СТАН ФУНКЦІОНАЛЬНОЇ РУХЛИВОСТІ НЕРВОВИХ ПРОЦЕСІВ В УМОВАХ СЛУХОВОЇ ДЕПРИВАЦІЇ

Abstract

The article discusses the effect of sensory deprivation on the state of functionalmobility of nervous processes in schoolchildren aged 15-16. The relevance of the studyis the need to obtain and analyze new scientific data on the specificity of the impact ofauditory deprivation on the functional mobility of the nervous processes (FMNP) of a person. The main objective of this phase of the study was to study the features of thefunctional mobility of the nervous processes in children with hearing impairments.The studies were conducted, taking into account changes in the fluctuations ofmental performance during the working day and week, all studies were conducted ondays of high mental performance - from Tuesday to Thursday from 9.00 to 13.00hours. The total amount of experimental research for each subject represented nomore than 10 minutes in one examination. At the beginning of the study, eachindividual was familiarized with the methodology for studying the functional mobilityof nerve processes using the feedback mode. The study for the entire contingent wascarried out using the computer diagnostic method "Diagnost-1M", which wasdeveloped in the laboratory of physiology of higher human nervous activity of theInstitute of Physiology named after. O.O. Bogomoltsa National Academy of Sciencesof Ukraine (Kiev) professors M. V. Makarenk and V. S. Lizogub.After analyzing the data, we found that the mean values of FMNP in childrenwith sensory deprivation were statistically different from those in the control group.The reason for this is mental retardation and hearing problems in children withimpaired hearing. Qualitative analysis showed that among students in the controlgroup, individuals with high and medium levels of functional mobility of nerveprocesses are more often observed, and in the experimental group - children with lowlevels of FMNP. The central processing time is the shortest for the students in thecontrol group, in contrast to the experimental one. This is due to the lagging behind ofhearing impaired people in the area of forming perception of objective actions as aresult of speech underdevelopment. Also, the average values of the right-handedFMNP are significantly better compared to the functional mobility of the left hand inboth groups. This is due to the dominance of the right hand as a powerful means ofadaptive human behavior.Keywords: functional mobility, sensory deprivation, informationprocessing.
