Abstract
This paper examines the effect of auditory perception on visual temporal-order judgments by focusing on the spatial congruence of auditory and visual stimuli (i.e., right or left). Visual stimuli were presented successively at short intervals, while auditory stimuli were presented before and after the visual stimuli. In the first experiment, the accuracy of visual temporal-order judgments was enhanced by the presence of auditory stimuli when the visual and auditory stimuli were spatially congruent, but the accuracy was reduced when the visual and auditory stimuli were spatially incongruent. These changes in performance were even observed at a long stimulus onset asynchrony between the auditory and visual stimuli (AV-SOA) of 640 ms. In the second experiment, the auditory stimulus presented before the visual stimuli was found to have a greater influence on performance on the visual temporal-order judgment task than the auditory stimulus presented after the visual stimuli. These results indicate that spatial congruence influences auditory capture within visual temporal-order judgments.
