在青春期的转型期，社会影响在塑造年轻人的新兴社会身份方面发挥着重要作用，并可能影响他们从事亲社会或危险行为的倾向。在这项研究中，我们研究了来自父母和同龄人的社会影响的神经相关性，这是两个重要的影响来源。十九名青少年（年龄16-18岁）完成了社会影响力的任务，在功能性磁共振成像（fMRI）扫描。来自这两种来源的社会影响，都会在涉及心智化（内侧前额叶皮层、左颞顶交界处、右颞顶交界处）、奖励（腹内侧前额叶皮层）和自我控制（右腹外侧前额叶皮层）的大脑区域引发活动。这些结果表明，心理状态推理，社会奖励和自我控制过程可能有助于青少年评估他人的观点，并克服自己的先行态度的优势力量，以改变他们对他人的态度。研究结果表明，共同的神经网络参与来自父母和同龄人的社会影响。
During the transformative period of adolescence, social influence plays a prominent role in shaping young people's emerging social identities, and can impact their propensity to engage in prosocial or risky behaviors. In this study, we examine the neural correlates of social influence from both parents and peers, two important sources of influence. Nineteen adolescents (age 16-18 years) completed a social influence task during a functional magnetic resonance imaging (fMRI) scan. Social influence from both sources evoked activity in brain regions implicated in mentalizing (medial prefrontal cortex, left temporoparietal junction, right temporoparietal junction), reward (ventromedial prefrontal cortex), and self-control (right ventrolateral prefrontal cortex). These results suggest that mental state reasoning, social reward and self-control processes may help adolescents to evaluate others' perspectives and overcome the prepotent force of their own antecedent attitudes to shift their attitudes toward those of others. Findings suggest common neural networks involved in social influence from both parents and peers.
