青春期的特点是对社会环境的敏感性增加，因为年轻人与家庭，朋友和社区的关系不断发展。亲社会行为变得更加分化，使得年龄较大的青少年越来越多地给予已知的他人（例如，家人，朋友，而不是陌生人。这种差异可能与参与社会决策的大脑区域的神经处理变化有关。共有269名9-15岁和19-20岁的青少年完成了一项决策任务，在这项任务中，他们可以在接受功能性磁共振成像（fMRI）时向照顾者、朋友和陌生人给钱。对照顾者和朋友的捐赠（以自己为代价）随着年龄的增长而增加，但对陌生人的捐赠在不同年龄段保持较低和稳定。参与认知控制的大脑区域（背外侧和腹外侧前额叶皮层）显示，随着年龄的增长，在向所有接受者做出决定时，血氧水平依赖（BOLD）激活增加;与奖励处理相关的区域（腹侧纹状体和腹侧被盖区）在向所有接受者做出决定时，在所有年龄段都显示出激活增加。与社会认知相关的大脑区域要么不活跃（背内侧前额叶皮层），要么在所有年龄段的人中表现出较低的激活（颞顶交界处和后上级颞沟）。这些发现对于理解大脑发育在青少年时期社会决策复杂性增加中的作用具有重要意义。
Adolescence is marked by an increased sensitivity to the social environment as youth navigate evolving relationships with family, friends, and communities. Prosocial behavior becomes more differentiated such that older adolescents increasingly give more to known others (e.g., family, friends) than to strangers. This differentiation may be linked with changes in neural processing among brain regions implicated in social decision-making. A total of 269 adolescents from 9–15 and 19–20 years of age completed a decision-making task in which they could give money to caregivers, friends, and strangers while undergoing functional magnetic resonance imaging (fMRI). Giving to caregivers and friends (at a cost to oneself) increased with age, but giving to strangers remained lower and stable across age. Brain regions implicated in cognitive control (dorsolateral and ventrolateral prefrontal cortex) showed increased blood-oxygen-level-dependent (BOLD) activation with increasing age across giving decisions to all recipients; regions associated with reward processing (ventral striatum and ventral tegmental area) showed increased activation across all ages when giving to all recipients. Brain regions associated with social cognition were either not active (dorsomedial prefrontal cortex) or showed reduced activation (temporal parietal junction and posterior superior temporal sulcus) when giving to others across all ages. Findings have implications for understanding the role of brain development in the increased complexity of social decision-making during adolescence.
