Right hand superiority in serial recall of tactile stimuli.
The fingertips of right and left hand of normal subjects (right-handed male) were stimulated at random. After intervals of 0.3, 1.0, 3.0 and 6.0 seconds, an acoustic or tactile signal set off the response of the subject. The response was the ordered reproduction of the tactile sequence given to the subject. The results show a greater efficiency of right hand, a better recall of the first serial positions and of the last one but no difference depending on whether the recall signal is acoustic or tactile. The results are discussed and new hypotheses are formulated.
