青少年风险偏好增加的神经基础是什么?

What is the neural basis of increased adolescent risk taking?

青少年奖赏系统(如腹侧纹状体)对同伴与新鲜刺激高度敏感,而认知控制的前额叶成熟滞后,造成“油门快、刹车慢”。在情绪唤醒或同伴在场时,这种失衡尤为明显。它从机制上解释了为何青春期冒险多于儿童或成人。
Adolescent reward systems, such as the ventral striatum, are highly sensitive to peers and novelty, while the cognitive-control prefrontal cortex matures later, creating a fast accelerator and slow brake. The imbalance is strongest under arousal or peer presence. It mechanistically explains why risk-taking peaks in adolescence.

同辈压力如何影响青少年的行为与决策?

How does peer pressure affect adolescent behavior and decisions?

青少年对同辈接纳高度敏感,群体在场会放大奖赏预期并削弱风险警觉,使其更易冒险或顺从。研究显示有同伴旁观时青少年冒险行为增加,而儿童与成人则不明显。理解这一点有助于用建设性同伴关系替代负面从众。
Adolescents are highly sensitive to peer acceptance; peers present amplify reward anticipation and dull risk caution, increasing risk-taking or conformity. Studies show risk-taking rises with peers watching, unlike in children or adults. Understanding this helps build constructive peer ties over negative conformity.

埃里克森所说的青少年“同一性危机”是什么?

What is Erikson's adolescent identity crisis?

埃里克森把青少年期看作“同一性对角色混乱”的阶段,青少年要回答“我是谁、要成为怎样的人”。积极探索价值观与职业并形成稳定同一性是健康结果;回避探索则可能导致迷茫或被动接受他人定义。同一性并非一次定型,而会在一生中重塑。
Erikson saw adolescence as identity versus role confusion, where teens ask who am I and what to become. Actively exploring values and careers to form a stable identity is the healthy outcome; avoiding exploration leads to confusion or accepting others' definitions. Identity is not fixed once but reshaped across life.
