Adolescence is often characterized by heightened risk‐taking behaviors, which are shaped by social influence from parents and peers. However, little is understood about how adolescents make risky decisions under conflicting influence. The valuation system in the brain may elucidate how adolescents differentially integrate conflicting social information. Twenty‐eight adolescents (M_age = 12.7 years) completed a social influence task during a functional magnetic resonance imaging scan. Behaviorally, adolescents took more risks only when their parent endorsed risky decisions but not when their peers endorsed risky decisions. At the neural level, adolescents showed enhanced vmPFC–striatum functional connectivity when they made risky decisions that followed their parents’ risky decisions. Results suggest that parents’ decisions may guide youths’ risk‐taking behavior under conflicting influence.

冲突社会影响对青少年冒险行为的神经相关性

青春期的特征通常是冒险行为增加，这是由父母和同龄人的社会影响所塑造的。然而，人们对青少年如何在相互冲突的影响下做出冒险决定知之甚少。大脑中的评估系统可以阐明青少年如何差异化整合相互冲突的社会信息。二十八名青少年（M_年龄 = 12.7 年）在功能性磁共振成像扫描期间完成了一项社会影响任务。在行为上，青少年只有在父母支持冒险决定时才会承担更多风险，而在同龄人支持冒险决定时则不会。在神经水平上，当青少年遵循父母的冒险决定做出冒险决定时，他们表现出增强的 vmPFC-纹状体功能连接。结果表明，父母的决定可能会指导青少年在冲突影响下的冒险行为。
