Interactions between spatial and kinetic dimensions in movement aftereffect

In some conditions, the surface of the test figure on which one sees an aftereffect of movement does not fit with that part of the visual field previously adapted to a movement. Such an effect, called kinetic-figural effect, may be conceived of as resulting from an interaction between two perceptual systems, each one giving specific information: one for the kinetic aspects which are spatially defined, the other for the spatial relationship inside the visual field. Experiments are presented which indicated the validity of a “law of location” for a movement aftereffect, together with some effects of the spatial relationships between adapting and test fields upon the movement aftereffect.
