Economic games are well-established experimental paradigms for modeling social decision making. A large body of literature has pointed to the heterogeneity of behavior within many of these games, which might be partly explained by broad interpersonal trait dispositions. Using the Big Five and HEXACO (Honesty-Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness to Experience) personality frameworks, we review the role of personality in two main classes of economic games: social dilemmas and bargaining games. This reveals an emerging role for Big Five agreeableness in promoting cooperative, egalitarian, and altruistic behaviors across several games, consistent with its core characteristic of maintaining harmonious interpersonal relations. The role for extraversion is less clear, which may reflect the divergent effects of its underlying agentic and affiliative motivational components. In addition, HEXACO honesty-humility and agreeableness may capture distinct aspects of prosocial behavior outside the bounds of the Five-Factor Model. Important considerations and directions for future studies are discussed within the emerging personality-economics interface.

人际特质在社会决策中的作用：探索经济博弈中行为异质性的根源。

经济博弈是建立社会决策模型的公认实验范式。大量文献指出了许多这类游戏中行为的异质性，这可能部分由广泛的人际特质倾向所解释。使用“五大”和“六方”（诚实，谦卑，情感，性外向，和,、认真，体验开放）性格框架，我们回顾了性格在经济游戏的两个主要类别中的角色：社会困境和讨价还价游戏。这揭示了五国协议在促进多个游戏中的合作，均等和利他行为方面正在发挥的作用，这与其保持和谐的人际关系的核心特征是一致的。外向性的作用还不清楚，这可能反映了其潜在的代理和附属动机成分的不同影响。此外，HEXACO的诚实与谦逊可能会超越五因素模型，从而体现亲社会行为的不同方面。在新兴的人格-经济学界面中讨论了重要的考虑因素和未来研究的方向。
