To compare patterns of lateralized cognitive and neuropsychological functioning between patients with schizophrenia, affective disorders, and healthy controls.
Administered an aphasia screening test to evaluate cognitive functioning in schizophrenic patients (N=22), affective disorder patients (N=105), and age-matched normal controls (N=99).
Assessed potential confounding variables, including age, patient sex, current drug treatment, prior neuroleptic exposure, and illness severity.
Schizophrenic patients exhibited higher total error rates and specifically more dominant temporal/temporoparietal errors than patients with affective disorders.
Both psychiatric cohorts demonstrated higher error rates than normal controls, with group differences persisting independently of demographic factors, illness severity, or medication history.
