Abstract

The simultaneous presentation of two color stimuli was used to determine whether a practical and rapid method of recording human color responses using visual evoked potentials (VEPs) can be done. Multi-color stimulation which consists of two iso-luminant color stimuli presented with a pseudorandom binary sequence (PRBS) were employed to elicit VEPs, and the first-order binary kernel of the VEPs was calculated using multi-input system analysis technique. The waveforms of the kernels elicited by the two color presentations were similar to those obtained by one color stimulation. This indicated that the simultaneous presentation of two color stimulation is effective in detecting color responses. However, the amplitudes of the kernels obtained by the two color stimulation method were different from those by one color stimulation. This may be because the effect of one color stimulus was weakened by the presence of the other color stimulus.

用多色刺激诱发的视觉诱发电位测量人的颜色反应

同时呈现两种颜色刺激，以确定是否可以使用视觉诱发电位(vep)来记录人类颜色反应的实用和快速方法。采用伪随机二值序列(pseudorandom binary sequence, PRBS)对两个等亮度颜色刺激组成的多色刺激诱发vep，利用多输入系统分析技术计算vep的一阶二值核。两种颜色刺激引起的核波与一种颜色刺激引起的核波相似。这表明同时呈现两种颜色刺激对检测颜色反应是有效的。然而，两种颜色刺激法得到的核振幅与一种颜色刺激法得到的核振幅不同。这可能是因为一种颜色刺激的效果被另一种颜色刺激的存在削弱了。
