Gregory's Inappropriate Constancy Scaling explanation for visual illusion was investigated. If perceptual experience with real-life edges and angles, near and far, leads to constancy scaling which is inappropriately applied to the Mueller-Lyer configuration, then configurations which are based upon angles of regard in between the two extreme field patterns would produce illusory effects between the two conventional Mueller-Lyer effects. A model representing one edge of a cubic figure, i.e., one vertical and four horizontal lines, was constructed of wooden dowel rods and photographed at predetermined angles. Transparencies based on the photographed images were then used to determine the PSE at each of these angles. Generally, we interpret out results as supportive of the theory, since PSEs increase as a function of angular change from 0 degrees to 180 degrees. The linear trend is complicated by an unexpected cubic trend, but an explanation is proposed.
对格雷戈里关于视觉错觉的不适当恒常性缩放解释进行了研究。如果对现实生活中远近的边缘和角度的感知体验导致了不适当应用于穆勒-莱尔配置的恒常性缩放，那么基于两种极端视野模式之间的注视角度的配置将在两种传统的穆勒-莱尔效应之间产生错觉效果。一个代表立方体图形一条边的模型，即一条垂直线和四条水平线，由木销棒构建而成，并在预定角度拍摄照片。然后基于拍摄图像的透明片被用于确定每个角度的主观相等点。一般来说，我们将结果解释为支持该理论，因为主观相等点随着从0度到180度的角度变化而增加。线性趋势因意外的三次趋势而变得复杂，但提出了一种解释。
