  • Eysenck’s theory of the criminal personality
    • proposed that behaviour is represented along two (later three) dimensions
      • Neuroticism/ stability
      • Introversion/ extroversion
      • (Later) psychoticism
    • The biological basis of personality
      • Neurotics have anxious traits and are difficult to predict.
      • Extroverts have under active nervous systems and thus seek risky and stimulating behaviours.
    • The criminal personality
      • The most likely individual to offend has high levels of neuroticism and extroversion (and later high psychoticism)
    • Socialisation
      • The development of the criminal personality is through socialisation. Those with high E and N scores are harder to condition and so dont respond to punishment and impulse in the same way causing criminal behaviour
    • Measuring the criminal personality
      • Use of the Eysenck Personality Inventory (EPI) which has items that relate to each I/E, N/S and P scores which determine how much of each an individual is.
  • Evaluating Eysenck’s theory
    • Strengths
      • Evidence from Eysenck and Eysenck found that prisoners had higher N and E scores that
    • Weaknesses
      • Criticised because not all high E and N people offend, and not all criminals are high N and E.
      • Cultural bias as it is based on a white sample and does not account for personality differences in African Americans and Hispanic people
      • biologically deterministic as it suggests that criminal personality is due to poor nervous system etc
      • Personality cannot be reduced to just a simple score and a range of factors contribute to personality such as situation, emotion and people
