Effects of spatial location on bisensory audiovisual integration in horizontal meridian

Crossmodal spatial integration between auditory and visual stimuli is a common phenomenon in space perception. In the present study, the effects of spatial location on bisensory audiovisual integration in horizontal meridian were investigated. The behavior results of audiovisual integration were compared at -30°, 0° and 30° on horizontal direction. Our results showed that responses to audiovisual stimuli presented at a center location (0°) were faster and more accurate than those presented at peripheral locations (±30°). The results suggest that bimodal audiovisual integration depends on the spatial location of audiovisual stimuli.
