Abstract:
The authors studied the relationship between performance on the Wisconsin Card Sorting Test and on the Trailmaking-B test and measures of smooth pursuit eye movements in 12 patients with chronic schizophrenia and 12 normal volunteers. They found that performance on the Wisconsin Card Sorting Test was significantly correlated with measures of smooth pursuit eye movements in schizophrenic patients but not in normal subjects. Trailmaking-B scores, however, were unrelated to smooth pursuit eye movements in either group.
