STATE OF THE MAIN PSYCHOPHYSIOLOGICAL FUNCTIONS IN MILITARY SERVANTS OF DIFFERENT AGE GROUPS

To discover age-related changes in the simple sensorimotor reaction (SSMR), choice reaction (CR), functional mobility of nervous processes (FMNP) and brain productivity (BP), as well as to determine the stress index (SI) of regulatory systems during performance of these tests. Forty-seven healthy volunteers, representatives of military professions, aged 18–54 were divided into three groups (first group – 18–23 years, n=16; second group – 24– 34 years, n=19; third group – 35–54 years, n=12) and performed original computer tests to determine SSMR, CR, FMNP and BP. An electrocardiogram (ECG) was recorded in parallel. Although the rate of SSMR and CR did not differ for participants of three groups, the SI was significantly higher in the third group, compared with the first group (p
