A 50-year-old man presented a rare morphological constellation: a left-sided varicocele (stage 3) and a vascular rich Sertoli cell tumor.
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… (More)
This study investigated the perception of the direction of peripheral apparent motion as a function of stimulus location in the peripheral visual field, stimulus contrast, and the direction of the apparent motion. Results indicated that each of these independent variables was significant as a main effect while the interactions were not.
