In this review, we describe the development of prosocial behavior in adolescence as a critical inflection period for social adjustment. Experimental research using prosocial giving tasks demonstrates that adolescents differentiate more between recipients and contexts, suggesting increasing ingroup-outgroup differentiation during adolescence. We also demonstrate that social brain development during adolescence is partly driven by environmental influences, further underlining adolescence as a critical period for social development. The COVID-19 pandemic has had and will have long-term effects on the current generation of adolescents, for which we describe both the risks, resilience factors, and opportunities for engaging in prosocial acts of kindness.

在这篇综述中，我们将青春期亲社会行为的发展描述为社会适应的关键转折期。使用亲社会给予任务的实验研究表明，青少年在接受者和背景之间的差异更大，这表明在青春期增加了内群体外群体的分化。我们还证明，青春期的社会大脑发育部分受环境影响，进一步强调青春期是社会发展的关键时期。COVID-19 大流行已经并将对当代青少年产生长期影响，为此我们描述了参与亲社会善举的风险、复原力因素和机会。
