摘　　要：Background： Increased ambient temperature has been implicated in increased physical aggression, which has important practical consequences. The present study investigates this established relationship between aggressive behavior and ambient temperature in the highly aggressive context of professional football in the National Football League （NFL）. Methods： Using a publicly available dataset, authors conducted multiple hierarchical regression analyses on game-level data （2326 games）. Results： The analysis revealed that temperature positively predicted aggressive penalties in football, and that this relationship was significant for teams playing at home but not for visiting teams. Conclusion： These results indicate that even in the aggressive context of football, warmer weather contributes to increased violence. Further, the presence of the heat-aggression relationship for the home team suggests that the characteristics of interacting groups may influence whether heat would have an adverse effect on the outcome of those interactions.目的:已有研究表明环境温度升高与身体攻击性增加相关,这一点具有重要的实践意义。本研究旨在调查两者在美国国家橄榄球联盟(NFL)这一高度攻击性环境下的关系。方法:以现有公开数据库为基础,对比赛层面的数据(2326场比赛)进行多元分层回归分析。结果:在橄榄球比赛中,环境温度对攻击性行为判罚有正向预测作用,这一关联在主场队中显著,但在客场队中不显著。结论:本研究结果显示,在橄榄球这种攻击性环境下,气温升高可导致暴力行为增加。此外,燥热与主场队攻击性相关,这表明尽管温度会影响到团体互动结果,但互动团体各自的特点也会对其产生影响。
