The present project aims at investigating the role of attention on visual-auditory integration, and the possible mediating role of time perception. Based on our previous studies on visual spatial perception and attention, we extend it to visual-auditory interaction and to temporal domain. Past studies that found no role of attention on visual-auditory interaction may have confounded the factors of top-down influence, the range of affordance of each modality to the other one, and inadequate manipulation of attention. The purpose of this three-year project is to tease apart possible factors involved, and to use behavioral and brain imaging techniques in three series of studies to examine the relationship between visual-auditory integration, attention, and time perception.
