本研究调查了12名色觉缺陷的受试者与12名正常三色视觉的受试者相比，是否对计算机屏幕上显示的彩色刺激具有上级视觉辨别力。参与者被要求区分圆形图案与其他图案，其中纹理元素在方向和厚度上与背景不同。在一种情况下，刺激物是单色的，绿色或红色;在另一种情况下，刺激物是用覆盖在图案上的绿色和红色马赛克进行颜色标记的。色觉缺陷的参与者在彩色视觉条件下选择正确的刺激物的速度与在单色条件下一样快。然而，正常的色觉参与者在颜色混合的条件下比在单色条件下花更长的时间来选择正确的选择。这些结果表明，色觉缺陷的参与者可能有一个上级的视觉能力来区分颜色的刺激。
This study investigated whether 12 participants with color-vision deficiency had Superior Visual discrimination of color-camouflaged stimuli shown on a computer screen compared with 12 participants with normal trichromatic vision. Participants were asked to distinguish a circular pattern from other patterns in which textural elements differed from the background in orientation and thickness. In one condition, stimuli were single-colored, green or red; in the other condition, stimuli were color camouflaged with a green and red mosaic overlaid onto the pattern. Color-vision deficient participants selected the correct stimuli in the color-camouflaged condition as quickly as they did in the single-colored condition. However, normal color-vision participants took longer to select the correct choice in the color-camouflaged condition than in the single-colored condition. These results suggest that participants with color-vision deficiency may have a superior visual ability to discriminate the color-camouflaged stimuli.
