abstract：:How are multiple, multi-sensory stimuli combined for use in segmenting spatio-temporal events? For an answer, we measured the effect of various auditory or visual stimuli, in isolation or in combination, on a bistable percept of visual motion ("bouncing" vs. "streaming"). To minimize individual differences, the physic...
