The goal of this research is to test the effects of sounds that accompanies winning combinations on a slot machine simulator. This type of slot game features a random number generator which instantly determines where each “reel” stops and the payout amounts. Sounds are used to accompany winning combinations, and losses are disguised by sound, making them appear as wins. Previous studies have found that without sound, players overestimate the number of times they win. When sounds are present, however, the tendency to overestimate wins is exacerbated, leading to a propensity to gamble more than one would otherwise based on past experience. This gambling problem can have severe consequences, including financial ruin and issues with family, friends and work. While the majority of gamblers enjoy this form of entertainment as harmless fun, a subset of these players experiences severe problems that may include mounting debt and involvement in criminal activities to support their gambling behavior (Blaszczynski, Sharpe, Walker, Shannon and Coughlan, 2005). Understanding the allure of slots is essential in preventing gambling-related harms.
