【摘要】：為探究疲勞對駕駛員心理旋轉(zhuǎn)能力的影響機制,首先開展2 h模擬駕駛?cè)蝿?wù)試驗,以誘發(fā)駕駛疲勞,并在模擬駕駛?cè)蝿?wù)前后,分別測定駕駛員的心理旋轉(zhuǎn)能力;然后基于試驗數(shù)據(jù),分析駕駛疲勞前后心理旋轉(zhuǎn)能力行為績效(反應(yīng)時間、正確率)和腦電事件相關(guān)電位(ERP)成分(P3波幅和潛伏期)的變化及其差異。試驗發(fā)現(xiàn),駕駛疲勞引起行為績效顯著降低(反應(yīng)時延長,正確率降低),腦電ERP的P3成分波幅在頂葉區(qū)顯著下降、潛伏期顯著延長。上述結(jié)果表明:疲勞影響了駕駛員在心理旋轉(zhuǎn)過程中對認(rèn)知資源的分配和加工信息的速度,導(dǎo)致心理旋轉(zhuǎn)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.
