先进自动化系统的数量和复杂性的增加引起了人们对自动化引起的自满情绪的新关注，或者操作员难以监控自动化系统的状态。本研究包括两项研究，评估了系统可靠性、监控复杂性、操作员信任和系统经验对自动化引起的自满的影响。在这两项研究中，参与者操作手动控制的飞行任务，同时监控几个模拟飞机的故障显示。操作员在三个实验过程中检测单个自动化故障的能力也进行了评估。结果表明，实际的系统可靠性水平严重损害了作业者有效监控的能力。此外，随着系统经验的增加，作业者的监控性能下降。结果还表明，监测任务的复杂性严重影响操作员的监测，较差的表现与认知要求较高的任务相关。最后，两项研究的结果都表明，随着系统可靠性的提高，操作员信任增加，监控性能下降。这些结果表明，对于高度可靠的系统，不断增加的任务复杂性和丰富的经验可能会严重损害操作人员监控意外系统状态的能力。
The increase in quantity and complexity of advanced automated systems has generated new concerns surrounding automation-induced complacency, or the difficulties operators have monitoring the status of automated systems. The present investigation consists of two studies that assessed the impact of system reliability, monitoring complexity, operator trust, and system experience on automation-induced complacency. In both studies, participants operated a manually controlled flight task while monitoring several simulated aircraft displays for failures. The ability of operators to detect a single automation failure over three experimental sessions was also assessed. Results indicated that realistic levels of system reliability severely impaired an operator's ability to monitor effectively. Further, as system experience increased, operator monitoring performance declined. The results also indicated that the complexity of the monitoring task heavily influenced operator monitoring, with poorer performance associated with more cognitively demanding tasks. Finally, results from both studies indicated that operator trust increased and monitoring performance decreased as a function of increasing system reliability. These results suggest that for highly reliable systems, increasing task complexity and extensive experience may severely impair an operator's ability to monitor for unanticipated system states.
