在观察一个物体在一个隐含的旋转，主题的短期视觉记忆的物体的位置是扭曲的旋转方向。先前对这种表象动量效应的解释强调了与物理动量的类比。本研究提供了一个更普遍的观点：位置记忆受到与未来事件过程相关的预期过程的影响。在实验1中，被试呈现一个隐含的周期性事件，其中一个矩形来回旋转。当可以预期隐含旋转中的方向改变时，内存失真大小降回零。实验2拒绝了另一种解释实验1中的研究结果在增强位置记忆所造成的重复演示的记忆模式的方向在同一审判。在实验3中，隐含事件的周期由速度而不是方向的变化来标记。对速度突然增加的预期会导致更大的记忆偏移。我们的结论是，感知系统预期的基础上表示的高阶事件结构，而不是局部运动特性的事件过程。
After viewing an object in an implied rotation, subjects' short-term visual memory for the object's position is distorted in the direction of rotation. Previous accounts of this representational momentum effect have emphasized the analogy to physical momentum. This study provides a more general perspective: Position memory is influenced by anticipatory processes related to the future event course. In Experiment 1, subjects are presented with an implied periodical event in which a rectangle rotates back and forth. When a direction change in the implied rotation can be anticipated, memory distortion size drops back to zero. Experiment 2 rejects an alternative explanation for the findings of Experiment 1 in terms of enhanced position memory caused by repeated presentations of the memory pattern orientation within the same trial. In Experiment 3, the periods of the implied event are marked by changes in velocity rather than direction. The anticipation of a sudden velocity increase leads to a larger memory shift. We conclude that the perceptual system anticipates the event course on the basis of a representation of the higher order event structure rather than the local motion characteristics.
