Human peripheral vision is differently processed in the brain compared to the foveal vision. This study investigates the motion perception in the periphery, specifically if one would detect any lagging or change in the velocity of the motion stimulus presented in the periphery, when an identical stimulus is presented in the foveal region. In this study, the subjects saw three 10 seconds visual stimuli with one video clip situated in the center and the other in one of the three peripheral positions, and were asked to foveate on the center and report if perceive any lag and/or velocity change in the peripheral video. From the experiment, a significant effect of the positions on the subject's perceived lag was found but not for the effect of the positions on the perceived change in velocity. The result suggests that humans perceives a pure lagging effect in their peripheral vision more readily than a velocity slowing effect, which corroborates the result from prior study.
