Research Abstract	We may have potentially two temporal references for the simultaneity judgment of inter-limb movement, the afferent sensory feedback and the efferent information of motor output. The present study examined 1) whether the temporal simultaneity of bimanual movement is judged with reference to the afferent or the efferent information, and 2) tested a hypothesis that the simultaneity is judged not only by primary reference, but secondary other source involves as well. The results suggest that, 1) the simultaneity judgment between two hand movements may be achieved by mainly referring to the efferent component of the movement, 2) the afferent input may regulate the temporal judgment for bimanual movement.
