Is a retinal representation of an edge necessary to constrain the reach of color filling-in? If so, then color filling-in should not be constrained by illusory contours, because they do not exist at a retinal level. Alternatively, if color filling-in is constrained by contours at a perceptual level of neural representation, regardless of whether there is a retinal representation, then color filling-in should be constrained by illusory contours. To address this question, a variety of real luminance edges and illusory contours were presented under conditions designed to cause color filling-in. The results showed that illusory contours bounded the reach of color filling-in. A neural representation of a contour may first exist at a retinal level or a cortical level; in either case, the contour exists at a perceptual level and bounds color filling-in.
视网膜上边缘的表征对于限制颜色填充的范围是否必要？如果是这样，那么颜色填充不应受虚幻轮廓的限制，因为它们在视网膜层面并不存在。或者，如果颜色填充在神经表征的感知层面受轮廓限制，无论是否存在视网膜表征，那么颜色填充都应受虚幻轮廓的限制。为了解决这个问题，在旨在引发颜色填充的条件下呈现了各种真实亮度边缘和虚幻轮廓。结果表明，虚幻轮廓限制了颜色填充的范围。轮廓的神经表征可能首先存在于视网膜层面或皮层层面；无论哪种情况，轮廓都存在于感知层面并限制颜色填充。
