In this study, we investigated whether the preceding sound or light point (cue stimulus) biases perceived directions of moving sound (target stimulus) to evaluate the effect of cross-modal attention on the spatial information processing in the human auditory system. First, a narrow band noise, as an auditory cue, was presented in various cue-lead time and at various place (auditory cue experiment). Thejudgment of the target-motion direction was biased when a cue was presented in the opposite direction to that of a target motion and in shorter cue-lead time. The effect of the distance between a cue and a target was not significant. Next, a light point emitted form LED, as a visual cue, was presented in various cue-lead time and at various place (visual cue experiment). Thejudgment of the target-motion direction was biased when a cue was presented in the opposite direction to that of a target motion. The effect of cue-lead time and distance between a cue and a target was not significant. These results suggest that modality-nonspecific attention might affect on spatial-information processing (judgment of movement direction) in the human auditory system.
