Schematic illustrations of the stimuli, conditions, and results of Section “Experiment 6.” (A) Stimuli and conditions. We presented the target and one of the inducers at the center of the display. In each trial, after 400 ms of the target presentation, the inducer was presented for 80 ms. Next, the target was temporally offset for 80 ms. The target subsequently reappeared, and its horizontal position was displaced either 0.03°, 0.06°, 0.12°, or 0.24° in the left or right direction. An inducer was then presented. While the inducer was presented at the same position as the first inducer in the No-motion condition, the inducer’s position was shifted toward the left or right in the Motion condition. (B) We plotted the proportion at which the perceived direction of the target was consistent with the physical displacements in each motion condition. Positive values of the target’s displacements indicate that the displacements were consistent with the AM direction in the Motion condition. We then estimated the point of subjective equality. The PSE shifted in the direction consistent with the AM so that the target displacements tended to be perceived to be opposite the AM direction in the Motion condition. Error bars denote standard errors of the mean (N = 4).
