Abstract
Electronic gambling machines (EGMs) show a strong association with gambling problems. The high speed of gaming offered by modern EGMs allows playing numerous games in a short span of time, which is thought to contribute to attentional distraction, increased spending and prolonged play. However, the relationship between EGM speeds and potentially risk-related gambling behavior remains unclear. We introduce a novel approach to investigating the role of gaming speed in EGM gambling behavior by examining ‘individual rate-of-play’ (I-ROP) during simulated EGM gambling. A community sample of male regular gamblers (N = 72) played virtual slot machines in pairs offering sequentially adjusted game speeds towards the estimation of a behaviorally expressed preference speed, or I-ROP. This initial experiment aimed to explore the variability of I-ROPs during simulated EGM gambling, and examine behavior while playing EGMs at speeds relative to their I-ROP. Estimated I-ROPs ranged from less than one half second to over seven seconds and were negatively associated with cognitive ability, but not related to problem gambling severity, impulsiveness, or gambling-related cognitions. Subsequent gambling sessions on EGMs offering individually calibrated faster and slower gaming speeds were associated with greater and reduced risk-related gambling behaviors respectively. I-ROPs represent a potentially informative construct for exploring influences of gaming speed on gambling behavior, and may lend insight into potential risk-related behavior an individual vulnerability with respect to commercially available EGMs that warrants additional research.
