A new study by Havlik et al. (Science Advances, 6(28), eabb4205, 2020) reveals that rats are less likely to help a conspecific in need in the presence of passive bystanders, but that they are more likely to help when there are active bystanders that engage in helping. This study highlights the social skills of rats and the role of bystanders on cooperation, raising a range of interesting questions that should be explored both theoretically and empirically.

Havlik 等人的一项新研究。( Science Advances , 6 (28), eabb4205, 2020) 表明，在被动旁观者面前，老鼠不太可能帮助有需要的同种动物，但当有积极的旁观者参与帮助时，它们更有可能提供帮助。这项研究强调了老鼠的社交技能和旁观者在合作中的作用，提出了一系列有趣的问题，应该从理论上和经验上进行探索。
