Abstract

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.
