This experiment replicated many aspects of a UAV simulation paradigm in which imperfect automation aids assisted an easy visual monitoring task, while pilots concurrently performed a difficult surveillance task for targets of opportunity, and a primary mission completion task. In that study, changes in the threshold of the automated alert affected both the automated task and the concurrent task in a way suggesting that false-alarm prone automation is more disruptive of both tasks, than is miss-prone automation. In the current study, automation was applied to the difficult surveillance task, and task priority was manipulated. The current results still revealed a greater cost of false-alarm prone automation, again affecting both the automated and concurrent task. Priority instruction tended to produce better performance on the favored task. However with false-alarm prone automation, favoring this task actually reduced its performance. The results are interpreted in terms of the dichotomy between reliance, fostered by miss free automation, and compliance, fostered by false-alarm free automation. These two constructs were found to be only partially independent of each other.
