. 6. To analyze the educational success of children of preschool and primary school age depending on their individual typological properties of HNA. The object of research – the formation and development of psychophysiological functions of children of preschool and primary school age. The subject of the research - the features of neurodynamic and psychomotor functions of children 5-7 years old with different individual typological properties of the nervous system and their vegetative support in the conditions of mental activity. Research methods: theoretical – analysis of scientific sources of information devoted to various aspects of psychophysiological development of children 5-7 years old, namely: individual typological properties of the nervous system, autonomic regulation of heart rhythm, attention, formation of visual and auditory memory; medical and biological methods - study of speed and qualitative characteristics of sensorimotor response of simple and complex selection reactions (SVMR, RC1-3, RC2-3) and indicators of neurodynamic functions (FMNP, SNP, BNP), psychophysiological development of children (visual, auditory memory and attention properties), statistical and spectral characteristics of heart rate variability; statistical - checking the results of the study for the presence of artifacts according to the Dixon criterion with their subsequent removal from the sample. For the normality of the distribution, the data were checked using the Shapiro-Wilk test. Since, the vast majority of the data obtained did not fall under the law of normal distribution, the Wilcoxon test was used for even comparisons, and the Mann-Whitney test with continuity correction was used for odd comparisons. The significance of the differences was considered significant at p < 0.05 or less. To establish the existence of a relationship between the variables, we used Spearman's rank correlation coefficient. The calculations and their graphical representation the results of the study were carried out in the programs "Statistiсa 64 V.12" and "Microsoft Excel 2010". The scientific novelty of the obtained results lies in the fact that for the first time the theoretically substantiated position throughout role of individual typological properties, neurodynamic properties in the formation of psychophysiological functions of children of preschool and primary school age.
