到目前为止，已经指出，运动表示在运动轨迹中完成，并且运动表示在运动轨迹中的特定时间和空间干扰单个物理输入。然而，它还没有得到充分的研究，内部的运动表示是否可以与多个物理输入跨时间和空间的运动轨迹。因此，目前的研究调查是否时空相干运动知觉可以建立在涉及运动序列的时空逆转的情况下。在一个五点运动显示，我们发现，运动方向知觉的最后两个刺激包含时空逆转是一致的前三个刺激。当运动轨迹的形状（向上或向下）随机改变时，会发生这种感知运动方向反转的失败。此外，我们证实，一个先前的刺激（三点运动）是足以产生的失败，感知运动方向逆转，和先前的刺激饱和时，先前的序列包含两个或更多的刺激的效果。这些发现表明，灵活的内部运动表征机制重组运动轨迹的时空不规则性，并建立时空连贯的运动知觉。
Thus far, it has been pointed out that motion representation is completed in motion trajectory, and that motion representation interferes with a single physical input at a specific time and space in the motion trajectory. However, it has not been fully investigated whether the internal motion representation could interact with multiple physical inputs across time and space in motion trajectory. Thus, the current research investigated whether spatiotemporally coherent motion perception could be established in a situation involving the spatiotemporal reversal of motion sequences. In a five-point motion display, we found that the motion direction perception of the last two stimuli containing the spatiotemporal reversal was consistent with three preceding stimuli. This failure to perceive motion direction reversal occurred when the shapes of motion trajectory (to upper or lower) were randomly changed. Moreover, we confirmed that one preceding stimulus (three-point motion) was sufficient to produce the failure to perceive motion direction reversal, and the effect of the prior stimuli saturated when the preceding sequence contained two or more stimuli. These findings suggest that the flexible internal motion representation mechanisms reorganize the spatiotemporal irregularities in motion trajectory and establish spatiotemporally coherent motion perceptions.
