Archival data pertaining to 102 instances of serious collective violence were examined in order to study the relationship between ambient temperature and the occurrence of such events. Results indicated that the frequency of collective violence and ambient temperature were curvilinearly related. Specifically, ambient temperature was directly associated with the frequency of collective violence through the mid-80s (degrees Fahrenheit). Beyond this point, however, further increments in temperature were associated with a decreasing incidence of such events. Additional findings indicated that ambient temperature increased significantly during the 7 days preceding the outbreak of collective violence, remained stable during its occurrence, but then decreased significantly in the 3 days following its termination. Possible implications of these findings, as well as their relationship to the results of previous laboratory studies, are discussed.
为研究环境温度与严重集体暴力事件发生之间的关系，对102起严重集体暴力事件的档案数据进行了审查。结果表明，集体暴力事件的发生频率与环境温度呈曲线相关。具体而言，在华氏80多度之前，环境温度与集体暴力事件的发生频率直接相关。然而，超过这一温度点后，温度的进一步升高与此类事件发生率的下降相关。其他研究结果表明，在集体暴力事件爆发前7天环境温度显著升高，在事件发生期间保持稳定，但在事件结束后的3天内显著下降。讨论了这些研究结果的可能影响，以及它们与以往实验室研究结果的关系。
