表面的表观亮度可以被它所嵌入的空间环境强烈调节。这种情境依赖的早期理论强调了感知边界对比的低级机制的作用，而最近一些作者强调了感知组织在决定感知亮度方面的作用。怀特描述了一种最简单、理论上最具挑战性的轻错觉。这种错觉已经用各种不同的模型来解释，从低级过滤器输出到提取表面中层表示的计算。在这里，我提出了一种新的方法来确定形成这种错觉的组织力量。我展示了White模式的空间背景不仅改变了均匀目标斑块的表观亮度，而且还可以引起纹理目标区域的图像-背景关系的戏剧性反转。这些现象为割裂在引起怀特效应中所经历的亮度错觉中的作用提供了新的证据。
The apparent lightness of a surface can be strongly modulated by the spatial context in which it is embedded. Early theories of such context dependence emphasized the role of low-level mechanisms that sense border contrast, whereas a number of recent authors have emphasized the role of perceptual organization in determining perceived lightness. One of the simplest and most theoretically challenging lightness illusions was described by White. This illusion has been explained with a variety of different models, ranging from low-level filter outputs to computations underlying the extraction of mid-level representations of surfaces. Here, I present a new method for determining the organizational forces that shape this illusion. I show that the spatial context of White's pattern not only transforms the apparent lightness of homogeneous target patches, but can also induce dramatic inversions of figure-ground relationships of textured target regions. These phenomena provide new evidence for the role of scission in causing the lightness illusion experienced in White's effect.
