The current study attempted to alter gambling bets made during a simulated game of craps using a multiple baseline design. Participants were open to wager between 0-3 chips per trial. All participants completed a four phase sequence throughout the session. The first phase was a training phase where participants wagered and rolled dice five times. At the start of the second phase, which was baseline, participants were told that they have 100 chips to wager with, they will earn half of the amount of chips they accumulate for extra credit in a college graduate class. A probability instruction using Microsoft PowerPoint was the third phase. Finally, during the fourth phases participants were given 100 chips and played the number of trials they had during the baseline phase. Decreasing average bets per phase illustrates the ability to alter gambling behavior through probability training.
