A paper by Rabin et al. (1994) Vision Research, 34, 2657-2671, claimed that spatially extensive grating stimuli could be used to generate chromatic-specific visual evoked potentials from subjects assumed to have standard spectral sensitivity and tritanopic confusion lines. Here we demonstrate that such spatially extensive stimuli may generate responses which are contaminated by luminance-contrast intrusions. Such intrusions are mainly due to chromatic aberrations and are compounded by the abovementioned assumptions. Claims regarding the chromatic selectivity of VEPs must, therefore, be substantiated by establishing correlations with the known properties of the chromatic system.
拉宾等人（1994年）发表于《视觉研究》第34卷，第2657 - 2671页的一篇论文声称，对于假定具有标准光谱敏感度和蓝色混淆线的受试者，空间上广泛的光栅刺激可用于产生特定颜色的视觉诱发电位。在此我们证明，这种空间上广泛的刺激可能会产生被亮度对比度干扰所污染的反应。这种干扰主要是由于色差引起的，并且因上述假设而更加复杂。因此，关于视觉诱发电位颜色选择性的说法必须通过与颜色系统的已知特性建立相关性来证实。
