Smooth pursuit eye movements (SPEM) and neuropsychological performance were examined in a sample of 29 drug‐treated schizophrenic patients and 22 healthy controls. Patients had impairment in SPEM as well as in a wide range of neuropsychological tests (Wechsler Adult Intelligence Scale, Wisconsin Card Sorting Test. Finger Tapping, Reaction time, Selective attention, Trail‐Making and Simultaneous Capacity). Performance indices were more affected than strategy‐executive indices. Drug type (clozapine vs typical) and dose (chlorpromazine units) were not related to neuropsychological impairment among the patients. Indices from the whole range of tests accurately predicted a subjects’ group identity (patient vs control). Impaired SPEM was predicted more accurately by tests assessing frontal functions. Seven patients, all men, had only marginal neuropsychological impairments.
