    • SUPPORTING RE (ILLUSION OF CONTROL)
      } Griffiths (94) - fruit machines > regular and non-gamblers
      used introspection - say what they were thinking and content analysis
      exp - more irrational verbalisations (14%) than non-g (2.5%)
      gamblers - faulty thinking in relation to gambling
      ev gives validity to exp - specifically RO self serving bias and illusion of control
    • SUPPORTING RE (ATTENTIONAL BIAS)
      } Knight et al (2017) - compared 25 heavy drinkers to 25 moderate / light drinkers on attentional test with pics relating to alcohol and not
      quasi = naturally changing IV
      heavy - quicker identifying alcohol related stimuli + slower and made more mistakes with non alc stimuli
      measured response time to change in objects and no. mistakes
      provide evidence for exp and gives val
    • REDUCTIONIST - TOO SIMPLISTIC
      e.g. AB - may exp A's tendency to be drawn to A related clues > doesn't explain why they became A / what causes cognitive biases
      sug CB play role but not sole exp > ignores other influences
      EXT - Volkow - AB changes PFC > could cause AB (bio - better)
    • CONCLUSION
      • useful to consider thought processes involved in AB > challenged in CBT - useful exp
      • exp tested + measured in lab > more scientific than others
      • exp - provided description of why symptoms occur > fail to account for cause of faulty thought processes
