摘要
为预防驾驶员注意瞬脱效应导致的交通事故,首先,开展模拟驾驶任务试验,并在此过程中加入刺激颜色、时间间隔等因素,分别检测驾驶员的注意瞬脱反应;然后,基于试验数据,分析不同条件下驾驶员的驾驶行为指标（反应时和正确率）与事件相关电位（ERP）指标（P3波幅和潜伏期）的差异。结果表明：较红色警示牌和2、3 s的刺激时间间隔（SOA）,在黄色警示牌和1 s的SOA条件下驾驶行为绩效显著降低（反应时延长,正确率降低）,且P3潜伏期在顶叶区显著延长、波幅显著减小。注意瞬脱效应影响驾驶员对驾驶事件的脑内加工进程及投入的认知资源量,导致驾驶安全性降低。
For the sake of preventing traffic accidents caused by the driver＇s attentional blink,simulated driving experiments were performed. Effects of factors including stimulus color and time interval on driver＇s attentional blink were studied. Based on the experiment data,the differences in drivers＇ behavioral indexes（reaction time and accuracy） and ERP indexes（P3 amplitude and latency） under different conditions were analyzed. It was observed that compared with the other five conditions,the condition with yellow placard and 1 s SOA presented the worst behavioral performance（reaction time prolonged and accuracy decreased） and the P3 latency delayed,the P3 amplitude decreased in the parietal lobe. The results suggest that the attentional blink affects badly divers＇ brain processing of driving events and the allocation of cognitive resources,which decreases driving safety.
