Abstract
One remarkable phenomenon reported in the literature on motion perception is called the motion aftereffect (MAE), which refers to the illusion of motion in a given direction following adaptation to real motion in the opposite direction. The purpose of the present study was to investigate the induction of the MAE using an optic flow motion stimulus, which was created from simulated self-movement through a real-world perspective scene. Specifically, the effect of adaptation using the central versus peripheral visual field on the duration of the optic flow MAE was investigated. In doing so, the areas of the central versus peripheral adapting stimulus were equated by scaling for cortical magnification. Results showed that the duration of the MAE was shorter when the adapting optic flow motion was presented in the peripheral visual field than when it was presented centrally. These results were interpreted as reflecting a more transient response in the automatic gain control mechanisms in the motion pathways projecting from the peripheral retina.
