  • Title: Posture and target location effects on manual preference.
    Author: Westwood DA, Roy EA, Bryden PJ.
    Journal: Brain Cogn; 2000; 43(1-3):421-5. PubMed ID: 10857739.
    Abstract:
    Twenty-nine right-handed participants made unimanual movements to 5 target locations while standing and while balancing on a rocker platform. Manual preference was affected by target location (p < .001; manual preference tended to be concordant with target hemispace) and posture (p < .05; responses from the rocker platform were associated with a lower level of right-hand responding). A location by posture interaction (p < .05) indicated that the effect of posture was present only for targets in left hemispace; the right hand was used less frequently in the rocker condition than simple standing. Manual preference is viewed as a process of response selection motivated by an effort to minimize neural processing and mechanical costs.
