Subjects were placed, in complete darkness, and asked to elicit a saccade from a repeatedly flashing stimulus in the center of the visual field to a saccade target located 10 deg to the right of the stimulus. The stimulus produced several phantom flashes basically in the direction of the saccade; they were mislocalized to the saccade target, when the flashing frequency was high (e.g., 500Hz). The stimulus was extinguished near the saccade in time. The subjects reported the position of the finally perceived phantom flash. The results of the two experiments showed that the degree of mislocalization decreasing flashing frequency, but it is not affected by the luminance of each flash or the average luminance of the flashing stimulus. Our previous study suggested that the degree of mislocalization depends on the attended position during the saccade. The results of the present study were discussed related to the attention shift.
