同伴在场使青少年更爱冒险:来自脑科学研究的证据

Peer Presence Makes Adolescents More Risk Taking: Evidence from Brain Science Research

青春期是冲动冒险的高发期,从事冒险行为不仅会给青少年的健康发展造成极大威胁,也可能会威胁社会的稳定发展。已有研究证实,相比于独自一人,同伴在场会加剧青少年的冒险决策。基于双系统模型和三角模型的观点,神经科学的研究也发现,同伴在场可能会通过增强奖励敏感性,降低认知控制水平来影响青少年冒险行为。未来研究可从神经动态网络层面继续完善同伴在场影响冒险行为的脑机制研究,进一步规范同伴在场的操纵,并重视青少年冒险行为的本土化研究。

Adolescence is a high incidence period of impulsive risk-taking. Engaging in risk-taking behavior will pose a great threat not only to the healthy development of teenagers, but also to the stable development of society. Studies have shown that peer presence exacerbates teenagers’ risky decisions than being alone. According to two-system model and triangular model, neuroscience studies have also found that peer presence may influence adolescent risk-taking behavior by enhancing reward sensitivity and reducing the level of cognitive control. Future research can continue to improve the brain mechanism of peer presence influencing risk-taking behavior from the perspective of neural dynamic network, further standardize peer presence manipulation, and pay attention to the localization study of adolescent risk-taking behavior.
