Abstract
We examined the effect of auditory perception on visual temporal-order judgment by investigating the spatial congruence between auditory and visual stimuli (i.e., right or left). Visual stimuli were presented successively at a short interval, and auditory stimuli were presented before and after them. A pair of speakers was used for auditory stimuli in order to represent the actual environment more properly than a preceding research of ours in which a headset was used (Hongoh & Kita, 2005). In the first experiment, the accuracy of visual temporal-order judgment was enhanced in the congruent condition that two visual stimuli and two auditory stimuli were presented from the right to the left, and reduced in the incongruent condition that two visual stimuli were presented from the left to the right and two auditory stimuli were presented from the right to the left; and vice versa. In the second experiment, the auditory stimulus presented before the visual stimuli was shown to be more effective. These results replicated the preceding research except a slight difference of weaker enhancements in the congruent condition compared with the preceding research, and consequently confirmed the important role of spatial congruence in the auditory capture of visual temporal-order judgment.
