Abstract This study investigated the behavioural and psychophysiological changes during a simulated process control task performed under single and combined physical stressors. Twenty-four subjects took part in the task on a visual display unit (VDU), in 4 experimental conditions: adequate lighting (control); noise; inadequate lighting; noise and inadequate lighting. Response times (performance), electroencephalogrammes, electro-oculogrammes and heart rate (vigilance indicators) were continuously recorded during the task. The main results show that the longest response times and the highest activation levels occurred in a multistressor environment. This suggests that combined inadequate lighting and noise impairs the operator's efficiency in process control on a VDU. Recommendations are made for improving the situation in such workplaces.
