title: [Individual propensity to active or passive behavior during exposure to emotional stress in individuals with various blood cortisol levels].
abstract: Effects of baseline and reactive blood cortisol on operator's performance were studied in subjects with active of passive behavioral reactions under exposure to stress. The type of behavioral reaction to stress (shift in the rates of omissions or false alarms) was found to be associated with the baseline blood cortisol and its levels averaged in the course of the experiment. Subjects with active reaction (stress produces an increase in the rate of errors of the false-alarm type) were characterized by the low cortisol level, whereas its high level was observed in subjects with passive reaction (stress produces an increase in the rate of errors of the omission type). Individuals with high baseline cortisol level and those with the passive reaction to stress exhibited enhanced cardiovascular reactivity during performance in normal conditions and its reduction during the performance under exposure to stress.
