Previous research has conflictingly reported the effects of motion upon numerical cognition. Herewith, we investigated separately the effects that changes solely in the perceptual state of ‘self’ during either visual or vestibular mediated motion, have upon numerical magnitude allocation. In the visual condition, we compared magnitude allocation during the perceptual states of either visual- world or self-motion, whereas during the vestibular motion experiment, we compared differences in magnitude allocation during either perceived versus subliminal angular rotations. Critically, given that eye movements' can influence numerical mechanisms,confounding results of previous studies, we ensured that there was no difference in the eye movements elicited between the different perceptual conditions. Our results demonstrate that numerical magnitude allocation can be differentially modulated by the perceptual state of self during visual but not vestibular mediated motion.
