  • Title: A longitudinal analysis of eye tracking dysfunction and attention in recent-onset schizophrenia.
    Author: Yee CM, Nuechterlein KH, Dawson ME.
    Journal: Psychophysiology; 1998 Jul; 35(4):443-51. PubMed ID: 9643059.
    Abstract:
    The effect of an attentional manipulation on eye tracking dysfunction (ETD) in the early stages of schizophrenia was examined in 34 recent-onset schizophrenic patients and 24 demographically matched normal subjects over a 1-year period. An attentional enhancement manipulation improved eye tracking performance of recent-onset schizophrenic patients more than that of normal subjects. Eye tracking level also was moderately stable for both groups over the course of 1 year. The possible role of attentional allocation in ETD highlights the need for further examination of the interface between attentional and eye tracking measures of vulnerability to schizophrenia.
