【摘要】:为探究疲劳对驾驶员心理旋转能力的影响机制,首先开展2 h模拟驾驶任务试验,以诱发驾驶疲劳,并在模拟驾驶任务前后,分别测定驾驶员的心理旋转能力;然后基于试验数据,分析驾驶疲劳前后心理旋转能力行为绩效(反应时间、正确率)和脑电事件相关电位(ERP)成分(P3波幅和潜伏期)的变化及其差异。试验发现,驾驶疲劳引起行为绩效显著降低(反应时延长,正确率降低),脑电ERP的P3成分波幅在顶叶区显著下降、潜伏期显著延长。上述结果表明:疲劳影响了驾驶员在心理旋转过程中对认知资源的分配和加工信息的速度,导致心理旋转能力降低。
[Abstract]:In order to explore the influence mechanism of fatigue on the mental rotation ability of drivers, a 2-hour simulated driving task test was carried out to induce driving fatigue, and the psychological rotation ability of drivers was measured before and after the simulated driving tasks. Then, based on the experimental data, the changes and differences of behavior performance (reaction time, accuracy) and (ERP) component (P3 amplitude and latency) of EEG event-related potentials before and after driving fatigue were analyzed. It was found that driving fatigue induced significantly decreased behavioral performance (prolonged reaction time and lower accuracy), significantly decreased P3 component amplitude in parietal lobe and prolonged latency of EEG. The above results show that fatigue affects the speed of cognitive resource allocation and processing information in the process of mental rotation and leads to the decrease of mental rotation ability.
