Two experiments were performed to investigate the perception of peripherally presented apparent motion as a function of eccentricity of the stimulus, ambient illumination, sex, stimulus pattern, and angular extent of stimulus presentation. The experimental task for both studies was to judge the direction of apparent motion for a stimulus target lighter than the background and presented on a Braumbach perimeter. The results from Exps. 1 and 2 indicated main effects for subjects and eccentricity. The combined results of Exps. 1 and 2 indicated main effects for eccentricity and angular separation of the apparent motion, however, the interaction between the two was not significant.
