DYNAMICS OF HUMAN COGNITIVE FUNCTIONS WHILE SOLVING SOPHISTICATED DYNAMIC CASES IN THE CONDITION OF 21-DAY BED REST

The paper deals with the study of psychophysiological tolerance of uncertainty in the process of solving sophisticated dynamics cases in conditions of periodic cognitive testing in the course of 21-day bed rest (BR, -6°). The study was performed at IBMP in two stages, i.e. in October-September, 2021 and October-December, 2022. Psychophysiological and cognitive data were collected 7 days prior to BR (baseline), on BR days 3, 10, 17 and 21 on stage-1 and on BR days 4, 10, 16 and 21 on stage-2, and in 3 days after BR completion. Cognitive dynamics was analyzed using the sophisticated dynamic cases with elements of uncertainty (SW CleverBalls, Russia). Tolerance of preset uncertainty as a sum-total of success scores grew more than 50 % in BR stage-1. In BR stage-2, analysis showed both a 39 % improvement and 38 % degradation of the group total-score. This disagreement between the results calls for further investigation. Testing the aptitude to solve professional tasks with various levels of uncertainty may instigate development of countermeasures adaptable to individual psychophysiological demands and reactions.
