RELATIONSHIP BETWEEN SMOOTH-PURSUIT EYE-TRACKING AND COGNITIVE PERFORMANCE IN SCHIZOPHRENIA

The relationship between measures of smooth pursuit and neuropsycholog ical performance was assessed in 20 unmedicated schizophrenics. Eye-tr acking measures included gain, catch-up saccade parameters, and rate o f saccadic intrusions. Neuropsychological measures included tests gene rally considered as ''frontal'': Wisconsin Card Sorting Test (WCST), C onsonant Trigram Test (CTT), and Controlled Oral Word Association Test (COWAT). The Digit Symbol Test (DST), which is generally considered t o be a measure of global functioning, was also included. Gain and othe r pursuit measures were significantly correlated with the DST and the COWAT, but were not correlated with the WCST or the CTT.
