青少年更倾向于从事冒险或鲁莽行为, 并且更容易受到同伴影响。从个人特质和社交互动等多个角度探讨的研究结果表明, 同伴对青少年冒险行为存在助长作用, 即当同伴在场时, 青少年的行为会更加冒险。同伴对青少年冒险行为的作用机制可以从心理、神经、遗传、社会文化等多个层面进行解释:在心理层面, 这种影响源于青少年寻求同伴认可和归属感的需要, 以及社会学习的作用; 在神经机制层面, 源于认知控制网络和刺激处理系统的相互作用; 在遗传层面, 源于特定基因的易感性等; 在社会文化层面, 同伴影响会因文化差异而带来程度与表现上的差异。未来研究应从发展、文化心理、构建复杂模型网络等视角深入探究同伴对青少年冒险行为的影响。

Puberty is a unique period during which individuals experience rapid growth in social, emotional and cognitive aspects, yet remain immature. Compared with adults, adolescents are more inclined to engage in risky or reckless behaviors that are detrimental to their physical and mental health, such as smoking, alcohol abuse, and dangerous driving. At the same time, from childhood to adolescence, the influence of parents on adolescents gradually weakens, while the influence of peers gradually increases. Regarding the question of how adolescents’ adventurous behavior is affected by their peers, the results of previous empirical studies are mixed. In addition, the mechanism of this influence, which is a more crucial research question, remains unknown. From the perspectives of personal characteristics and social interaction, this paper reviews the results of previous studies and finds facilitating effect of peers on adolescents' risk-taking behaviors. Specifically, when adolescents complete a risk-taking task, being watched by a peer can increase the adolescent's risk-taking behavior, even when the peers and the participants are not at the same place. When the adolescent and the peer are in the same room, and the peer can communicate with them or even give advice during the task, peers can play an even stronger role in facilitating the adolescent's risk-taking behavior. Compared with the influence from adults, adolescents are particularly sensitive to the influence from their peers. In addition, personal traits (such as resistance to peer influence and gender) and situational factors (such as the certainty of situation: vague/explicit, and different forms of peer participation: cooperation/competition) play a moderate role. The influence of peers on adolescents' risk-taking behavior and its underlying mechanisms can be explained from multiple aspects, including psychology, neurology, gene, society and culture. From the psychological aspect, this influence stems from the needs of adolescents to seek peers’ recognition and belonging, as well as learn from peers (i.e., social learning). From the aspect of neural mechanism, this influence comes from the interaction between cognitive control network and stimulus processing system: when adolescents make decisions involving risks in the presence of a real or virtual companion, activation of the cognitive control network decreases, and that of the reward system increases. From the genetic perspective, the effect may be due to susceptibility of specific genes. For instance, 5-HTTLPR short allele carriers are more sensitive to peer influence. From the social and cultural aspect, while the influence of peers on risk-taking behavior has a certain generality, the degree of the influence differs in different cultural contexts. For example, compared with white adolescents, risk-taking behaviors of non-white adolescents are more likely to be influenced by peers. In collectivist culture, adolescents’ smoking behavior is more positively correlated with that of their peers. Future research should further explore the influence of peers on adolescents' risk-taking behavior from the perspectives of development, cultural psychology and construction of complex model network.
