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 article is devoted to the current problem of Internet addiction of young people in the context of digitalization of modern education and the practical implementation of interactive learning technologies. The authors pay attention to the definitions of such concepts as virtual educational environment, virtual learning process, interactive learning. The article analyzes the manifestations and consequences of Internet addiction among modern youth. The authors emphasize that the psychophysiological mechanisms that can affect the development of Internet-dependent behavior are insufficiently studied. One of these mechanisms can be the inhibitory control, which, according to the authors of the article, is able to signal the presence of a danger of the formation of the Internet addiction.The article presents the results of an experimental study aimed at studying young men and women’s computer and Internet addiction with the help of “The method of screening diagnostics of computer dependence” (Yuryeva L.N., Bolbot T.Yu.) and the “Internet addiction” test by K. Young (adaptation by V.A. Loskutova). It was found that most of the subjects have a high level of dependence. Also, the assessment of the formation of the inhibitory control was carried out using the ReBOS technique, reflex metric measurements (by E. G. Vergunov). The authors concluded that young men and women with a higher degree of dependence demonstrate a low level of formation of the inhibitory control, subjects who have a lower degree of dependence both on a computer and on the Internet have a more flexible nervous system, which is indicated by the higher level of the inhibitory control formation. Thus, it can be assumed that students who are less dependent on the Internet will be able to adapt more easily to a fast-changing environment.
The article discusses the relations of the sensorimotor integration and inhibitory processes with the features of the internal position of the patient’s personality. Sensorimotor integration is considered as a characteristic of the mental processes, allowing us to estimate the peculiarities of the flexible rearrangements in the brain in the course of the formation of the new connections. Inhibitory control is considered as a psychophysiological characteristic responsible for cognitive inhibition and suppression of a certain type of behavior. The respondents were voluntary participants (a total of 98 people, 60 women and 38 men) with different levels of health, namely: (1) chronically ill (health group 3) - the total number of 50 people (average age 37 ± 11.1 years); (2) healthy people with certain functional abnormalities - 48 people (average age 34 ± 10.6 years). The types of attitudes to the disease were measured with the TOBOL inventory by L. Vasserman et al. The ReBOS technique by E. Vergunov was used to diagnose the orderliness of the sensory flow and the inhibitory processes level. It is shown that the representatives of the second and third health groups are diagnosed with an identical set of types of attitude to the disease, which is not constructive. That allowed us to divide them into groups according to the degree of adaptation. The respondents, whose mental and social adaptation is not impaired, are more difficult to adapt to the changing conditions, they have recorded rigidity and insufficient development of the inhibitory processes, they are capable of purposefully following the chosen model of behavior, but the underdevelopment of the inhibitory processes does not allow them to stop the implementation of the non-constructive attitude to health. In the respondents, whose type of response to the disease is characterized by the presence of mental maladaptation, the nervous system is more flexible and the inhibitory processes are better developed, they are able to purposefully follow the selected attitude to the disease, and are able to “slow down” the implementation of the chosen strategy. At the same time, the respondents are focused on their own condition, which prevents them from exercising conscious inhibitory control. The results suggest that the perception of the sensory flow and the level of inhibitory processes are related to the internal position of the individual, but the nature of the connections is determined by the degree of the constructive attitude to the disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
