在他们关于运动排斥的经典研究中，Marshak和Sekuler(Science 205(1979)1399)报告了当两个不同的运动方向被分开呈现时，高达10度的排斥，然而，该研究中的受试者没有经历双眼竞争，可能是因为呈现时间很短。在本研究中，我们测量了双眼竞争中的排斥力，方法是要求受试者分别观察刺激，直到一个运动方向似乎完全支配另一个方向(Blake，Yu，Lokey，&Norman(1998))。J·科恩。神经科学，10，46-60)。我们发现，在排他性优势的过程中，运动斥力显著降低。事实上，在控制参照排斥之后--对单一运动方向的误判(Rauber&Treue(1998))。知觉，27,393-402)--我们发现在独占优势的过程中没有显著的运动排斥。这些数据表明，运动排斥可能需要多个方向的感知，而不仅仅是物理上的存在。(C)2001爱思唯尔科学有限公司。保留所有权利。
In their classic study on motion repulsion, Marshak and Sekuler (Science 205 (1979) 1399) reported a repulsion of up to 10degrees when two different directions of motion were presented dichoptically, However, subjects in that study did not experience binocular rivalry, presumably because of the brief presentation time. In the present study, we measured repulsion during binocular rivalry by requiring subjects to dichoptically view the stimuli until one direction of motion appeared to exclusively dominate the other (Blake, Yu, Lokey, & Norman (1998). J. Cogn. Neurosci., 10, 46-60). We found that motion repulsion was significantly reduced during exclusive dominance. Indeed, after controlling for reference repulsion-the misjudgment of a single direction of motion (Rauber & Treue (1998). Perception, 27, 393-402)-we found no significant motion repulsion during exclusive dominance. These data suggest that motion repulsion may require the perception, rather than merely the physical presence, of multiple directions. (C) 2001 Elsevier Science Ltd. All rights reserved.
