To investigate effects of auditory information in perceiving object size, audio-visual stimuli where motion pictures simulating a ball to bound on a ground is combined with a sound of ball smashing were presented to human participants. The task was to evaluate the "visual" size of the perceived object. Although the task was visual and the experimental situation contained more visual informations than auditory informations, it was clearly observed that the perceptual evaluation was systematically influenced by the scaling of the auditory stimuli.
