The opinions of peers are among the most potent factors influencing human decision-making. Research conducted in Western societies suggests that individuals become more resistant to peer influence from late adolescence to adulthood. It is unknown whether this developmental trajectory is universal across cultures. Through two cross-national studies, we present consistent self-report and behavioral evidence for culturally distinct developmental trajectories of resistance to peer influence (RPI). Our findings from the US samples replicated prior findings that reported increasing RPI. Yet, data from the Chinese participants were better fitted using a nonlinear model, displaying a U-shaped trajectory with lowest RPI levels at around 20 years old. In contrast to the long-held belief that increasing RPI from adolescence to early adulthood is a universal developmental trait, we propose that this developmental trajectory may depend on cultural context.
同辈的意见是影响人类决策的最有力因素之一。在西方社会进行的研究表明，个体从青春期后期到成年期变得更能抵抗同辈的影响。目前尚不清楚这种发展轨迹在文化上是否普遍存在。通过两项跨国研究，我们提供了一致的自我报告和行为证据，证明了抵抗同辈影响（RPI）的文化独特发展轨迹。我们从美国样本中得到的发现复制了先前报告的 RPI 增加的发现。然而，来自中国参与者的数据使用非线性模型拟合得更好，显示出大约 20 岁时 RPI 水平最低的 U 形轨迹。与从青春期到成年早期 RPI 增加是普遍的发展特征的长期观点相反，我们提出这种发展轨迹可能取决于文化背景。
