【摘要】：駕駛是一項需要持續(xù)監(jiān)控視覺環(huán)境，不斷過濾視覺信息以保證注意最重要線索的情境。駕駛中駕駛員不僅需要注意路面信息，同時還要監(jiān)控道路兩側(cè)的情境，并且經(jīng)常出現(xiàn)搜索目標物的情況。而對目標物的搜索會引起注意分散和信息加工能力的下降，進而影響駕駛員的整體績效。 本研究旨在探索道路負荷和視覺搜索任務(wù)對駕駛員無意視盲現(xiàn)象的影響，借用眼動技術(shù)，對39名新手駕駛員和17名經(jīng)驗駕駛員的眼動數(shù)據(jù)進行分析，系統(tǒng)考察了簡單路況和復(fù)雜路況，，行人非預(yù)期刺激和尾燈非預(yù)期刺激，新手駕駛員和經(jīng)驗駕駛員，低認知負荷和高認知負荷，以及非預(yù)期問題的相關(guān)性對駕駛員無意視盲現(xiàn)象的影響。實驗結(jié)果指出，隨著知覺負荷和認知負荷水平的提高，駕駛員無意視盲比率升高，對非預(yù)期目標的檢測率降低，即任務(wù)無關(guān)刺激的知覺水平，取決于任務(wù)相關(guān)刺激的負荷水平。本研究得出的具體結(jié)論如下： 1.復(fù)雜路況的注視點的持續(xù)時間低于簡單路況，而總注視次數(shù)多于簡單路況。 2.被試回答行人非預(yù)期問題的正確率高于尾燈非預(yù)期問題的正確率。簡單路況條件下，被試對行人非預(yù)期刺激的注視點的持續(xù)時間和總注視時間多于尾燈非預(yù)期刺激，而復(fù)雜路況條件下，被試對尾燈非預(yù)期刺激的總注視時間和總注視次數(shù)都多于行人非預(yù)期刺激。 3.被試在低認知負荷條件下的總注視時間和總注視次數(shù)都多于高認識負荷條件。隨著認知負荷水平的提高，被試回答行人非預(yù)期問題的正確率下降，并且對行人非預(yù)期刺激的總注視時間和總注視次數(shù)都減少。 4.經(jīng)驗駕駛員回答行人相關(guān)問題的正確率高于不相關(guān)問題的正確率。 5.與新手駕駛員相比，經(jīng)驗駕駛員回答簡單路況中行人問題的正確率更高，而新手駕駛員注視點的持續(xù)時間長于經(jīng)驗駕駛員。
[Abstract]:Driving is a situation that requires continuous monitoring of the visual environment and constant filtering of visual information to ensure attention to the most important clues. Drivers not only need to pay attention to road information, but also monitor the situation on both sides of the road. The object search will cause the distraction of attention and the decline of information processing ability, which will affect the overall performance of the driver. The purpose of this study was to explore the effect of road load and visual search task on drivers' unintentional blindness, and to analyze the eye movement data of 39 novice drivers and 17 experienced drivers by using eye movement technology. Simple and complex road conditions, pedestrian unexpected stimuli and taillight unanticipated stimuli, novice drivers and experienced drivers, low cognitive load and high cognitive load were systematically investigated. And the influence of the correlation of unexpected problems on drivers' unintentional blindness. The experimental results show that with the increase of perceived load and cognitive load, the ratio of unintentional blindness increases and the detection rate of unexpected target decreases, that is, the perceived level of task-independent stimulus depends on the load level of task-related stimulus. The specific conclusions of this study are as follows: 1. The duration of fixation point in complex road condition is lower than that in simple road condition, and the total fixation frequency is more than that in simple road condition. The correct rate of answering pedestrian unexpected questions was higher than that of taillight unexpected questions. Under simple road condition, the duration and total fixation time of the fixed point of pedestrian unexpected stimulation were longer than that of tail light unanticipated stimulation, while under complex road condition, the duration and total fixation time of pedestrian unanticipated stimulation were more than that of tail light unanticipated stimulation, but under complex road condition, The total fixation time and the total fixation times of the subjects were more than that of the pedestrian unanticipated stimuli. 3. 3. The total fixation time and the total fixation times of subjects under low cognitive load were higher than those of high cognitive load. With the increase of cognitive load level, the correct rate of answering pedestrian unexpected questions decreased, and the total fixation time and the total fixation times of pedestrian unexpected stimulation decreased. 4. The correct rate of experienced drivers answering pedestrian related questions is higher than that of uncorrelated questions. 5. 5. Compared with novice drivers, experienced drivers have a higher correct rate of answering pedestrian questions in simple road conditions, while novice drivers have longer fixation points than experienced drivers.
