The aim of this study is to explore the influence of the degree and location of the danger of traffic hazards on the neural reaction process.
26 automobile drivers were asked to look at the pictures and press buttons on the pictures unrelated to traffic. Electroencephalography responses to traffic-related images were recorded and analyzed.
It was found that danger in the central visual region induced a larger amplitude of the N100 component than in the peripheral visual region and the trend of different hazard levels was consistent. The danger in the central visual area also induced a larger amplitude of the P200 component than in the peripheral vision area. In addition, when the danger appeared in the central visual area (0°), the P200 amplitude induced by the low-hazard situation was smaller than that of the high-hazard situation. When the danger appeared in the peripheral visual area (7°), the P200 amplitude induced by the low-hazard situation was larger than that of the high-hazard situation. Finally, the presence of danger evoked a larger amplitude of the P300 component in the peripheral visual area than in the central visual area and the P300 amplitude was larger in the low-hazard situation than in the high-hazard situation.
The results suggest that hazards are more easily processed in the central visual area during the early stage of automatic perception. In the later hazard evaluation stage, the hazard in the central visual area and the high-hazard situation were more easily processed.
本研究旨在探讨交通危险的危险程度和位置对神经反应过程的影响。
要求 26 名汽车驾驶员观看与交通无关的图片并按下图片上的按钮。记录和分析与交通相关的图片的脑电图反应。
结果发现，中央视觉区域的危险引起的 N100 成分幅度大于外周视觉区域，不同危险水平的趋势一致。中央视觉区的危险还引起 P200 成分的幅度大于外周视觉区。此外，当危险出现在中央视觉区（0°）时，低危险情况下诱导的 P200 幅度小于高危险情况。当危险出现在外周视觉区（7°）时，低危险情况下诱导的 P200 幅度大于高危险情况。最后，危险的存在在外周视觉区引起比中央视觉区更大的 P300 成分幅度，并且低危险情况下的 P300 幅度大于高危险情况。
结果表明，在自动感知的早期阶段，中央视觉区的危险更容易被处理。在危险评估的后期阶段，中央视觉区的危险和高危险情况更容易被处理。
