title: Left hemispheric advantage for a visuopatial-dichaptic matching task.
abstract: Twenty right handed, female subjects performed a visuospatial-dichaptic matching task which required them to view a single shape for a brief period of time while palpating two shapes, one in each hand. There was an identification and reaction time advantage for right hand responses, which allowed the inference of a left hemispheric advantage for this particular matching task. These results are discussed in reference to factors that may modify the typical right hemispheric superiority for the processing of spatial information, i.e., motor feedback, concurrent memory load, and the differential use of spatial cues.
