Abstract：
In this review, we consider the definitions and experimental approaches to emotional contagion and prosocial behaviour in mammals and explore their evolutionary conceptualisation for studying their occurrence in the evolutionarily divergent vertebrate group of ray-finned fish. We present evidence for a diverse set of fish phenotypes that meet definitional criteria for prosocial behaviour and emotional contagion and discuss conserved mechanisms that may account for some preserved social capacities in fish. Finally, we provide some considerations on how to address the question of interdependency between emotional contagion and prosocial response, highlighting the importance of recognition processes, decision-making systems, and ecological context for providing evolutionary explanations.
摘要：
在这次审查中,我们考虑了哺乳动物情感传染和亲社会行为的定义和实验方法，并探索了它们的进化概念化，以研究它们在进化上不同的脊椎动物群中的发生。我们提供了一系列符合亲社会行为和情绪传染定义标准的鱼类表型的证据，并讨论了可能解释鱼类某些保留的社会能力的保守机制。最后,我们提供了一些关于如何解决情感传染和亲社会反应之间相互依存的问题的考虑，强调识别过程的重要性，提供进化解释的决策系统和生态环境。
