| Abstract(in English) | Fingers of both hands (except thumbs) are laid with palm-side down and alternatively for left and right so that tips are only visible by subject's eyes. Tactile (weak vibration) and/or visual (LED) stimuli are given to each finger at a time. Discrimination of stimulated finger is done either by moving a finger or by speaking which finger, and both by these reactions. In reaction by movement, additional visual stimulus decreased ambiguity in tactile perception in effect of shortening reaction time. Under single stimulus by tactile, ipsi-lateral fault reaction was dominant in frequency since reactions are done primarily by somatosensory information. On the other hand, under combined stimulus, contralateral fault reaction was dominant implying visual dominance. The same reaction scheme was observed for reaction by movement instantly succeeded to language reaction. By contrast, in reaction by language, visual sensory information did not affect reaction time nor frequency of fault reaction (except easily discernible little fingers placed at spatial edges) . These result suggests that language reaction is based on body-image compatible to egocentric perception of space and on somatosensory perception and visual information spontaneously constructed upon the body-image. |
