| Abstract |
2h of simulated driving was employed to study the combined effects of noise and vibration on performance and physiological arousal. Overall performance did not change significantly with experimental conditions, whereas the cerebral and autonomic arousal levels increased with noise and vibration, alone or in combination; performance deteriorated over time, and the arousal level decreased from the beginning to the end of the sessions. Since the same overall performance is observed at a higher arousal level during combined exposure to noise and vibration, there is a compensatory attentional effort for coping with the task under stress. The decrements in performance and physiological arousal over time indicate that this compensatory effort cannot be maintained throughout a long driving task under environmental stress. |
