title: Pursuit eye movements in psychopathology: effects of target characteristics.
abstract: Tests of smooth pursuit eye movements using two types of targets, at three different frequencies, with two types of superimposed cognitive tasks were performed by 16 manic-depressive patients, 16 schizophrenic patients, and 14 normal subjects. The results showed that patients track more poorly than normals at all frequencies with either a real pendulum or an electronically driven target. Tracking efficiency of all subjects is improved by both superimposed cognitive tasks. Differences between patients and nonpatients exist under all experimental conditions.
