The　effects　of　attention　on　audiovisual　integration　at　an　incongruent　location　was　investigated　using　behavioral　measures　in　humans.　A　stream　of　unimodal　visual　(V),　unimodal　auditory　(A),　spatially　congruent　bimodal　audiovisual　(AV-Con)　and　spatially　incongruent　bimodal　audiovisual　(AV-Inc)　stimuli　were　randomly　presented　to　the　left　or　right　side;　subjects　covertly　attended　to　all　stimuli　on　one　side　(left　or　right)　and　promptly　responded　to　all　target　stimuli　on　that　side.　The　results　showed　that　responses　to　the　bimodal　target　stimuli　were　faster　and　more　accurate　than　those　to　unimodal　visual　or　atuditory　target　stimuli　when　audiovisual　stimuli　were　presented　on　spatially　congruent　location.　When　audiovisual　stimuli　were　presented　on　spatially　incongruent　location,　responses　to　visual　stimuli　that　were　accompanied　by　simultaneous　task-relevant,　but　spatially　incongruent　auditory　stimuli　were　facilitated.　However　responses　to　auditory　stimuli　that　were　accompanied　by　simultaneous　task-relevant,　but　spatially　incongruent　visual　stimuli　were　not　facilitated.　The　results　suggested　that　vision　was　high　preferential　processing　when　auditory　and　visual　information　were　simultaneously　presented　on　spatially　incongruent　location.　©　2010　IEEE.
