The Analysis on Vehicle Color Evoked EEG Based on ERP Method

As is known, it is of extreme importance to enhance the traffic safety by all means, of which vehicle colors may serve as one of the key influential factors to be considered. To study the different brain activities on vision of different colored cars, the event-related brain potentials (ERPs) were induced using the red and blue car pictures. The average response accuracy rate of red car is higher, and the average latency time of red car is shorter. At the same time, red/blue car pictures have different influences on different electrical potentials. It is obtained that the brain energy evoked by red car is larger than that of blue car. It is concluded that red car picture statistically tends to explode the excitement of visual nerves than blue car.
