使用认知偏见范式，研究组证明了积极的情感传染在大黄蜂。在接受不同强化的彩色花朵训练后，与处于积极情感状态的同种蜜蜂互动的蜜蜂比对照组更快，更有可能降落在模棱两可的彩色花朵上，这表明蜜蜂之间转移了积极的判断偏见。另外的观察和实验表明，情感可以在没有身体接触的情况下在蜜蜂之间传播，即仅通过视觉方式。他们的发现表明，情感传染可能是一种进化上广泛存在的机制，存在于群居脊椎动物和群居昆虫中。
据介绍，情感传染是共情的核心组成部分，在社会脊椎动物中被广泛表征，但在任何无脊椎动物中是否存在情感传染尚不清楚。

Abstract: Affective contagion, a core component of empathy, has been widely characterized in social vertebrates but its existence in any invertebrate is unknown. Using a cognitive bias paradigm we demonstrate positive affective contagion in bumble bees. After being trained on colored flowers with different reinforcements, bees that interacted with a conspecific in a positive affective state were quicker and more likely than controls to land on ambiguous colored flowers, indicating the transfer of a positive judgment bias between bees. Additional observations and experiments showed that affect could be transmitted between bees without physical contact, i.e., through visual modality alone. Our findings suggest that affective contagion may be an evolutionarily widespread mechanism present in both social vertebrates and social insects.
