【 摘 要 】

This study examined self-reported impulsivity and aggression and performance on the stop-signal task in patients with schizophrenia or schizoaffective disorder and healthy volunteers. Compared to controls, patients had higher scores on interview and questionnaire measures of impulsivity and aggression and showed increased stop-signal reaction time and greater response variability. These findings are consistent with a specific impairment in response inhibition in schizophrenia. (C) 2010 Elsevier Ireland Ltd. All rights reserved.
