- Abstract
This paper presents the monotony state investigation of the human-operator while simulator driving by using a combination of psychophysiological testing, registration of an electrocardiogram and electroencephalogram (EEG). The appearance of specific EEG-pattern (power ascension of the theta-, alpha- and beta-rhythms) during operator activity due to the monotony state progression was revealed. We found out the reduction in health, decrease activity, the increase of the situational anxiety, and the reaction time after 90 minutes of the monotonous activity. The signs of drowsiness were detected at the rest with closed eyes after operator activity. Moreover, these negative manifestations of the monotony state were observed mainly in subjects with domination of the alpha-activity in the left hemisphere.
