即使在光线充足的环境中，位于地平面上的形状也经常会有很大的感知失真。这些失真发生在位置感知不准确的条件下。四个假设被认为是调和这些看似矛盾的结果，之后，2个实验报告，进一步支持其中之一-感知的形状和感知的位置有时是分离的。2个实验表明，而感知的位置并不取决于是否观看是单眼或双眼（当其他距离线索丰富），感知的形状变得更加真实，当观看是双眼。这意味着对形状的感知并不完全受定义形状的顶点的感知位置的约束。
There are often large perceptual distortions of shapes lying on the ground plane, even in well-lit environments. These distortions occur under conditions for which the perception of location i saccurate. Four hypotheses are considered for reconciling these seemingly paradoxical results, after which 2 experiments are reported that lend further support to 1 of them--that perception of shapeand perception of location are sometimes dissociable. The 2 experiments show that whereas perception of location does not depend on whether viewing is monocular or binocular (when other distance cues are abundant), perception of shape becomes more veridical when viewing is binocular. This means that perception of shape is not fully constrained by the perceived locations of the vertices that define the shape.
