Cognitive architectures are subset of general agent architectures, which try to model human cognitive process for intelligent agents. Modeling emotional process in thesearchitectures was followed by many researchers. Ortony et al. [1] proposed three levels of information processing, reactive, routineand reflective, with four functions, perception, affect, motivation, cognition, and behavior Kazemifard et al. [2] implemented anddetailed this model in a multi-agent system. The undeniable effectof personality on emotions and many proving experiments demonstrated that a critical function is missing in this model.This deficiency becomes bolder when the environment is multiagent. In this paper, Kazemifard et al. [2] is improved within twoways. Firstly, using Five Factor Model of personality, another function, personality, is introduced, and its interactions withother functions are explained. Secondly, effective sociality isconstructed among agents with different personalities to improve sharing of knowledge and subsequently helpful cooperation. This is important since the fundamental benefit of multi-agent environment is decentralized exploration. Finally, this architecture is implemented in a predator-prey environment, and its selective applications are discussed.
