OBJECTIVE Two experiments were conducted in which participants navigated a simulated unmanned aerial vehicle (UAV) through a series of mission legs while searching for targets and monitoring system parameters. The goal of the study was to highlight the qualitatively different effects of automation false alarms and misses as they relate to operator compliance and reliance, respectively. BACKGR...

Twenty-four participants flew a simulated unmanned aerial vehicle (UAV) through ten mission legs while searching for targets of opportunity and monitoring system parameters. Participants were assisted by automation which provided auditory alerts in response to system failures (SF). The auto-alerts were either 80% reliable or 60% reliable; the latter condition resulted in either a 3:1 ratio of f...

Thirty-two undergraduate pilots from the University of Illinois School of Aviation performed simulated military reconnaissance missions with an unmanned aerial vehicle (UAV). Pilots were required to: a) navigate the UAV through a series of mission legs, b) search for possible targets of opportunity, and c) monitor system health. They performed the missions under three types of auditory auto-ale...

Forty-two participants manipulated two or four unmanned aerial vehicles (UAVs) while monitoring an adjacent display for camouflaged tanks. They were sometimes supported in the tank-detection task by an automated target recognition system that operated at either a reliability of .9 with a threshold designed to provide an equal number of false-alarms and misses, .6 with a low threshold producing ...

Nestling begging in the absence of parents may reflect ‘‘false alarms’’ due to cognitive constraints or signaling activity toward nest mates (sibling negotiation). According to signal detection theory, cognitive constraints should result in both false alarms (begging in the absence of parents or to inappropriate stimuli) and misses (failure to beg during parental visits). In our study of house ...

Does incremental reinforcement learning influence recognition memory judgments? We examined this question by subtly altering the relative validity or availability of feedback in order to differentially reinforce old or new recognition judgments. Experiment 1 probabilistically and incorrectly indicated that either misses or false alarms were correct in the context of feedback that was otherwise ...

The author examined the effects of human responses to automation alerts and nonalerts. Previous research has shown that automation false alarms and misses have differential effects on human trust (i.e., automation false alarms tend to affect operator compliance, whereas automation misses tend to affect operator reliance). Participants performed a simulated combat task, whereby they examined aer...
