Response-locked component of error monitoring in psychopathy: A systematic review and meta-analysis of error-related negativity/positivity

Evidence suggests that psychopathic individuals display difficulties to adapt their behavior in accordance with the demands of environment and show altered performance monitoring. Studies investigating error-related negativity (ERN) error-positivity (Pe) as electrophysiological markers error monitoring reported contradictory results for this population. To explain these discrepancies, we hypothesized psychopathy dimensions influence outcomes. We predicted impulsive-antisocial features would abnormal ERN compared interpersonal-affective features. A systematic review meta-analysis studies Pe components were conducted. factorial analysis was undertaken investigate role on Pe. Compared controls, (n = 940) showed a reduced amplitude. The indicates dissociation regarding construct psychopathy. models related specifically dimension displayed normal component efficient error-monitoring, while marked decreased
