The effect of near-miss rate and card control when American Indians and non-indians gamble in a laboratory situation: the influence of alcohol.
Twelve American Indian (AI) and 12 non-AI participants gambled on a slot-machine simulation and on video poker. Prior to the gambling sessions, half of the participants consumed alcohol while the other half consumed a placebo beverage. They then played the slot-machine simulation three times, with the percentage of programmed "near misses" varying across sessions. They also played video poker three times, with the control the players had over holding and discarding cards varying across sessions. Results showed that AI participants played significantly fewer poker hands than did non-AIs and that participants played most when they had the least control over what cards were played. No significant effect of alcohol consumption was observed. Likewise, results failed to show a significant effect of the percentage of near misses when participants played the slot-machine simulation. The present results lend support for the idea that the differences in gambling problems between AI and non-AI reported in the literature are not a function of ethnicity per se. They may also suggest that providing video poker players with accurate information may have the unintended effect of increasing the rate at which they gamble.
