A driving simulator was used to examine the effects on driving performance of auditory cues in an in-vehicle information search task. Drivers' distraction by the search tasks was measured on a peripheral detection task. The difficulty of the search task was systematically varied to test the distraction caused by a quantified visual load. 58 participants completed the task. Performance on both search tasks and peripheral detection tasks was measured by mean response time and percent error. Analyses indicated that in-vehicle information search performance can be severely degraded when a target is located within a group of diverse distractors. Inclusion of an auditory cue in the visual search increased the mean response time as a result of a change in modality from auditory to visual. Inclusion of such an auditory cue seemed to influence distraction as measured by performance on the peripheral detection task; accuracy was lower when auditory cues were provided, and responses were slower when no auditory cues were provided. Distraction by the auditory cue varied according to the difficulty of the search task.
使用驾驶模拟器研究了在车内信息搜索任务中听觉提示对驾驶性能的影响。通过外围检测任务来衡量搜索任务对驾驶员的干扰程度。系统地改变搜索任务的难度，以测试量化视觉负荷引起的干扰。58 名参与者完成了任务。通过平均响应时间和百分比误差来衡量搜索任务和外围检测任务的性能。分析表明，当目标位于一组不同的干扰物中时，车内信息搜索性能可能会严重降低。在视觉搜索中包含听觉提示会由于从听觉到视觉的模式改变而导致平均响应时间增加。提供这种听觉提示似乎会影响外围检测任务的表现，从而影响干扰程度；当提供听觉提示时，准确性较低，当不提供听觉提示时，响应速度较慢。听觉提示的干扰程度根据搜索任务的难度而变化。
