In three experiments on apparent motion, subjects were to press a computer key as quickly as possible either when the apparently moving stimulus passed the midpoint of its trajectory or when it reached the endpoint. If motion is perceived as a trajectory through a series of spatial locations, and if this type of percept is the basis of deliberate responding (assumptions that can be considered Cartesian in origin), then reaction times should be faster to the midpoint than to the endpoint. In contrast to these assumptions, there was no difference between reaction times to these two points. Alternative accounts of the results are discussed.
在三项关于似动现象的实验中，当明显移动的刺激物经过其轨迹的中点或到达终点时，受试者要尽快按下电脑按键。如果运动被视为通过一系列空间位置的轨迹，并且如果这种感知类型是刻意反应的基础（这些假设在起源上可被视为笛卡尔式的），那么对中点的反应时间应该比对终点的反应时间更快。与这些假设相反，对这两个点的反应时间没有差异。文中讨论了对结果的其他解释。
