A gambling decision aid improved optimal play and increased wagers, even after alcohol consumption. Alcohol increased play speed and reliance on guidance, suggesting alcohol-induced myopia.

Area of Science:

  • Decision science
  • Behavioral psychology
  • Neuroscience

Background:

  • Gambling behavior is influenced by risk perception and cognitive states.
  • Decision aids can guide choices in complex scenarios.
  • Alcohol consumption impairs cognitive functions, potentially affecting decision-making.

Purpose of the Study:

  • To evaluate the impact of a decision aid on gambling behavior under alcohol impairment.
  • To examine how alcohol affects compliance with optimal strategies and risk-taking in blackjack.
  • To investigate the role of alcohol-induced myopia in gambling decisions.

Main Methods:

  • Twenty adult men completed gambling and alcohol use screeners.
  • Participants played a computer blackjack game before and after alcohol ingestion.

  • Compliance with a decision aid and wagering patterns were analyzed.

    • Main Results:

    • The decision aid enhanced compliance with optimal play and increased willingness to wager at high stakes.
    • Alcohol consumption (mean peak BAC 0.048%) increased the rate of play.
    • Participants showed reduced decision time and increased reliance on the decision aid after alcohol intake.

    Conclusions:

    • Decision aids can improve gambling choices, even with moderate alcohol impairment.
    • Alcohol-induced myopia may lead to faster, more cue-driven gambling decisions.
    • Findings suggest alcohol impairs nuanced decision-making, increasing reliance on external guidance.
