an individual who scores highly on measures of extraversion, neuroticism and psychoticism and cannot easily be conditioned, is cold and unfeeling, and is likely to engage in offending behaviour
personality theory -
Eysenck (1947) proposed behaviour could be represented along 2 dimensions: introversion-extraversion (E) + neuroticism-stability (N)
2 dimension combine to form a variety of personality characteristics or traits
later added 3rd dimension: psychoticism-socialbility (P)
biological basis -
Eysenck - personality traits are biological in origin and come about through type of nervous system we inherit
extraverts - under active nervous system - constantly seek excitement, stimulation and are likely to engage in risk-taking - don't condition easily so don't learn from miskakes
neurotic - high level of reactivity in SNS - respond quickly to situations of threat - nervous, jumpy and overanxious - unpredictable behaviour
psychotic - higher levels of testosterone - emotional and prone to aggression
the criminal personality type -
neurotic-extravert-psychotic
neurotics are unstable and prone to overreact to situations of threat
extraverts seek more arousal and thus engage in dangerous activities
psychotics are aggressive and lack empathy
role of socialisation -
Eysenck's theory - personality linked to offending behaviour via socialisation processes
saw offending behaviour as developmentally immature in that it is selfish and concerned with immediate gratification
process of socialisation is one in which children are taught to become more able to delay gratification and more socially oriented
people with high E and N scores had nervous systems that made them difficult to condition - less likely to learn anxiety responses to antisocial impulses - more likely to act antisocial
measuring the criminal personality -
Eysenck personality questionnaire (EPQ) - form of psychological test
locates respondents along the E, N and P dimensions to determine their personality type
measurement of personality was a very important part of Eysenck's theory because it enabled him to conduct research relating personality variables to other behaviours - such as criminality
