两只眼睛的视图一起包含更多的空间或几何信息，而不是从一个Vantage位置忠实地表示。正如在画布上不可能画出一幅“真实”的画一样，视觉系统也不可能画出一幅“忠实的视觉”画。我们进行了几个心理物理实验使用立体显示器。方向判断的实验结果表明，视觉系统解决了问题的拟合两个眼睛的意见，在其整体上，到一个单一的循环视图通过“位移”和“压缩”，感知，视野的一部分。形状判断的实验结果表明，视觉系统有一个“校正”机制，以调整的结果，方向位移和压缩。我们假设，这种“纠正”机制的操作是由闭塞的图片线索触发的，这种机制是负责Kanizsa和Poggendorff错觉时，三维刺激画一张纸。
Two eyes' views together contain more spatial or geometric information than what can be represent faithfully from one vantage point. Just as it is impossible to paint an "authentic" picture on canvas, it is impossible for the visual system to make a "faithful visual" picture. We conducted several psychophysical experiments using stereoscopic displays. Experimental results on judging direction showed that the visual system solves the problem of fitting the two eyes' views, in their entirety, into a single cyclopean view by "displacing" and "compressing", perceptually, a portion of the visual field. The experimental results on judging shape showed that the visual system has a "correcting" mechanism to adjust for the consequences of the directional displacement and compression. We hypothesize that the operation of this "correcting" mechanism is triggered by the pictoral cue of occlusion and that this mechanism is responsible for the Kanizsa and Poggendorff illusions when three-dimensional stimuli are drawn a sheet of paper.
