研究了亮度、色调和饱和度对相邻区域之间感知深度的影响。刺激由两个不同颜色的半球组成，受试者被要求说出哪一个看起来更近，并判断它们之间的感知深度。当两个半视野均为消色差时，感知深度随亮度差的增大而增大。一些受试者倾向于更接近地判断光明的一面，而另一些人则倾向于更接近黑暗的一面。对于非彩色-彩色组合，三种色调条件下的知觉深度没有差异，而对于彩色-彩色组合，知觉深度取决于色调组合。在“较近”判断的频率递减方面，色调顺序是红色、绿色、蓝色。当两个半球只有饱和度不同时，知觉深度随着饱和度差的增大而增加，并且更接近于色调来判断饱和度较高或较低的一侧。亮度和饱和度对观察者感知距离的影响可以归结为视野中相邻区域之间的图形-背景差异，但这一论点没有涵盖非彩色背景条件下色调的影响。
The effects of brightness, hue, and saturation on perceived depth between adjacent regions have been examined. The stimulus consisted of two hemifields of different colors, and the subject was asked to state which appeared nearer and to judge the perceived depth between them. When both hemifields were achromatic, the perceived depth was found to increase with increasing brightness difference. Some subjects tended to judge the brighter side nearer, others the darker side nearer. With the achromatic–chromatic combination, there were no differences in perceived depth among three hue conditions, whilst with the chromatic–chromatic combination the perceived depth depended on hue combination. In terms of decreasing frequency of ‘nearer’ judgments the hue order was red, green, blue. When the two hemifields differed only in saturation, the perceived depth increased with increasing saturation difference, and whether the more saturated or the less saturated side was judged nearer depended on hue. It is argued that the effects of brightness and saturation on perceived distance from the observer can be attributed to figure–ground differentiation between adjacent regions in the visual field; but this argument does not cover the effect of hue under achromatic background conditions.
