Differential Impairment of Patients with Right Versus Left Hemisphere Lesions on the Ruff-Light Trail Learning Test

The Ruff-Light Trail Learning Test (RULIT) was developed as a neuropsychological measure of visuospatial learning and memory. RULIT scores of patients with right hemisphere and left hemisphere damage, as well as matched controls were compared. Right hemisphere lesion patients scored significantly lower on RULIT measures than did left hemisphere lesion patients and controls. The performance of left hemisphere lesion patients and controls did not differ significantly on RULIT measures. Adequate clinical hit rates, sensitivity and specificity in identifying right hemisphere damaged patients were demonstrated.
