The possibility that nystagmus suppression contributes to illusory motion was investigated by measuring perceived motion of a stationary stimulus following the removal of an optokinetic stimulus. This was done because optokinetic nystagmus typically outlasts cessation of an optokinetic stimulus. Therefore, it would be expected that a stationary fixated stimulus should appear to move after removal of an optokinetic stimulus if illusory motion results from nystagmus suppression. Illusory motion was reported for a stationary fixation target following optokinetic stimulation. This motion was reported first in the same direction as the preceding induced motion, then in the opposite direction. The two directions of illusory motion following optokinetic stimulation are interpreted as resulting from the use of smooth ocular pursuit to suppress first one phase of optokinetic after nystagmus and then the reverse phase. Implications for the origins of induced motion are discussed.
通过测量视动刺激移除后静止刺激的感知运动，研究了眼球震颤抑制导致虚幻运动的可能性。这样做是因为视动性眼球震颤通常在视动刺激停止后仍会持续。因此，如果虚幻运动是由眼球震颤抑制引起的，那么在移除视动刺激后，静止的注视刺激应该会出现运动。视动刺激后，静止的注视目标出现了虚幻运动。这种运动首先被报告为与先前诱导运动相同的方向，然后是相反的方向。视动刺激后虚幻运动的两个方向被解释为是由于使用平滑眼球追踪来抑制视动性眼震的第一阶段，然后是相反阶段。讨论了对诱导运动起源的影响。
