Abstract

Psychophysiological abilities of a group of operators working at a control panel in a power station were tested with a battery of tests. The battery included biochemical tests (adrenaline, noradrenaline and 17-0HCS), physiological test (arterial blood pressure), visual tests (accommodation, convergence, phoria and dark adaptation), psychological tests (visual and auditive reaction time) and subjective estimation of fatigue. Workers from three different work shifts, with a constant change of the shift system every two clays, were tested before and after work (at 6 a. m. and at 2 and 10 p. m.). Characteristic changes were found after work in all the three shifts, but the changes were significant only after work in the night shift. A significant change in adaptation to dark was also noticed after work in the afternoon shift. A lack of sleep and night work increased arterial blood pressure, and prolonged the period of adaption to dark. They also increased variability of auditive time reaction and the feeling of fatigue. The accommodation rate was decreased.
