- Regular gamblers will produce more irrational verbalisations than non regular gamblers.
- Rgs will report themselves to be more skill orientated than nrgs on objective measures of skill.
- Participants in the thinking aloud condition would take longer to do the task compared to those who didn’t think aloud.

Research method to griffiths?
Quasi- field experiment
Griffiths procedure?
Give £3 to gamble with on the fruit skill game, 3 players objected as they weren’t familiar with this game. Rgs changed machines at least 3 times, players were asked to stay on each machine for at least 60 gambles and they could keep £3 if they won it back! Thinking aloud condition, given lapel microphones and told to say everything that went through their head!
Griffiths results?
Rgs had a higher playing rate of 8 gambles per minute, rgs who thought aloud had a lower win rate. Verbalisations analysed through a codified system and both groups used rational rather than irrational verbalisations. All hypotheses supported other than 2
Griffiths conclusion?
Rgs have different cognitive thought processes than nrgs.
