Psychopathy is linked to altered attention. This study found distinct brainwave patterns, specifically larger frontocentral negativities (N550), in psychopaths during an auditory task, suggesting paralimbic system dysfunction.

Area of Science:

  • Neuroscience
  • Psychology
  • Forensic Psychology

Background:

  • Psychopathy is characterized by attention and orienting deficits.
  • Neural correlates of these deficits remain underexplored.
  • Understanding these neural systems is crucial for psychopathy research.

Purpose of the Study:

  • To investigate the neural systems underlying attention and orienting in psychopathy.
  • To examine event-related potentials (ERPs) in psychopathic and nonpsychopathic individuals.
  • To explore the relationship between psychopathy and paralimbic system function.

Main Methods:

  • Event-related potentials (ERPs) were recorded from 80 incarcerated men.
  • Participants were classified as psychopathic or nonpsychopathic using the Hare Psychopathy Checklist--Revised.

  • An auditory oddball task was administered to assess attention and orienting.

    • Main Results:

    • Psychopaths exhibited larger frontocentral negativities (N550) when processing targets compared to nonpsychopaths.
    • Psychopaths showed an enlarged N2 component during target detection.
    • A reduced P3 component was observed in psychopaths during target detection.

    Conclusions:

    • The findings support the hypothesis that psychopathy is associated with paralimbic system dysfunction.
    • Observed ERP modulations in psychopaths resemble those seen in individuals with amygdala and temporal lobe damage.
    • These results highlight potential neural underpinnings of attention abnormalities in psychopathy.
