在教育环境中，群体决策是早期生活所必需的，也是一个运转良好的社会的核心。然而，很少有关于青少年群体决策的研究，尽管这一时期的神经认知发生了重大变化。研究人员研究了“静态”社会背景下的青少年决策，例如在同龄人面前的冒险行为，并在很大程度上认为青少年决策“次优”。目前尚不清楚这些发现是否适用于更动态的社会环境，例如达成群体决策所需的讨论。在这里，我们测试的最优群体决策在不同阶段的青春期。成对的男性前早期青少年（8至13岁）和中晚期青少年（14至17岁）一起执行低水平的知觉决策任务。当他们各自的决定出现分歧时，他们必须通过谈判达成一项共同决定。虽然个体表现存在发展差异，但两个青少年组的联合表现处于成年水平（从先前的研究中获得的数据）。这两个青少年群体达到了预期的水平下，他们的个人信息最佳整合到一个联合决策的联合表现。青少年的关节，而不是个人，性能随着时间的推移而恶化。结果是一致的，最近的调查结果证明的能力，而不是缺点，青少年的社会行为。
Group decision-making is required in early life in educational settings and central to a well-functioning society. However, there is little research on group decision-making in adolescence, despite the significant neuro-cognitive changes during this period. Researchers have studied adolescent decision-making in ‘static’ social contexts, such as risk-taking in the presence of peers, and largely deemed adolescent decision-making ‘sub-optimal’. It is not clear whether these findings generalise to more dynamic social contexts, such as the discussions required to reach a group decision. Here we test the optimality of group decision-making at different stages of adolescence. Pairs of male pre-to-early adolescents (8 to 13 years of age) and mid-to-late adolescents (14 to 17 years of age) together performed a low-level, perceptual decision-making task. Whenever their individual decisions differed, they were required to negotiate a joint decision. While there were developmental differences in individual performance, the joint performance of both adolescent groups was at adult levels (data obtained from a previous study). Both adolescent groups achieved a level of joint performance expected under optimal integration of their individual information into a joint decision. Young adolescents’ joint, but not individual, performance deteriorated over time. The results are consistent with recent findings attesting to the competencies, rather than the shortcomings, of adolescent social behaviour.
