 Abstract: Both physical and physiological transmission times can differ between audition and vision. Under certain conditions, the brain reduces perceived asynchrony by adapting to this temporal discrepancy. In two experiments we investigated whether this recalibration is specific to auditory and visual stimuli, or whether other modality combinations (audiotactile, visuotactile) are affected, as well. We presented asynchronous audiovisual signals, with either auditory leading or visual leading. Then, using temporal order judgments we measured observers point of subjective simultaneity for three modality combinations. Results indicate an adjustment of perceived simultaneity for the audiovisual and the visuotactile modality pairs. We conclude that audiovisual adaptation is the result of a change of processing latencies of visual events. In a second experiment, we corroborate this finding. We demonstrate that reaction times to visual signals, but not to tactile or auditory signals, change as a result of audiovisual recalibration.
