Abstract
Currently, relatively little is known about what drives the choice of limb for goal-oriented reaching. Traditionally, the explanation has been tied pr edominately to motor dominance as manifested in handedness. This article of fers data and an argument suggesting that handedness can be modified by att entional (spatial) information. Although motor dominance may be the control ling factor in the programming and execution of reaching movements at the m idline and hemispace ipsilateral (same side) to the dominant limb, attentio nal information alters the programming of movements in what would be contra lateral space. The general trend of behavior is characterized by reaching o n the same side as the stimulus, in ipsilateral fashion, a phenomenon expla ined by kinesthetic efficiency and hemispheric bias.
