The effects of stimulus eccentricity (central or peripheral) on vection (visually induced self‐motion perception) were investigated using a stimulus combination consisting of a static foreground and a moving background, the depths of which were defined by binocular disparity. By using these stimulus settings, the effect of stimulus eccentricity can be assessed without any artifacts in the perceived depth of the stimulus, which would covary with the stimulus eccentricity. The results of this psychophysical experiment indicated that stimulus eccentricity cannot affect the strength of vection, and that both the central and peripheral stimuli can induce self‐motion perception with equal magnitudes if the stimulus sizes are equalized. The present investigation, which used a controlled stimulus depth condition, clearly negated the idea of the peripheral dominance of vection, which has been accepted for a long time.
