Is eye tracking dysfunction specific to schizophrenia?
Based on eye tracking studies in psychiatric patients, normal controls, and first-degree relatives of patients, Holzman, Proctor, and Levy et al. (1974) state that eye tracking dysfunction (ETD) is specific to schizophrenia and may be a genetic marker of that disorder. A review of numerous subsequent studies, however, suggests that ETD is not specific to schizophrenia, but is restricted to func...
متن کاملManual tracking enhances smooth pursuit eye movements.
Previous studies have reported that concurrent manual tracking enhances smooth pursuit eye movements only when tracking a self-driven or a predictable moving target. Here, we used a control-theoretic approach to examine whether concurrent manual tracking enhances smooth pursuit of an unpredictable moving target. In the eye-hand tracking condition, participants used their eyes to track a Gaussia...

متن کاملEfference copy failure during smooth pursuit eye movements in schizophrenia.
Abnormal smooth pursuit eye movements in patients with schizophrenia are often considered a consequence of impaired motion perception. Here we used a novel motion prediction task to assess the effects of abnormal pursuit on perception in human patients. Schizophrenia patients (n = 15) and healthy controls (n = 16) judged whether a briefly presented moving target ("ball") would hit/miss a statio...
متن کاملSmooth pursuit eye movements to isoluminant targets.
At slow speeds, chromatic isoluminant stimuli are perceived to move much slower than comparable luminance stimuli. We investigated whether smooth pursuit eye movements to isoluminant stimuli show an analogous slowing. Beside pursuit speed and latency, we studied speed judgments to the same stimuli during fixation and pursuit. Stimuli were either large sine wave gratings or small Gaussians blobs...
