In a two-frame apparent motion display, a test grating was displaced horizontally or vertically in the presence of an inducer of which component gratings made up expanding/contracting or rotational motion as a whole. In the first experiment, we demonstrated that motion assimilation did occur for the test accompanied by the two-dimensional motion of the inducer. In the second experiment, we showed that the spatial limit of motion assimilation for expansion/contraction or rotation was large, extending over at least a visual angle of 14-21 deg in diameter, but spatial summation did not occur within the limit. The results were discussed in terms of the interaction between local motion detectors and higher-order detectors which monitor global motion of the whole stimulus pattern.
在双帧表观运动显示中，测试光栅在诱导物存在的情况下进行水平或垂直位移，诱导物的组成光栅整体上构成扩展/收缩或旋转运动。在第一个实验中，我们证明了对于伴随诱导物二维运动的测试，确实发生了运动同化。在第二个实验中，我们表明扩展/收缩或旋转的运动同化的空间限制很大，直径至少延伸超过14 - 21度的视角，但在该限制内没有发生空间总和。根据局部运动探测器和监测整个刺激模式全局运动的高阶探测器之间的相互作用对结果进行了讨论。
