Adolescence is characterized by extensive neural development and sensitivity to social context, both of which contribute to engaging in prosocial behaviors. Although it is established that prosocial behaviors are linked to positive outcomes in adulthood, little is known about the neural correlates of adolescents' prosociality. Identifying whether the brain is differentially responsive to varying types of social input may be important for fostering prosocial behavior. We report pilot results using new stimuli and an ecologically valid donation paradigm indicating (1) brain regions typically recruited during socioemotional processing evinced differential activation when adolescents evaluated prosocial compared with social or noninteractive scenes (N = 20, ages 13-17 years, M = 15.30 years), and (2) individual differences in temporoparietal junction recruitment when viewing others' prosocial behaviors were related to adolescents' own charitable giving. These novel findings have significant implications for understanding how the adolescent brain processes prosocial acts and for informing ways to support adolescents to engage in prosocial behaviors in their daily lives.
青春期的特点是广泛的神经发育以及对社会环境的敏感性，这两者都促使人们做出亲社会行为。虽然已经确定亲社会行为与成年后的积极结果相关，但对于青少年亲社会性的神经关联却知之甚少。确定大脑对不同类型社会输入的反应是否存在差异，可能对培养亲社会行为很重要。我们报告了使用新刺激和生态有效捐赠范式的初步结果，表明：（1）当青少年评估亲社会场景与社会场景或非互动场景时（N = 20，年龄13 - 17岁，M = 15.30岁），社会情感处理过程中通常会被激活的脑区表现出不同的激活；（2）观看他人亲社会行为时颞顶联合区激活的个体差异与青少年自己的慈善捐赠有关。这些新发现对于理解青少年大脑如何处理亲社会行为以及为支持青少年在日常生活中做出亲社会行为提供信息具有重要意义。
