三个实验的结果表明，视觉系统根据加工深度的绝对距离信息校正运动视差。视差是通过将阴极射线管上显示的随机点的相对运动与头部的运动相结合而产生的。在实验1中，在40厘米和80厘米的观察距离，观察者报告的运动视差相当于0.47度的双眼视差产生的表观深度。80 cm处的平均表观深度是40 cm处的2.6倍。在实验2中，同样在40 cm和80 cm的观察距离，观察者调整视差的程度，使表观深度为7.0 cm。80 cm处的平均视差范围是40 cm处的31%。在实验3中，距离范围从40厘米到320厘米，并使用了广泛的视差。随着距离和视差的增加，刚性三维表面的感知伴随着摇摆运动;在320 cm处的一些试验中，深度感知被运动感知所取代。此外，在40 cm和80 cm处，平均表观深度与观察距离成正比，但在160 cm和320 cm处不成正比。
The results of three experiments demonstrated that the visual system calibrates motion parallax according to absolute-distance information in processing depth. The parallax was created by yoking the relative movement of random dots displayed on a cathode-ray tube to the movements of the head. In Experiment 1, at viewing distances of 40 cm and 80 cm, observers reported the apparent depth produced by motion parallax equivalent to a binocular disparity of 0.47 degree. The mean apparent depth at 80 cm was 2.6 times larger than at 40 cm. In Experiment 2, again at viewing distances of 40 cm and 80 cm, observers adjusted the extent of parallax so that the apparent depth was 7.0 cm. The mean extent of parallax at 80 cm was 31% of that at 40 cm. In Experiment 3, distances ranged from 40 cm to 320 cm, and a wide range of parallax was used. As distance and parallax increased, the perception of a rigid three-dimensional surface was accompanied by rocking motion; perception of depth was replaced by perception of motion in some trials at 320 cm. Moreover, the mean apparent depths were proportional to the viewing distance at 40 cm and 80 cm but not at 160 cm and 320 cm.
