Luminance edges seem to have an important role in visual feature binding and, more specifically, in visual completion because luminance differences are important for the perception of depth. We investigated this claim in two experiments in which the primed-matching paradigm was used. In Experiment 1, we investigated conditions under which either a partly occluded shape or an occluder was isoluminant with respect to the background. In Experiment 2, the partly occluded shape and the occluder were isoluminant with respect to each other. Evidence was found for visual completion in all cases, and we therefore conclude that luminance edges are not essential for visual completion.
亮度边缘似乎在视觉特征整合中，更具体地说，在视觉完形中起着重要作用，因为亮度差异对深度感知很重要。我们在两项使用启动匹配范式的实验中对这一观点进行了研究。在实验1中，我们研究了部分被遮挡的形状或遮挡物与背景等亮度的条件。在实验2中，部分被遮挡的形状和遮挡物彼此等亮度。在所有情况下都发现了视觉完形的证据，因此我们得出结论，亮度边缘对于视觉完形并非必不可少。
