title: Variation of saccadic suppression with target eccentricity.
abstract: Two LEDs separated by 24 degrees from each other were employed as saccadic fixation sources located on a circle about the centre of the saccade path. Either horizontal, vertical or oblique saccade paths were used and a brief test flash was presented at one of five retinal eccentricities during each saccade. The percentage of detected flashes was measured as a function of the location of the test stimulus and of its time delay with respect to the onset of the saccade. The results suggest that saccadic suppression is maximal at the fovea and is significantly decreased as retinal eccentricity increases.
