| Research Abstract |
This study purposed to demonstrate integration of audio-visual information at unconscious level in spatial perception. For this purpose, we established empirical procedures to present auditory stimulus unconsciously at first. Then we examined effects of unconscious visual stimuli on the subsequent auditory judgment, and vice versa. The result showed the significant effect of visual stimulus in two-dimensional localization. The effect was less obvious in two-dimensional motion direction, and disappeared in three-dimensional perception. Effect of auditory stimulus was generally subtle. So these indicating unconscious interaction, suggest two critical factors of (i) the integrated representation of audio and visual signals and (ii) the spatial resolution in vision and audition.
