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: For the sake of investigating the influence of fatigue on the mental fatigue of drivers, ERP-based experiments were carried out. In the experiments, the mental rotation ability of drivers was determined before and after they fulfilling a 2-hour simulated driving task respectively. Based on the experimental data, the change and variability in behavioral performance (reaction time, accuracy) and ERP component (amplitude and latency of P3) before and after the driving fatigue were analyzed. It was found that driving fatigue decreased the behavior performance significantly (delayed reaction time, decreased accuracy), and the ERP component P3's amplitude decreased and latency delayed significantly in the parietal lobe. The conclusion the authors arrived at is that fatigue influences the allocation of cognitive resources and the speed of information processing of drivers in mental rotation process, resulting in undermining the mental rotation ability.
