Prolonged inspection of a three-dimensional corrugated surface resulted in a successive contrast effect, or aftereffect, of depth, whereby a subsequently-viewed physically-flat test surface appeared to be corrugated in depth with the opposite phase to the adapting surface. The aftereffect occurred both when the depth was specified by motion parallax, in the absence of all other sources of depth information, and when it was specified solely by stereoscopic information. The depth aftereffect was measured by 'nulling' the apparent depth in the test surface with physical relative motion or binocular disparity until the test surface appeared flat. Up to 70% of the depth in the adapting surface was necessary to null the aftereffect. Simultaneous contrast effects in the perception of three-dimensional surfaces were used to investigate the spatial interactions that exist in the processing of motion-parallax and stereoscopic information. A physically vertical surface appeared to slope in depth in the opposite direction to the slope of a surrounding surface. In this case up to 50% of the slope of the inducing surface was necessary to null the contrast effect. Similar results were again obtained for motion-parallax and stereoscopic depth.
对三维波纹表面进行长时间观察会产生连续的深度对比效应或后效应，即随后观察到的物理上平坦的测试表面在深度上似乎呈波纹状，且相位与适应表面相反。当深度由运动视差指定（在没有所有其他深度信息来源的情况下）以及当深度仅由立体视觉信息指定时，都会出现后效应。深度后效应通过用物理相对运动或双眼视差“消除”测试表面的表观深度来测量，直到测试表面看起来是平坦的。需要适应表面中高达70%的深度来消除后效应。利用三维表面感知中的同时对比效应来研究运动视差和立体视觉信息处理中存在的空间相互作用。一个物理上垂直的表面在深度上似乎朝着与周围表面斜率相反的方向倾斜。在这种情况下，需要诱导表面斜率的高达50%来消除对比效应。对于运动视差和立体视觉深度，再次获得了类似的结果。
