[Quality of operator's performance and associated physiological reactions in relation to stress-tolerance]

The purpose was to study operator's stress-resistance by correlating the results of work with its physiological effects associated with the sympathetic system reactions. Hard- and software Neurolab-200M was used to test 10 subjects in two experiments with different stressful conditions. Work efficiency was assessed by time for completion and accuracy of the "Manometers test" challenging the ability to perceive information and to take decision under severe time limitation. Heart rate per a minute, systolic and diastolic blood pressure were measured immediately before and during the test. According to the results of the experiments, two subjects demonstrated low stress-resistance when doing the operator's tests. Comparison of the physiological data of these and the rest subjects showed good agreement with the hypothesis that weak stress-resistance, unlike the strong one, is associated with less pronounced stress-induced sympathetic reactions.
