该研究通过年龄-时期-队列分析，发现Z世代社会互动相关人格特质与其他世代存在差异，但亲社会核心特质稳定，揭示队列变化具有选择性
AI 中文摘要
世代刻板印象普遍存在，但往往依赖轶事，难以区分真实的出生队列差异与衰老和历史时期的普遍影响。我们采用可分离年龄、日历时间和队列效应的统计方法，分析了30年间评估的N=773714人的大五人格（五大宽泛人格维度）数据。塑造社会互动的特质在不同世代间存在差异，而由道德、自律和情绪觉察构成的亲社会核心在各队列间保持稳定。Z世代（1995-2012年出生）表现出更低的刺激寻求性和合群性，同时具有更高的自我意识和焦虑水平。这些发现表明，队列变化是选择性的而非全球性的：人们参与社会世界的倾向可能正在适应当代文化条件，而核心亲社会倾向在各世代间保持稳定。
英文摘要
Generational stereotypes are widespread, but they often rely on anecdotes, and it remains challenging to disentangle true birth-cohort differences from the universal effects of ageing and historical periods. Using a statistical approach that separates effects of age, calendar time, and cohort, we analyzed Big Five personality data (five broad dimensions of personality) from N=773,714 individuals assessed across 30 years. Traits that shape social interaction diverged between generations, whereas a prosocial core comprising morality, discipline, and emotional awareness was stable across cohorts. Generation Z (born between 1995 and 2012) showed lower excitement seeking and gregariousness alongside higher self-consciousness and anxiety. These findings suggest that cohort change is selective rather than global: the dispositions through which people engage with the social world may be adapting to contemporary cultural conditions, while core prosocial tendencies remain stable across generations.
