Multisensory integration impacts coordination

Behavioral benefits have been recently evidenced via multisensory integration process. Reaction times, detection or synchronization performances could be made more efficient by a bimodal stimulation than by its unimodal components. We questioned about the generalization of such results on a more challenging behavioral task. We used a well-known bimanual coordination task in which participants have to synchronize with audio, tactile or audio-tactile metronomes. Results show that according to the intrinsic parameters of the metronome, audio-tactile events could lead to higher coordination performance scores than its corresponding unimodal components.
