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.
