Sinusoidal Smooth Pursuit Eye Tracking at Different Stimulus Frequencies: Position Error and Velocity Error Before Catch-Up Saccades in Schizophrenia and in Major Depressive Disorder

Abstract

Eye tracking dysfunction in schizophrenia can be described as follows with regard to position error and velocity error: On the one hand, there is an increased position error tolerance largely independent of stimulus frequency, possibly due to an impairment of processing localization information. On the other hand, velocity processing is more severely impaired by an increase in stimulus frequency.
