Evoked potentials and psychopathy: a commentary on Raine
1Department of Psychological Medicine, University of Otago, New Zealand.
Summary
This review critiques Raine's (1989) evoked potentials and psychopathy model, finding conceptual and empirical flaws. An alternative maturational deficit and cognitive appraisal model is proposed for understanding psychopathy.
Area of Science:
- Neuroscience
- Psychology
- Criminology
Background:
- Critically reviews Raine's (1989) model linking evoked potentials to psychopathy.
- Identifies conceptual limitations in defining psychopathy and empirical weaknesses in the sensation-seeking model.
- Highlights Raine's model's neglect of stimulus modality differences and key psychopathic traits.
Discussion:
- Proposes an alternative framework viewing psychopathy as a maturational deficit in socially deviant behavior.
- Suggests deficits in cognitive appraisal processes underlie the personality deviation aspect of psychopathy.
- Integrates pathological sensation-seeking with deficits in moral reasoning and coping mechanisms.
Key Insights:
- Raine's evoked potential model of psychopathy lacks conceptual and empirical rigor.
- An alternative model integrating maturational deficits and cognitive appraisal offers a more comprehensive understanding.
- Psychopathy encompasses social deviance, personality deviations, sensation-seeking, and impaired moral reasoning.
Outlook:
- Further research is needed to validate the proposed maturational deficit and cognitive appraisal model.
- Investigating the role of stimulus modality in evoked potential studies of psychopathy is recommended.
- This revised approach may enhance diagnostic and therapeutic strategies for psychopathy.

01:37Reason and Intuition
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...
01:27Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...

01:27Psychodynamic Perspectives on Personality
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.

01:29Personality Theory by Eysenck and Eysenck
Hans and Sybil Eysenck developed a widely recognized theory of personality, which emphasizes the role of temperament and genetically based differences in shaping individual traits. Their theory posits that biological factors primarily determine personality and can be understood through two main dimensions: extroversion/introversion and neuroticism/stability.
In the extroversion/introversion dimension, highly extroverted people are sociable, outgoing, and easily connect with others. In contrast,...

01:24Antisocial Personality Disorder
Antisocial personality disorder is a chronic mental health condition characterized by persistent patterns of disregard for the rights and well-being of others. Individuals with antisocial personality disorder exhibit behaviors that include deceitfulness, impulsivity, irresponsibility, aggression, and a profound lack of empathy. These traits often manifest early in life and persist into adulthood, leading to significant personal, social, and legal consequences.

01:29Dark Triad and Person Perception
Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et al. (2014) explored...
