Abstract

Using a simulated UAV control task in which a vigilance display warned observers of the presence of enemy threats, Gunn et al. (2005) reported that perceived mental workload in relation to the vigilance task was unexpectedly low. The present study did not confirm that finding. It did show, however, that vigilance performance was greater and task induced stress was less among observers who had the opportunity to act upon vigilance signal detections by destroying the enemy threats than among those who detected threats but had no opportunity to counter them. Accordingly, the results point to the importance of a detection-action linkage to enhance signal detection and reduce stress in the performance of vigilance tasks.
