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.
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.
The purpose of the research was to compare different methods of handedness assessment. Participants included 161 children between 4 and 7 years of age: 87 girls and 74 boys. The research incorporated typical methods used in investigations and assessment of lateral phenotype. All tests were repeated at least three times to assess their reliability in assessing children. Our findings reveal that different sets of assessments and scoring methods produced different results in determination of right- or left-handedness. Factor analysis identified three significant factors of handedness: social pressure, genetic mechanisms, and two-hand coordination. We conclude that it is necessary for assessment of handedness to use at least three testsassociated with each of these factors.
Keywords: handedness, left-handedness, methods, lateral profile, children.
