When the hand is stimulated during hand movements, humans can localize the stimulated position even without visual guidance. This is because the sensorimotor system integrates internal information of the hand's location and perceived temporal information of the stimulus. It is reported that when transient tactile stimulation was presented before, during or after hand movements, the stimulus was systematically mislocalized. The mislocalization was interpreted as a result of mismatch between internal information and the physical location of the hand. However, typical environments exhibit a high degree of spatiotemporal coherence, and a different spatial localization strategy may be more adaptive to the continuous case. Here, we examine the time courses of localization for both transient and intransient vibration stimuli, to gain further insight into the spatial localization mechanism of the hand.
