| 摘要： | Student pilots participated in a series of four experiments to examine conflict alerting systems to augment the cockpit display of traffic information in a dual task context. At issue was the nature of task management and task switching, and how this was influenced by the modality of the alert, the level of resolution of the alert (likelihood 3-stage vs. binary 2-stage), the threshold setting of the alert, and the nature of the concurrent task (tracking or a navigational computational task). Across all four experiments the binary alert was generally more effective than the likelihood alert, and the auditory alert generally supported better conflict detection response than did the visual alert. However the impact of modality on the concurrent task was modulated by the nature of that task (visual tracking was more disrupted by the auditory alert, than was visually mediated communications). Variation of alert threshold between experiments indicated that false alarm prone automation delayed response to the alert, whereas miss-prone automation degraded the concurrent task. The results are interpreted in the context of theories of task management and task switching and multiple resources, and of the reliance-compliance theory of automation dependence. / NOTE: Technical rept. / Supplementary Notes: Sponsored by National Aeronautics and Space Administration, Moffett Field, CA.
