This study explored the effect of near-misses in online slot machine gambling. Near-misses occur when a gambling outcome is close to a win but is still a loss. Near-misses are common in slot machines and can make people feel like they almost won, encouraging them to continue gambling. Previous research has shown mixed results on how near-misses affect motivation, emotions, and betting behaviour. The researchers conducted three studies to examine different aspects of gambling behaviour and subjective experience of near-misses. The researchers found that near-misses increased motivation to continue gambling and were rated more positively than full losses. Near-misses also led people to start their next spin faster and to bet a greater amount of money. The findings indicate that near-misses significantly impact gambling behaviours and subjective experiences.
