Psychophysiological Characteristics of the Central Nervous System of Rural Children of Various Ethnic Groups of Siberia

Abstract

Aim: a comparative assessment of the psychophysiological parameters of the central nervous system in rural children of different ethnic groups. Methods. Rural children aged 11-17 participated in a one-stage observational survey (124 - Buryat and 132 - Slavic ethnic groups). A simple visual-motor reaction and a teping test were used to study the psychophysiological characteristics of the central nervous system. Results. The Buryat children had a high level of efficiency, endurance to the effects of dynamic loads, a strong type of central nervous system (63.4 ± 6.5) %. The children of the Slavs were characterized by a low level of efficiency and a weak type of the central nervous system (76.3 ± 5.9) %. The rate of movement in relation to the initial level has changed less in Buryat children than in Slavic children. Buryat children 11-14 years old compared with children of the Slavic ethnic group are more likely to have individuals with inertness of nervous processes (52.1 ± 7.2) % Buryat and (22.5 ± 6.6) % Slavs, p = 0.003. The dynamics of the sensorimotor response rate increases in children of both groups with age. Conclusions. Psychophysiological characteristics indicate that among rural children of the Buryat ethnic group, people with a high level of efficiency and endurance to dynamic loads, a strong type of central nervous system, are more likely than children of the Slavs. The level of the functional state of the central nervous system by the criteria of Loskutova TD in children of different ethnic groups is estimated as reduced.
