  • Title: Relationship between smooth pursuit eye-tracking and cognitive performance in schizophrenia.
    Author: Friedman L, Kenny JT, Jesberger JA, Choy MM, Meltzer HY.
    Journal: Biol Psychiatry; 1995 Feb 15; 37(4):265-72. PubMed ID: 7711164.
    Abstract:
    The relationship between measures of smooth pursuit and neuropsychological performance was assessed in 20 unmedicated schizophrenics. Eye-tracking measures included gain, catch-up saccade parameters, and rate of saccadic intrusions. Neuropsychological measures included tests generally considered as "frontal": Wisconsin Card Sorting Test (WCST), Consonant Trigram Test (CTT), and Controlled Oral Word Association Test (COWAT). The Digit Symbol Test (DST), which is generally considered to be a measure of global functioning, was also included. Gain and other pursuit measures were significantly correlated with the DST and the COWAT, but were not correlated with the WCST or the CTT.
