一项有关男性赌徒的研究发表在《赌博研究杂志》上，该研究发现：赌徒的臂膀里搂着个姑娘，确实会带来某种“运气”，当玩老虎机的赌徒有女性陪伴时，他们输得会更少。
我很想把这个称为“詹姆斯·邦德效应”，但是在赌博中，好运气是相对的。所以，假如你认为这意味着，把你辛苦赚来的钱哗哗地倾入下水道中，只不过运气好的时候倒得比以往稍微少那么一点，那么也许幸运女神就是你的指路明灯。
这项研究也发现了老虎机赌博对情绪一个有趣的影响：赌博前感觉低落的人们，会很兴高采烈，而那些事先觉得开心，或感受中立的人们，事后会觉得更糟。
有关环境因素与赌博行为的关联，人们知之甚少。我们招募了180名男性受试者（平均年龄：21.6岁），在参加视频彩票终端机上进行赌博前，诱发他们进入正性、中性，或负性情绪状态。在赌博时，有男性同伴、女性同伴，或没有同伴观看受试者。诱发情绪对赌博行为没有影响。但在赌博前被诱发负性情绪的受试者，在赌博后会报告更多的正性情绪，而被诱发正性或中性情绪的受试者，在赌博后会报告更多的负性情绪。与没有同伴的受试者相比，由男性或女性同伴观察的受试者，花费更少的时间在视频彩票终端机上进行赌博。而相对于其他观看条件，被女性同伴观看的受试者，输掉的钱更少。在过去一年中有问题赌博行为的程度，对这些效应均有轻微影响。我们讨论了这些发现的部分现实意义。

A study on male gamblers just published in the Journal of Gambling Studies found that having a girl on your arm does bring ‘luck’ of sorts, as slot machine gamblers had fewer losses when accompanied by a female.
I am tempted to label this the ‘James Bond Effect’ but in gambling, good fortune is relative, so if you think good luck means pissing slightly less of your hard earned cash down the drain than you would have done anyway, may lady luck be your guiding light.
The study also found an interesting effect of slot machine gambling on mood: people feeling low beforehand cheered up, while those who felt happy or neutral felt worse afterwards.

Little is known about the situational factors associated with gambling behavior. We induced 180 male participants （mean age: 21.6） into a positive, negative, or neutral mood prior to gambling on a video lottery terminal （VLT）。 While gambling, participants were observed by either a male peer, female peer, or no one. Induced mood had no effect on gambling behavior. Participants induced into a negative mood prior to gambling, however, reported more positive moods after gambling, whereas those with positive and neutral moods reported more negative moods after gambling. Participants observed by either a male or female peer spent less time gambling on the VLT compared to those not observed. Participants observed by a female peer lost less money relative to the other observer conditions. Degree of problem gambling in the last year had little influence on these effects. Some practical implications of these findings are discussed.
