Grifiths – Individual Differences


What is addiction?

EUPHORIA - a "buzz" or "high"

Withdrawal - Negative side-effects going without - anxiety, nausea, depression

TOLERANCE: Bigger + Bigger for the same "high"- applies to all drugs - but does it apply to gambling?

DO gamblers think differently?

Cognitive bias describes the inherent thinking errors that humans make in processing information.


  • There will be no difference in skill of RG's and NRG's
  • RG's will have more irrational cognition than the NRG's (using heuristics)

  • Whether participant was a RG or NRG
  • Whether the participant thought aloud or not


  • Total play, total time, play rate, end stake, wins and win rate 


30 regular gamblers and 30 non regular gamblers.

  • RG - 29 males + 1 women who played at least once a week
