Eye movement frequencies versus speed discrimination thresholds at 300 msec stimulus condition, where schizophrenia patients showed impaired speed discrimination thresholds. There were no significant correlations in schizophrenia patients in the 10.0°/sec or 18.7°/sec test speeds (first stimulus). There were negative correlations in the control subjects, significant at the 10.0°/sec test speed, suggesting that more eye movements were associated with better speed discrimination thresholds in the control subjects but not in the patients. There were no significant correlations in the reference speeds (second stimulus) in either group, even though there were more eye movements here.
