• Eysenck and Eysenck compared 2070 prisoners scores on the EPQ with 2422 controls
• on measures of extraversion, neuroticism and psychoticism prisoners recorded higher than average scores than controls
• Farrington et al conducted a meta analysis of relevant studies and reported that offenders tended to score high on measures of psychoticism but not for extraversion and neuroticism
• inconsistent evidence of differences on EEG measures between extraverts and introverts
• Moffitt drew a distinction between offending behaviour that only occurs in adolescence and that which continues into adulthood
• personality traits alone are a poor predictor of how long offending behaviour would go on for
• Moffitt considered persistence in offending behaviour to be the result of a reciprocal process between individual personality traits and environmental reactions to those traits
• criminal personality may vary according to culture
• Bartol and Holanchock studied Hispanic and african american offenders in a maximum security prison in New York
• all six groups were less extravert than a non offender control group
• Bartol and Holanchock suggested this was because the sample was from a very different cultural group from that investigated by eysenck
