Summary
Psychopathic traits, characterized by callousness, predict persistent antisocial behavior. Research highlights neurocognitive markers and heritability, suggesting a developmental disorder requiring an interdisciplinary approach.
Area of Science:
- Psychology
- Neuroscience
- Genetics
Background:
- Psychopathy involves antisocial behavior and a callous-unemotional personality.
- Psychopathic personality traits are key to understanding persistent antisocial conduct.
- This review covers cognitive neuroscience and genetic evidence on psychopathy development.
Purpose of the Study:
- To review evidence on psychopathic personality traits.
- To explore developmental trajectories of psychopathy.
- To integrate cognitive neuroscience and genetic findings.
Main Methods:
- Selective review of existing literature.
- Examination of cognitive neuroscience research.
- Discussion of preliminary genetic and twin studies.
Main Results:
- A personality-based approach defines psychopathy with distinct neurocognitive markers.
- These markers, present in children, suggest psychopathy as a developmental disorder.
- Core psychopathic traits show high heritability, with preliminary evidence from twin studies.
Conclusions:
- Psychopathy may be a developmental disorder with neurocognitive underpinnings.
- Callous-unemotional traits link to vulnerability to persistent antisocial conduct.
- An interdisciplinary approach integrating neuroscience and genetics is crucial for understanding psychopathy development.
