  • Title: Asymmetries in the spatial localization of transformed targets.
    Author: Chua R, Carson RG, Goodman D, Elliott D.
    Journal: Brain Cogn; 1992 Nov; 20(2):227-35. PubMed ID: 1449755.
    Abstract:
    This study was designed to examine the contribution of the right cerebral hemisphere in the spatial localization of visual targets for manual aiming. Visual targets were briefly presented to the right and left fields and subjects were required to point either to the target location, or a "mirror" image of the target location with their right or left index finger. Whereas reaction times were faster for left-hand pointing than for right-hand pointing, there was no differential effect of the mirror image transformation. This suggests that left-hand reaction time advantages are more related to right hemisphere involvement in the spatial parameterization of the movement than spatial localization of the target.
