Peer presence influences risk-taking behavior, particularly in adolescence. Based on the dual system model, this event-related potential study examined whether and how the presence of a peer displayed a preference for risky behavior would increase adolescents' risk-taking by disrupting their cognitive control processes in either emotional or non-emotional contexts. A sample of 106 adolescents (17-19 years of age) completed two Stoop tasks and a Balloon Analog Risk Task under three peer presence conditions. Results revealed that compared to other conditions, the presence of a risk-averse peer caused adolescents to make safer decisions through improving their conflict monitoring (more negative N200-diff), whereas a risk-preference peer's presence led adolescents to more risky decisions through disrupting their conflict resolution (more positive N450-diff) but they were only observed on the Emotional Stroop task. These findings suggest that different peer presence contexts could increase or decrease adolescents' risk-taking behaviors by influencing their cognitive control under an emotional context rather than in a non-emotional context.
同伴在场会影响冒险行为，尤其是在青少年时期。基于双重系统模型，本事件相关电位研究旨在探讨同伴表现出对冒险行为的偏好是否以及如何通过干扰他们在情绪或非情绪情境中的认知控制过程来增加青少年的冒险行为。一项由 106 名青少年（17-19 岁）完成的研究，在三种同伴在场条件下完成了两个 Stoop 任务和一个气球模拟风险任务。结果表明，与其他条件相比，风险规避型同伴的在场通过改善冲突监测（更负的 N200-diff）使青少年做出更安全的决策，而风险偏好型同伴的在场则通过干扰他们的冲突解决（更正的 N450-diff）导致青少年做出更冒险的决策，但这些结果仅在情绪 Stroop 任务中观察到。这些发现表明，不同的同伴在场情境可以通过在情绪情境下影响青少年的认知控制来增加或减少他们的冒险行为，而不是在非情绪情境下。
