三个实验研究了当一对线段出现在盲点的相对两侧时，盲点处知觉完成容忍度的各向异性。感知完成的容限被定义为当已经发生线的感知完成时在盲点的相对侧上的线段之间的刺激属性的最大差异。在实验1、2和3中，线段之间的错位、方向差和亮度差分别被用作刺激属性。结果表明，线段水平和垂直结构的知觉完成容限各向异性。垂直优势，这意味着在垂直配置比在水平配置的更大程度的公差，观察到的错位和方向差异，而水平优势，这意味着在水平配置比在垂直配置的更大程度的公差，观察到的亮度差。我们讨论了可能的起源的各向异性的容忍知觉完成盲点。(C)2007爱思唯尔有限公司保留所有权利。
Three experiments examined anisotropies of tolerance of perceptual completion at the blind spot when a pair of line segments was presented on opposite sides of the blind spot. The tolerance of perceptual completion is defined as the maximum difference in a stimulus attribute between the line segments on opposite sides of the blind spot when perceptual completion of a line has occurred. The misalignment, orientation difference, and luminance difference between the line segments were used as the stimulus attributes in Experiments 1, 2, and 3, respectively. The results showed anisotropies of the tolerance of perceptual completion between horizontal and vertical configurations of the line segments. Vertical superiorities, which imply a greater extent of tolerance in the vertical configuration than that in the horizontal configuration, were observed for misalignment and orientation difference, while horizontal superiority, which implies a greater extent of tolerance in the horizontal configuration than that in the vertical configuration, was observed for luminance difference. We discussed possible origins of the anisotropy of the tolerance of perceptual completion at the blind spot. (C) 2007 Elsevier Ltd. All rights reserved.
