地面表面和其他环境表面（天花板和侧壁）在确定感知布局的相对有效性进行了研究，在五个实验和真实世界的演示。在前三个实验中，两个垂直或水平的柱子被定位在两个表面之间（所有三个实验中的地面和天花板，实验1中的左墙和右墙），并且操纵光学接触，使得两个表面提供关于柱子的相对距离的矛盾信息。观察员判断这两个职位中哪一个似乎更接近。在实验4中，为了控制做出距离判断的柱子上的高度，在不同高度的两个垂直柱子上都贴上一个蓝点，观察者判断哪个点看起来更近。实验5中，用两个灰色椭圆代替柱子，以消除规则形状和纹理的影响。我们的研究结果是：（1）在所有四个测试表面中，观察者都表现出根据地面提供的光学接触信息做出反应的偏好-地面优势效应，（2）这种效应不依赖于图像中柱子的高度，（3）随着场景从地面/天花板方向倾斜，地面优势效应减弱，（4）这种影响不是由于判决的地点。
The relative effectiveness of the ground surface and other environmental surfaces (the ceiling and sidewalls) in determining perceived layout was investigated in five experiments and a real-world demonstration. In the first three experiments, two vertical or horizontal posts were positioned between two surfaces (ground and ceiling in all three experiments, left wall and right wall in Experiment 1), and optical contact was manipulated so that the two surfaces provided contradictory information about the relative distances of the posts. Observers judged which of the two posts appeared to be closer. In Experiment 4, to control the height on the posts at which the distance judgments were made, a blue dot was attached to both vertical posts at varying heights and observers judged which dot appeared closer. In Experiment 5, the posts were replaced by two gray ellipses to eliminate the effects of the regular shape and texture. Our findings were that (1) among all four surfaces tested, observers showed a preference to respond according to the optical contact information provided by the ground surface-a ground dominance effect, (2) this effect did not depend on the height of the posts in the image, (3) as the scene was tilted away from a ground/ceiling orientation, the ground dominance effect decreased, and (4) this effect was not due to the location of the judgment.
