- - - - drive
      - fun - seeking
      - reward responsiveness
- - - - negative: feel bad therefore do bad
      - positive: feel good therefore do bad
- - - - Kendler et al., 2003
        
        model of heritability
        
        very strong genetic risk correlation between licit and illicit (.82)
        
        relations between substance dependance and heritable risk (higher for illicit)
      - changes in heritability across time
      - overlap in vulnerability across substances
- - - - behaviour inhibition
      - escape punishment
      - neg emotion
- - - - general tendancies
      - specific situs
- - - - extraversion
      - reward reactivity (sensitivity)
    - - psychoticism
      - low conscientiousness
      - impulsivity
    - - behavioural inhibition
      - trait anxiety
      - neuroticism

      - BAS reward basically zero...
      - Franken 2006: compared a group receiving alcoholism treatment and a group seeking treatment for heroin / cocaine additions with controls
        
        alcoholism
        
        mid drive and fun seeking
        
        controls
        
        lowest d and f s
        
        drug addicts
        
        high drive and fun seeking
      - some evidence to suggest that both impulsivity and reward sensitivity traits relate to increased use of substances and risk for problem usage with distinctions across illicit and licit
- - - - impulsiveness
      - further sub misuse
      - initial sub misuse
      - reward sen
