| Research Abstract |
We measured the effects of monochromatic light (blue, green, yellow and red) on the time perception and the P300 event related potential to clarify the relationship between the time perception and the central nervous function. The main effect of the color of monochromatic light on the 180-s produced time interval was significant. The 180-s produced time interval in the red-light condition was found to be significantly shorter than that in the blue-light condition. The main effect of the monochromatic light condition for the P300 amplitudes was significant. The P300 amplitude in the red-light condition tended to be larger than that in the blue-light condition.
