以前曾有报道，长时间的单向平滑追踪往往会产生负面的运动后效（MAE）。这被认为是由在追踪过程中静止的环境轮廓的视网膜图像运动引起的，该视网膜图像运动随后在追踪方向上产生主要运动后效。周边MAE然后在静止的跟踪目标中引起运动，导致在相反方向上的虚幻运动。我们已经发现，负MAE也产生时，适应领域是没有任何轮廓。此外，移动纹理背景的存在与平滑追踪相结合产生了MAE，其方向与诱导运动假设不一致。由于本研究中所有运动后效的例子都与实验的追踪方面有关，而不是与背景轮廓的任何相互作用有关，因此提出错觉运动具有视觉决定因素。初步提出了一个方案，其中长时间追踪适应（追踪后眼震）后未登记的眼漂移的注视抑制产生了适应后运动错觉。
It has been previously reported that prolonged unidirectional smooth pursuit often produces a negative motion aftereffect (MAE). This was believed to be caused by retinal image motion of stationary environmental contours during pursuit which subsequently produced a primary motion aftereffect in the tracking direction. The peripheral MAE then induced motion in the stationary tracking target resulting in illusory movement in the opposite direction. We have found that a negative MAE is also produced when the adapting field is devoid of any contours. Furthermore, the presence of a moving textured background in conjunction with smooth pursuit produced an MAE whose direction was inconsistent with the induced motion hypothesis. Since all examples of motion aftereffects in this study were associated with the pursuit aspect of the experiment rather than any interactions with background contours, it was proposed that the illusory motion had an oculomotor determinant. A scheme was tentatively outlined in which fixation suppression of an unregistered ocular drift following prolonged pursuit adaptation (pursuit afternystagmus) produced the post-adaptive motion illusions.
