Abstract des Autors

Two experiments investigated motor control abilities of left- and right-handed fencers in the preparation and on-line control of reaching movements. The aim of the study was to assess the statistical over-representations of left-handers for sword and foil and right-handers for the sabre. Experiment one demonstrated that the right hemisphere/left hand was more efficient for the preparation of reaching movements, whatever subjects' handedness. On the contrary, experiment two demonstrated that the left hemisphere/right hand was more efficient for the on-line control of ongoing reaching movements, independently of handedness. Taken together, these results demonstrated the independence between hemispheric asymmetries for sensori-motor processing and handedness, and explained the advantages linked to the hand used in fencing.
