To investigate interference between the sustained and occasional attention required in driving, performance of 36 participants engaged in a focal manual tracking task and a peripheral detection task, representing sustained and occasional attention, respectively, was studied. Error ratio, tracking distance, tracking speed, and root mean squared tracking distance error were taken for manual tracking, and response times were measured on the detection task. Analysis indicated that multiple tasks or highly sustained attentional demands preceded lower performance on sustained attention tasks. Performance on occasional attention tasks after multiple tasks may also decrease, but occasional attention performance improved when the participants were engaged concurrently in a task involving higher sustained attention. Furthermore, the association between sustained and occasional attention was strengthened as the number of tasks or the demands of sustained attention increased.
为了研究驾驶过程中持续注意力和偶发注意力之间的干扰，研究了 36 名参与者在进行集中手动跟踪任务和周边检测任务时的表现，这两个任务分别代表持续注意力和偶发注意力。手动跟踪的指标包括错误率、跟踪距离、跟踪速度和均方根跟踪距离误差，而检测任务的指标则是反应时间。分析表明，多项任务或高度持续的注意力需求会导致后续持续注意力任务的表现下降。在完成多项任务后，偶发注意力任务的表现也可能下降，但当参与者同时参与一项需要更高持续注意力的任务时，偶发注意力的表现会提高。此外，随着任务数量或持续注意力需求的增加，持续注意力和偶发注意力之间的关联会增强。
