Abstract

It has been shown that the space location of a single flash presented right before saccade onset was often perceived to be shifted toward the saccade target. The closer to the saccade onset, the bigger the mislocalization error. If two flashes were presented sequentially before saccade onset, would the localization error of the second flash be larger than the first flash? Two flashes above and below the fixation were presented sequentially to the same eye with an ISI of 50ms. Subject's task was to use a probe to set the perceived position of each flash. Results indicated that the first flash was perceived to be shifted more than the first flash if the second flash were presented 15ms or less before saccade onset, and the opposite when the second flash were presented more than 15ms before saccade onset. With unequal luminance condition, the lower luminance flash were perceived to be shifted more than the high luminance flash.(supported by NSF grant BCS-0715076)
