| Abstract(in English) | The threshold for correct identification of temporal order was investigated using the psychophysical method of constant stimuli.Participants were presented with pairs of vibrotactile stimuli delivered to different hands, and made a forced-choice response(left hand-first vs.right hand-first vs.simultaneous)indicating temporal order of stimuli.The results showed that(1)the onset of the first stimulus of a pair of stimuli had to occur approximately 40-50 ms before the second stimulus in order for the two to be perceived as successive;(2)the threshold stimulus onset asynchronies(SOAs)were shorter when the left hand stimulation preceded the right hand one compared to the opposite order of presentation;(3)this left-first advantage was not replicated by a different psychophysical method(PEST)or a manipulation of hernispace with crossed-arms condition.The findings suggest that leftward advantage for the judgment of temporal order is not the result of a right hemisphere specialization for tactile temporal discrimination but that of a hemispatial attentional bias. |
