Depth perception is known to be impaired for chromatic equiluminant patterns. To investigate this phenomenon I have compared the effects of binocularly presented stimuli in the form of stripes, which contain only luminance information with similarly presented stimuli which contain only chromatic information. Observations of the reported percepts for the two conditions demonstrate that mechanisms of colour vision can impede stereopsis based on binocular fusion when the chromatic stripes are at, or even near, equiluminance, provided that their saturation is high. This observation is consistent with inhibitory interactions within the chromatic-sensitive neuronal groupings in the visual cortex.
已知对于彩色等亮度图案，深度感知会受损。为了研究这一现象，我比较了以条纹形式双眼呈现的刺激（仅包含亮度信息）与同样呈现的仅包含颜色信息的刺激的效果。对这两种情况报告的感知的观察表明，当彩色条纹处于甚至接近等亮度且饱和度高时，颜色视觉机制会基于双眼融合阻碍立体视觉。这一观察结果与视觉皮层中对颜色敏感的神经元分组内的抑制性相互作用一致。
