在从依赖父母的儿童向完全自主的成年人转变的过程中，同伴在青少年行为的塑造中扮演着重要的角色。然而，来自同伴的影响并不总是积极的。在这里，我们探讨了在青春期早期抵抗同伴影响的概率的个体间差异的神经相关性。使用功能性磁共振成像，我们发现10岁的儿童之间的显着差异，高和低阻力的同伴影响在他们的大脑活动在观察愤怒的手部动作和愤怒的面部表情：与受试者相比，低阻力的同伴影响，高阻力的个人表现出高度协调的大脑活动的神经系统的行为和决策的感知。这些研究结果表明，抵抗同伴影响的概率取决于神经的相互作用，在观察充满情绪的行动。
During the shift from a parent-dependent child to a fully autonomous adult, peers take on a significant role in shaping the adolescent's behavior. Peer-derived influences are not always positive, however. Here, we explore neural correlates of interindividual differences in the probability of resisting peer influence in early adolescence. Using functional magnetic resonance imaging, we found striking differences between 10-year-old children with high and low resistance to peer influence in their brain activity during observation of angry hand movements and angry facial expressions: compared with subjects with low resistance to peer influence, individuals with high resistance showed a highly coordinated brain activity in neural systems underlying perception of action and decision making. These findings suggest that the probability of resisting peer influence depends on neural interactions during observation of emotion-laden actions.
