Abnormal negative feedback processing in first episode schizophrenia: evidence from an oculomotor rule switching task

摘要

BackgroundPrevious studies have shown that patients with schizophrenia are impaired on executive tasks where positive and negative feedbacks are used to update task rules or switch attention. However, research to date using saccadic tasks has not revealed clear deficits in task switching in these patients. The present study used an oculomotor “rule switching” task to investigate the use of negative feedback when switching between task rules in people with schizophrenia.
