title: Background spatial frequency influences perception of luminance-based apparent movement.
abstract: Apparent movement occurs when stimulus figures are presented at different spatial locations at different times. In the present studies, the periodicity of the background upon which stimuli were presented was manipulated. Subjects viewed a bistable movement display presented on a background consisting of a variable-frequency grating. The type of movement perceived varied systematically with the spatial frequency of the background, suggesting that more than the target stimuli are processed in the generation of apparent movement.
