Introduction. Analysis of the literature suggests that the particular nature of the interplay between a person's creativity and intelligence is determined not only by the conditions in which a person develops and their personality traits, but also their age. Objective. The purpose of this study was to compare the interaction between the levels of creativity and intelligence of 7 to 8 year-old children and 12 to 13 yearold teenagers, by studying how 7-8 year-old children and young teenagers (12-13 years old) with different levels of intelligence and creativity assimilate stochastic signals. Design. A total of 160 children took part in the study, 80 first-and secondgraders who were 7-8 years old (37 boys and 43 girls), and 80 fifth-graders, aged 12-13 (40 boys and 40 girls). We used the following procedures: Raven's Progressive Matrices; a battery of creative thinking tests, amounting to a modification of the Guilford and Torrance's tests in a Russian adaptation created by E. Tunik; and the computer reflexometric method. Results. Our findings showed that the relationship between the level of intelligence and the level of creativity is different in the two age groups. With 7-8 year-olds, the two parameters are independent of each other, whereas with 12-13 year-olds, there is a weak but significant link between them. With the 7-8 year-old children, the level of creativity predetermines the child's ability to detect the structure of a sensory stream that is organized in a complex way. At the ages of 12-13, neither the level of creativity nor the level of intelligence is correlated with the parameters of sensorimotor integration, but the two parameters are interconnected.

Background. An inner health picture (IPH) includes a person's image of him-or herself as healthy, and knowledge of the methods needed to achieve the behavior necessary to maintain his (her) health. The IPH of a preschooler is formed by his (her) parents, and the high level of physical activity which is needed for supporting his (her) IPH could change a child's capacity to orient in sensory flow.Objectives. The objectives of this study were twofold: 1) to compare the children's IPH with that of their parents, and 2) to study the connection between a child's IPH with his (her) capacity to recognize consistent patterns in the structure of a stream of sensory signals.Design. 82 primary school children and their mothers participated in the study. The study was conducted in two stages. During the first stage, the internal picture of health (IPH) of the children and their parents was evaluated by means of a questionnaire. To describe a child's ability to discern some kind of order in a stream of sensory signals, the models of simple and complex sensorimotor reactions were used.Results. Parents whose children have a well-developed IPH steer their children toward a healthy lifestyle, whereas they themselves do not do what is necessary to maintain their own health. The process of developing an IPH is accompanied by an increase in control during performance of a serial reaction task, which is reflected in a decrease in the number of lapses or missed stimuli. Conclusion. An IPH is an internal mental model that not only predetermines a child's notion of themselves as a healthy person; it also has a psychological basis in the form of a system that strengthens the child's control over his (her) own actions.

Background: We analyzed the hypothesis that the vestibular and auditory systems are integrative functions. Methods: The study involved 383 children (5.5 ± 2.4 years old). We assessed the conduct of auditory information by recording the auditory brain stem response (ABR), post-rotational nystagmus (PRN), and cervical vestibular evoked myogenic potentials (cVEMP), and calculated the integration of the parameters. All procedures were carried out using the JACOBI 4 software package. Results: We have found out that PRN, ABR, and cVEMP represent three different groups of integrative functions, each of which is conditioned by its own integrative mechanism. We have proven that PRN and ABR are associated with age, but no relationship was found between cVEMP and age. Conclusion: According to our data, the severity of ABR and PRN depended on age, while cVEMP was not associated with age. The functional immaturity of the child’s vestibular system, which probably arose in utero, often becomes apparent only at school when reading and writing must be mastered. These skills require maturity of both the vestibule ocular and vestibule spinal functions of the vestibular system.

The age dynamic of parasympathetic and sympathetic activity of autonomous nervous system (ANS) in the heart rate (HR) regulation is considered in the article from the perspective of allostasis theory. Two groups of people are compared: working residents of Arctic region (aged from 20 till 75 years old, divided in 10-years age cohorts, total 267 people) and working residents of the Central Part of Russia (116 people). The model of allostatic influence on the organism's regulatory systems in the process of adaptation to the conditions of high latitudes is studied compared to clustered data of HR analysis recorded in the background. The model of allostasis implies to support an organism's inner stability not from the perspective of body balance control but through changes preservation according to external conditions. «The adaptation cost» as a result of allostaric load is described by means of peculiarities of HR regulation in indifferent groups of surveyed. A method of human adaptation potential assessment by means of the analysis of ANS parasympathetic parts contribution to HR regulation is rested and discussed in the article. This approach allows to reveal risk group candidates for adaptation process breakdown.
