Abstract
This study was designed to examine whether normal information processing does engage both hemispheres of the brain regardless of sensory channel (i.e., auditory or visual), and whether an opportunity for dual encoding (verbal and visual) was advantageous for patients with unilateral brain damage. It compared memory for verbal material presented in the visual and auditory modalities among three groups: right hemisphere brain damaged stroke patients (RBD), left hemisphere brain damaged stroke patients (LBD), and neurologically intact control subjects.
Only control and LBD subjects benefited from the visual presentation compared with auditory. Controls did generally better on both modes than either stroke group. These data suggest that normal information processing does engage both hemispheres of the brain, and that the capacity to use visual and verbal encoding aids memory for LBD patients and normal controls, but that RBD patients are impaired in their ability to use visual encoding to enhance their verbal memory.
