Figure 2.

Schematic illustrations of stimuli and results of Section “Experiment 1B.” (A) Stimuli. We manipulated the vertical distance of the target as 0°, 2°, 4°, or 8° from AM stimuli, which were presented at a fixed position (2° of eccentricity from the fixation point). (B) Results. Proportion of illusory motion perception perceived for the target increased with the increment of the target’s eccentricity. Error bars denote standard errors of the mean (N = 4).
