Physiological characteristics of regulation of emotional responses among specialists of extreme profile

Abstract

The results of the examination psychophysiological mechanisms of coping with emotional reactions in stressful situations of the specialists of extreme profile are presented. The integrated biofeedback protocol using various functional tests has been developed. Statistical clustering method k-means was used; validation of the differences between the resulting clusters was carried out using one-way ANOVA. The internal consistency of various indicators of the autonomic and central nervous systems was revealed by the pairwise Pearson's correlation coefficient. Target variables for the mathematical analysis were: relative powers of alpha, theta, beta 1 and beta 2 rhythms, HR, HF, LF, VLF, RR, VS, LF/HF, TP, IC, SNCA, ASV, GSR. Multiple relationships between different levels of regulation of emotional state, the flexible use of different coping strategies, the ability to create new mechanisms of regulation in accordance with the objective and high braking performance the emotional state after the termination of the stressors was detected in the group with high stress sustainability. The group with low stress sustainability has been described by the opposite pattern.
