PSYCHOPHYSIOLOGICAL PREDICTORS OF THE INTERNAL PICTURE OF PRESCHOOL CHILDREN'S HEALTH

Currently, there are contradictory data on the role of certain psychophysiological mechanisms in the formation of the internal picture of the health (IPH) of older preschool children. Moreover, there is no single idea about the possibilities of screening diagnosis of the level of IPH in children. That is why the purpose of our study was to identify, on the one hand, the relationship between the features of the internal health picture and the parameters of heart rate variability, as well as with the features of children's executive functions, and, on the other, to explore the possibilities of using the “Express diagnosis of a child” technique as a method of screening diagnosis of the features of older preschoolers. The study involved 100 children of senior preschool age. The special features of the IPH were identified using the following methods: “Express diagnosis of a child”, a modified questionnaire “Attitude to health”, a modified questionnaire “Well-being, activity, mood”, the method “Health and illness”. The study of psychophysiological predictors of IPH included the study of the features of working memory using the Interference technique, and the features of heart rate variability using the OMEGA-M software and hardware complex. According to the results of the study, it was found that the data on the Express diagnosis of a child method are related to the level of children's IPH. It was revealed that preschoolers have a high level of the emotional component, an average and high level of the cognitive component, a high level of the value-motivational and behavioral components of the higher education system. In the structure of the internal picture of health, two factors can be distinguished, each of which reveals in its own way the features of preschool children's health conditions. It was found that children with a low level of internal health picture show the highest rates of memory interference. The interrelation of the internal picture of health, interference of working memory and features of variability of children's heart rate is shown. In the situation of a conversation about health, it was revealed that the better the child understands what health is, the lower the centralization of cardiac rhythm management, and the higher the influence of the parasympathetic division of the autonomic nervous system on cardiac rhythm.
