The study of psycho-physiological characteristics of elderly teachers is of great importance. The article aims to study functional indicators of the central nervous system and cognitive performance of elderly teachers. The sample included 21 women at an average age of 56.2). The integral characteristics of the central nervous system activity were diagnosed using Biomysh-Research (LLC Neyrolab, Moscow). Chronoreflexometric tests (simple visual-motor reaction and complex visual-motor reaction) estimated the speed of neuronal sensory information processing, mobility of nervous processes, stability of human sensomotor reactions. The functional state of the central nervous system was diagnosed using the Loskutova's criteria (the functional level of the system, reaction stability, the functionality level). The results were processed in Microsoft Excel and Statistica v.7.0. An optimal functional state of the central nervous system is characteristic of the group of teachers aged 56.2. Processing performance of complex sensorimotor information and duration of differentiating inhibition reflect the reduced cognitive performance in most of the teachers.

The purpose of the study is to establish the effect of different levels of physical activity on the psychophysiological characteristics of teenagers, serving as the basis for the design of a health-saving educational development path. In the course of the study, 175 teenagers (12-14 years old), including 63 girls and 112 boys (34 boys playing hockey), were examined. For all subjects, we evaluated the indicators capturing a simple and complex visual-motor reaction using the BioMouse-Research hardware-software complex. The obtained results characterize the optimal level of cerebral homeostasis, reflected in the average sensorimotor response of all examination groups falling within the age norm range. The authors argue that the developed motor skills of teenagers involved in sports contribute to a greater cerebral speed of processing elementary sensory information, as well as high activity and mobility of the nervous processes of the central nervous system in comparison to peers not involved in sports.

Ethnic diversity describes the plurality of ethnicities within a group of people coexisting in one territory. The permanent presence of other cultures’ representatives can trigger a sense of jeopardy; a feeling that the prevailing way of life, its norms, and its values are challenged by strangers, which results in hostility to ethnic minorities living in the same territory. In this context, the study aimed at investigating specific features of the individual’s ethnic identity determined by the degree of the ethnic diversity of their living environment is of relevance. In order to define regions for the study, the comparative analysis of the ethnic diversity of Russian regions was conducted. Two regions for the study were defined: the Sverdlovsk region as a territory with average ethnic diversity and the Republic of Bashkortostan as a highly diverse region in terms of ethnicity. The respondents from less ethno-diverse areas exhibit global self-identification, the awareness of being a part of the world, and territorial identity. Differences in the degree of sustainability and the intensity of ethnic self-identification of the subjects from regions with varying degrees of ethnic diversity were revealed. Significant distinctions in the meaning of ethnicity for the compared groups of the respondents were found.
