Attention during visual secondary tasks in driving: Adaptation to the demands of the driving task

摘要: Abstract Visual attention in driving with visual secondary task is compared for two tasks. N  = 40 subjects completed a 1 h test drive motion-base simulator. During the drive, participants either solved an externally paced, highly demanding or self paced menu system task. The tasks were offered defined critical and non-critical situations. Eye movement behavior was analyzed both Before starting tasks, eye shows smaller standard deviation of gaze as well longer fixation durations comparison between indicates that drivers use possibilities offers: during task, they monitor scene fixations show greater position. Furthermore, independently type adapt their to demands situation. In situations direct larger proportion glance time Last, relation collisions analyzed. Results indicate go together inadequate distribution distraction. results are interpreted regarding attentional processes involved Based on similarities differences cognitive approach developed which assumes control distraction based mental situational model
