Physically stationary observer perceives illusory self motion in the direction opposite to that of large-field visual motion (visually induced self motion; vection). It is known that visual motions in large region, retinal periphery, and in far depth affect the self-motion perception. We introduced the oppenent-motion stimuli without any difference in size, eccentricity, or depth, in order to see the effect of voluntary attention on self motion. In results, the vection was perceived mainly in the direction opposite to that of non-attended motion (i.e., in the same direction as that of attended motion). Thus, the non-attended visual motion dominated the visually induced self motion. Since retinal-periphery, far-depth, and non-attended motions were generally perceived as 'ground' in the ecological environment, these results suggest 'ground' rather than 'figure' determines the direction of vection.
