Abstract
The cyclopean motion aftereffect refers to the illusory perception of motion in one direction evoked by the selective adaptation to real motion of disparity (binocular depth) information in the opposite direction. Employing a paradigm created by Cavanagh and Favreau (1980), this study induced cyclopean motion aftereffects using a standard-image log spiral as an adapting pattern, and a standard-image or a mirror-image log spiral as a test pattern, with the latter used to cancel local motion mechanisms. Our results reveal that the durations for both the cyclopean and luminance motion aftereffects declined when a mirror-image test pattern was used relative to when a standard-image test pattern was used. This indicates that there are two levels of cyclopean motion processing, local versus global, and that these levels are analogous to those found in luminance motion processing.
