本研究考察了任务优先级如何影响操作员对不完美自动化的扫描模式和信任评级。先前的研究表明,当主要任务需要更多的注意力时,参与者对辅助不完美自动化的次要任务的视觉显示器表现出较低的信任和固定频率较低。这一现象的一个解释是,增加的主要任务的需求导致参与者优先考虑的主要任务比次要任务。本研究要求参与者使用多属性任务组合(MATB)II同时执行跟踪任务、系统监控任务和资源管理任务。自动化辅助系统监控任务,可靠性达70%。通过跟踪任务的难度来操纵任务负荷。明确指示参与者将跟踪任务优先于所有其他任务(跟踪优先级条件)或降低跟踪性能(同等优先级条件)。结果表明,任务负荷对注意分配,任务绩效和信任评级的影响。此外,在同等优先级条件下,参与者报告较低的性能为基础的信任时,跟踪任务需要更频繁的手动输入(跟踪条件),而没有任务负载的影响下,跟踪优先级条件下观察。在动态多任务环境中,任务优先级可以通过消除任务负载对自动化信任的不利影响来调节自动化信任。
The present study examined how task priority influences operators’ scanning patterns and trust ratings toward imperfect automation. Previous research demonstrated that participants display lower trust and fixate less frequently toward a visual display for the secondary task assisted with imperfect automation when the primary task demanded more attention. One account for this phenomenon is that the increased primary task demand induced the participants to prioritize the primary task than the secondary task. The present study asked participants to perform a tracking task, system monitoring task, and resource management task simultaneously using the Multi-Attribute Task Battery (MATB) II. Automation assisted the system monitoring task with 70% reliability. Task load was manipulated via difficulty of the tracking task. Participants were explicitly instructed to either prioritize the tracking task over all other tasks (tracking priority condition) or reduce tracking performance (equal priority condition). The results demonstrate the effects of task load on attention distribution, task performance and trust ratings. Furthermore, participants under the equal priority condition reported lower performance-based trust when the tracking task required more frequent manual input (tracking condition), while no effect of task load was observed under the tracking priority condition. Task priority can modulate automation trust by eliminating the adverse effect of task load in a dynamic multitasking environment.
