We often associate moving objects and changing pitch, e.g., falling stones with descending, and launching rockets with ascending pitch, even when these sounds do not happen in the real-world. The reason for this is unknown. Here we report an illusion in which auditory stimuli with no apparent spatial and motion information [[1–3]] alter human visual motion perception. Subjects made a two alternative forced choice (upward (Vup) or downward (Vdown) visual motion perception) while presented with two superimposed, oppositely moving gratings (experiment 1), accompanied by either an ascending or a descending pitch of pure tone, or broad-band noise (Figure 1A). Gratings with ambiguous motion accompanied by ascending pitch were more likely to be perceived as an upward motion, those accompanied by descending pitch as a downward motion, whereas noise caused no directional bias.
