Gambling in moderation is a socially acceptable behavior and over 60% of the Swedish population gambles every year. It has been seen that slot machines are one of the most addictive and problematic forms of gambling and contribute highly to an addictive behavior. It is unclear why some individuals intensify their gambling behavior over time to extreme levels while others do not. Initial positive response of a drug or as in this case a gambling behavior, most likely influences the likelihood of continuing use in non-addicted individuals. Therefore, we wanted to investigate if recreational gamblers show an altered subjective response to an online gambling challenge, e.g. to casino gambling. The present study was designed to examine the subjective effects after an acute gambling challenge, in healthy recreational gamblers compared with non-gamblers. Eighty-two subjects participated in the study. They were challenged with an acute online slot machine gambling challenge and self-report questionnaires of mood and blood pressure were taken before and after gambling. The gamblers, and more specifically the high recreational gamblers, reported increased stimulative effects after the gambling challenge in comparison to the non-gamblers. Findings suggests that gamblers experience significantly higher arousal effects to an acute online slot machine challenge. This response may be a uniquely predictive behavior for increased risk of gambling addiction.

适度地赌博是一种社会上可以接受的行为，每年有60％以上的瑞典人在赌博。已经看到，投币游戏机是最容易上瘾和成问题的赌博形式之一，并且对成瘾行为做出了很大贡献。目前尚不清楚为什么有些人随着时间的流逝将赌博行为增强到极端水平，而另一些人却没有。药物或在这种情况下的赌博行为最初的积极反应，很可能会影响非成瘾者继续使用药物的可能性。因此，我们想调查娱乐性赌徒是否对在线赌博挑战（例如，赌场赌博）显示出主观反应有所改变。本研究旨在检查健康娱乐性赌徒与非赌徒相比，急性赌博挑战后的主观效果。八十二名受试者参加了这项研究。他们在网上进行了一次激烈的在线老虎机赌博挑战赛，并在赌博前后对情绪和血压进行了自我报告调查问卷。与非赌徒相比，赌徒（尤其是娱乐性高的赌徒）在赌博挑战后增加了刺激作用。研究结果表明，赌徒在面对急性在线老虎机挑战时会感受到明显更高的唤醒效果。这种反应可能是增加赌博成瘾风险的独特预测行为。尤其是娱乐性高的赌徒，与非赌徒相比，赌博挑战后的刺激作用增强。研究结果表明，赌徒在面对急性在线老虎机挑战时会感受到明显更高的唤醒效果。这种反应可能是增加赌博成瘾风险的独特预测行为。尤其是娱乐性高的赌徒，与非赌徒相比，赌博挑战后的刺激作用增强。研究结果表明，赌徒在面对急性在线老虎机挑战时会感受到明显更高的唤醒效果。这种反应可能是增加赌博成瘾风险的独特预测行为。
