Figure 1. Visual and auditory stimuli used in Experiment 1.

(A) Visual stimuli (white bars) were presented with the various eccentricities from a fixation point. (B) Auditory stimuli (white noise bursts) were presented as alternating or to be fixed at one side of both the ears, and no sound was also presented. (C) A visual stimulus was presented six times, synchronized with an auditory stimulus. The participants' task was to report whether or not they perceived visual motion.
