Abstract
The level of performance in the execution of a tactual-linguistic task was studied in two left-handed populations, one with language lateralized to the left and the other with language lateralized to the right hemisphere, according to Kimura's dichotic digit test.
The results showed that left-handers with speech most likely lateralized to the left hemisphere performed significantly better in the tactual-linguistic task with the left hand, while the ones with speech probably lateralized to the right hemisphere, did better with the right hand.
The data suggest that integration of functions asymmetrically represented is facilitated by their differential lateralization.
