摘　　要：为研究轿车颜色在视觉上对驾驶员脑电的影响,进行了用白、黑色轿车图片诱发事件相关脑电位的实验,结果表明:被试者对白色轿车图片识别的正确率高于黑色轿车,对白色轿车的反应时间短于黑色轿车。可以推断,大脑不同部位产生不同特征的事件相关电位数据,白色轿车对大脑诱发的脑能量高于黑色轿车,且黑色轿车对大脑神经有抑制作用。To study the vision effects of car colors on brain electricity of drivers,an experiment is performed to evoke the event-related potentials（ERPs） in brain by white and black car pictures.The results show that the correct identification rate of white car is larger than that of black car,and the average response time for white car is shorter than that for black car.It can be concluded that the different parts of cerebrum produce ERPs data with different features,the white car evokes more brain energy than black car does,and the black car tends to suppress the excitement of brain nerves.
