青少年时期的亲社会行为变得更加分化，这取决于行为的接受者以及接受者相对于自我成本的感知价值或利益。目前的研究调查了皮质纹状体网络的功能连接如何跟踪亲社会决策的价值，作为目标接受者（照顾者，朋友，陌生人）和给予者年龄的函数，以及它们如何与给予行为相关。261名青少年（9-15岁和19-20岁）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的同时给照顾者、朋友和陌生人钱。结果表明，青少年更有可能给予他人作为亲社会决定的价值（即，对他人的好处相对于对自己的代价之间的差异）增加;这种影响对已知的（照顾者和朋友）比未知的目标更强，并且随着年龄的增长而增加。神经核（NAcc）和OFC之间的功能连接增加的亲社会决策的价值减少的陌生人，但不为已知的其他人，无论选择。在决策过程中，作为价值和目标的函数，这种差异化的NAcc-OFC功能连接也随着年龄的增长而增加。此外，无论年龄大小，当考虑给予陌生人时，相对于已知的其他人，表现出更大的价值相关NAcc-OFC功能连接的个体在目标之间表现出较小的差异化比率。这些发现强调了皮质纹状体发育在支持青春期亲社会发展日益复杂性方面的作用。
Prosocial behavior during adolescence becomes more differentiated based on the recipient of the action as well as the perceived value or benefit, relative to the cost to self, for the recipients. The current study investigated how functional connectivity of corticostriatal networks tracked the value of prosocial decisions as a function of target recipient (caregiver, friend, stranger) and age of the giver, and how they related to giving behavior. Two hundred sixty-one adolescents (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 fMRI. Results indicated that adolescents were more likely to give to others as the value of the prosocial decision (i.e., the difference between the benefit to other relative to the cost to self) increased; this effect was stronger for known (caregiver and friends) than unknown targets, and increased with age. Functional connectivity between the nucleus accumbens (NAcc) and OFC increased as the value of the prosocial decisions decreased for strangers, but not for known others, irrespective of choice. This differentiated NAcc-OFC functional connectivity during decision-making as a function of value and target also increased with age. Furthermore, regardless of age, individuals who evinced greater value-related NAcc-OFC functional connectivity when considering giving to strangers relative to known others showed smaller differentiated rates of giving between targets. These findings highlight the role of corticostriatal development in supporting the increasing complexity of prosocial development across adolescence.
