Much　knowledge　has　been　gained　about　how　the　brain　is　activated　on　audiovisual　interaction.　However,　few　data　was　acquired　about　the　relationship　between　audiovisual　interaction　and　spatial　locations　of　audiovisual　stimuli.　Here,　we　investigated　the　multisensory　interaction　of　audiovisual　stimuli　presented　on　central　and　peripheral　spatial　locations.　Firstly,　we　determined　the　maximal　eccentricity　of　peripheral　spatial　location　on　where　stimuli　were　presented　which　was　30°.　Second,　the　results　of　audiovisual　interaction　showed　that　the　interaction　of　visual　and　auditory　can　have　dramatic　effects　on　human　perception　and　performance.　Moreover,　this　effect　depended　on　the　spatial　locations　of　presented　audiovisual　stimuli.　©　2009　Springer-Verlag　Berlin　Heidelberg.
