Ecological validity of laboratory studies of videopoker gaming

This study compared the cognitive and behavioral components of videopoker players under laboratory and natural settings. Twenty regular gamblers (19 men and 1 woman) were matched into two groups on age and on frequency of gambling. Irrational verbalizations during gambling, monetary risk (number of bets doubled and number of tokens bet), and motivation served as dependent variables. Results showed no significant differences between laboratory and natural settings for the number of inadequate verbalizations, bets doubled, and motivation. The amount of money gambled was greater in the laboratory than in the natural setting. The practical and theoretical implications of these results are discussed according to the ecological validity of gambling studies conducted in laboratory settings.
