In this paper, we elaborate on the design and discuss the results of a multi-agent simulation that we have developed using the PSI cognitive architecture. We demonstrate that imbuing agents with intrinsic needs for group affiliation, certainty and competence will lead to the emergence of social behavior among agents. This behavior expresses itself in altruism toward in-group agents and adversarial tendencies toward out-group agents. Our simulation also shows how parameterization can have dramatic effects on agent behavior. Introducing an out-group bias, for example, not only made agents behave aggressively toward members of the other group, but it also increased in-group cohesion. Similarly, environmental and situational factors facilitated the emergence of outliers: agents from adversarial groups becoming close friends. Overall, this simulation showcases the power of psychological frameworks, in general, and the PSI paradigm, in particular, to bring about human-like behavioral patterns in an emergent fashion.

本文基于PSI认知体系的多智能体模拟，探讨了如何通过内在的集体归属，确定性和能力需求，在智能体之间产生社会行为。实验结果表明参数化可以在行为上产生戏剧性影响，例如引入外部群体倾向不仅让智能体对其他群体表现出攻击性和亲和力，而且还增加了内部凝聚力。这个模拟显示了使用心理学框架，特别是PSI范式，来引发出类似人类的行为模式的能力。
