Error-related processing in adult males with elevated psychopathic traits

Area of Science:

• Neuroscience
• Psychology
• Criminology

Background:

• Psychopathy is a personality disorder linked to increased violent recidivism in incarcerated individuals.
• Cognitive deficits in error processing may underlie poor decision-making and recidivism risk.
• Abnormalities in error processing are hypothesized to involve either error monitoring or posterror processing.

Purpose of the Study:

• To investigate error processing abnormalities in incarcerated males with varying levels of psychopathic traits.
• To differentiate between error-monitoring (ERN/Ne) and posterror processing (Pe) in relation to psychopathy.
• To test the attentional bottleneck theory's prediction of posterror processing deficiencies in high psychopathy.

Main Methods:

• Ninety-three incarcerated males completed a Go/NoGo response inhibition task with electroencephalography (EEG) recording event-related potentials (ERPs).
• Error-monitoring (ERN/Ne) and posterror processing (Pe) were measured using time-domain and principal component analyses.
• Psychopathic traits were assessed using the Hare Psychopathy Checklist-Revised (PCL-R).

Main Results:

• Higher PCL-R Total, Factor 1, and Facet 3 scores were positively correlated with increased Pe amplitude (posterror processing).
• No significant relationship was found between psychopathic traits and ERN/Ne amplitude (error monitoring).
• Results indicate enhanced, not deficient, posterror processing in individuals with elevated psychopathic traits.

Conclusions:

• Findings support the attentional bottleneck theory, suggesting specific posterror processing enhancements in psychopathy.
• Error processing differences, particularly in posterror evaluation, are linked to psychopathic traits.
• Understanding these cognitive mechanisms may aid in developing targeted interventions for psychopathy and reducing recidivism.
