Aim: This study set out to examine three factors in the cognitive psychology of gambling. Firstly, Griffiths examined whether the skill involved in fruit machine gambling is in fact ‘actual’ or ‘perceived’, by comparing the success of regular and non regular gamblers. Secondly this study examined the cognitive activities of regular and non-regular fruit machine gamblers while gambling using the ‘thinking aloud method’. Thirdly subjective measures of skill perception in regular and non-regular fruit machine gamblers were examined using a post-experimental semi-structured interview.
Hypotheses: The aim of this study was to investigate cognitive bias involved in gambling behaviour. There were three main hypotheses:
- 1. There would be no difference between regular and non regular fruit machine gamblers on objective measures of skill.
- 2. Regular gamblers would produce more irrational verbalisations than non-regular gamblers.
- 3. Regular gamblers would be more skill orientated than non-regular gamblers on subjective measures of self-report
An additional hyothesis was added,which was:
- 4. A further hypothesis was also added that thinking aloud participants would take longer to complete the task than non-thinking aloud participants.
