Audiovisual Time-Flow Experiment Data

In this experiment we introduce the Audiovisual Time-Flow Illusion, a novel illusion whereby regularly-paced visual speech samples are perceived as "pausing" or "skipping" when they are presented with congruent auditory counterparts that contain brief inserted or removed portions (pausing and skipping, respectively). When stimulus manipulation is reversed so that the visual components contain brief inserted or removed portions while the auditory components are regularly-paced, the illusion is not perceived. Our data suggest that visual perception continually realigns its pace with that of the auditory modality, suggesting that the auditory modality sets the pace, or tempo, of the visual modality.
