Evaluation

• A: EPQ predictive validity - Dunlop et al. (2012) (E+P)

  OS: Criminal behaviour may be situational - Mischel + Peake (1982) rating 63 students in various situations

  SS: Twin studies support biological basis of E+N - Zuckerman (1987)

  MW: Self Report - social desirability
• Mischel + Peake (1982)

  • asked friends, family + strangers to rate students in various situations
  • found almost no correlation between traits displayed
  • suggests environmental factors may provoke criminal behaviours (e.g. who we're talking to), not solely a result of innate disposition.
• Zuckerman (1987) - N + E

  • for N: +0.52 for MZ, 0.24 for DZ
  • for E: +0.50 and 0.12, respectively
