鲁宾最初指出，视觉将人物与背景区分开来，即使在二维(2-D)显示器中也是如此。他和其他完成主义者1在反思的基础上提出，人物被视为具有确定的形状，而与之相连的地面则被视为无形的，尽管与人物一样有分裂的轮廓。在前一篇文章中，2我们介绍了最近的性能研究，表明图形和背景之间的分界线自动分配给人物形状，即使受试者试图只判断分界线本身。因此，如果测试刺激的边缘被分配到与预先分割的人物形状相同的方向上，则对分割边缘的识别更好。我们认为，单边边缘分配提供了一种有效的启发式方法来获得任何二维图像的可能的三维(3-D)源。在这篇综述中，我们探索了这种边缘分配对形状表征的影响序列，并提出了为什么只有图形被赋予形状的原因。
Rubin originally noted that vision distinguishes figures from back ground, even within two-dimen sional (2-D) displays. He and other Gestaltists1 suggested on the basis of introspection that figures are seen as having a definite shape, whereas ad joining ground is seen as shapeless despite the dividing contour in com mon with the figure. In a previous article,2 we presented recent perfor mance studies showing that the di viding edge between figure and ground is automatically assigned to the figurai shape, even when sub jects attempt to judge just the divid ing edge itself. As a result, recogni tion of the dividing edge is better if a test stimulus has this edge assigned in the same direction as in the pre ceding figurai shape. We argued that one-sided edge assignment provides an efficient heuristic for deriving the likely three-dimensional (3-D) source of any 2-D image. In the present review, we explore the con sequences of such edge assignment for shape representation and suggest an account for why only figures ap pear shaped.
