Intra- and interhemispheric integration of tactual and visual spatial information

The subjects performed a tactuospatial-visuospatial matching task in which stimuli were presented either to the same sensory field or to opposite fields. Although there was an overall left-side/right-hemisphere advantage for this task, intrahemispheric matching was superior to interhemispheric matching. The results of the study provide evidence against a strong model of unilateral specialization for spatial processing.
