以前有许多与运动物体相关的定位误差的报告（例如闪光滞后效应，Frohlich效应，代表性动量）。在四个实验中，探索了一种新形式的错位-起始排斥效应（ORE），其中误差总是沿着观察到的运动路径返回。也就是说，当观察者被要求定位运动物体的初始起始和最终偏移位置时，到目前为止，他们产生的最大和最系统的误差是沿着正确的运动路径沿着过早地放置起始点。通过比较，与运动路径正交的误差和定位偏移点的误差是最小的。当运动是隐含的而不是连续的时，误差也非常小。可以在固定和不固定的情况下观察到ORE。并且与其他的错位效应一样，显示出对方向和速度的某种依赖性。由于这些研究中最明显的预测是基于先前的错误定位报告和视觉系统的已知特性，将是向前而不是向后的错误，因此讨论将集中在可能导致观察到的结果模式的机制类型上。
There have been many previous reports of mislocalization associated with moving objects (e.g. flash-lag effect, Frohlich effect, representational momentum). Across four experiments, a new form of mislocalization - the onset repulsion effect (ORE) - is explored in which the error is always back along the observed path of motion. That is, when observers are asked to localize both the initial onset and the final offset positions of a moving object, by far the largest and most systematic error they make is in placing the onset point too early along the correct path of motion. Errors orthogonal to the path of motion and errors in localizing the offset point are minimal by comparison. Errors are also very small when motion is implied rather than continuous. The ORE can be observed with and without fixation. and as with other mislocalization effects, shows some dependence on direction and velocity. As the most obvious prediction in these studies, based on previous reports of mislocalization and the known properties of the visual system, would be for forward rather than backward errors, discussion will focus on the type of mechanism that may have given rise to the observed pattern of results.
