The study of young children’s prosocial emotions, especially as they regulate children’s social interactions toward cooperative ends, is burgeoning. We join Algoe (2020) and Tsang (2020) in their assessment that early ontogeny provides a unique window into the study of prosocial emotions, and that the behavioural methods developed to study prosocial emotions in young children could productively be employed across the lifespan. One particularly intriguing question moving forward is to what degree the role of prosocial emotions within kin relationships is comparable to or different from the functions they fulfil in regulating cooperative relationships with nonkin (peers).

对幼儿亲社会情感的研究正在蓬勃发展，尤其是当他们调节儿童在合作目的方面的社会互动时。我们与Algoe（2020）和Tsang（2020）一起评估，早期个体发育为亲社会情感的研究提供了一个独特的窗口，并且为研究幼儿亲社会情感而开发的行为方法可以有效地应用于整个生命周期。向前发展的一个特别引人入胜的问题是亲属情感在亲属关系中的作用在多大程度上与他们在调节与非亲属（同伴）的合作关系中实现的功能相当或不同。
