Abstract
Previously, we reported that upright observers, experiencing real leftward/rightward or forward/backward body motion while viewing orthogonal translating or expanding/contracting optic-flow, perceived self-motion directions intermediate to those specified by visual and vestibular information (Sakurai et al, 2010, Journal of Vision, 10(7): 866). Here we investigate conditions in which observers lay supinely, experiencing real upward/downward or leftward/rightward motion in body coordinates, while viewing orthogonal optic-flow patterns, phase-locked to the swing motion. Optic-flow patterns consisted of leftward/rightward or upward/downward translational or expanding/contracting oscillatory optic-flow. Observers were cued with a sound to indicate their perceived direction of self-motion, via a rod-pointing task. When upward/downward or leftward/rightward body motion was combined with visual leftward/rightward or upward/downward optic-flow, most observers' direction judgments progressively favored the direction specified by vision with increasing amplitude of optic-flow, as in our previous reports, suggesting a weighted combination of visual and vestibular cues in this context. For combinations of body motion with visual expanding/contracting optic-flow, some observers' judgments were vision-only or vestibular-only, suggesting that multimodal integration in this context is an either-or process for these observers. Compared to our previous reports, one possible reason for this weighted combination failure is the discrepancy between body coordinates and gravity coordinates.
