Pleasant weather conditions (i.e., sunshine) favor positive social relationships and improve mood. However, the effect of sunshine on spontaneous helping still remains in question. In a field experiment, male and female confederates accidentally dropped a glove on the ground while walking in pedestrian streets. The confederate continued walking, apparently unaware of his/her loss. The experiment was conducted on predominantly cloudy or predominantly sunny days, but precaution was taken to control for the temperature and not to solicit participants when it rained. Passers-by helped the confederates more favorably on the sunnier days. Positive mood induced by sun may explain such results.
宜人的天气条件（如阳光）有利于积极的社会关系并改善情绪。然而，阳光对自发帮助的影响仍存在争议。在一项现场实验中，男性和女性的同谋在步行街行走时不小心将手套掉在地上。同谋继续走着，显然没有意识到自己的损失。实验在主要是阴天或晴天进行，但要注意控制温度，下雨时不要招揽参与者。在阳光更充足的日子里，路人更愿意帮助同谋。阳光带来的积极情绪可能解释了这些结果。
