Three levels of information processing: Improvement using personality

Abstract

Cognitive architectures are subset of general agent architectures, which try to model human cognitive process for intelligent agents. Modeling emotional process in these architectures was followed by many researchers. Ortony et al. [1] proposed three levels of information processing, reactive, routine and reflective, with four functions, perception, affect, motivation, cognition, and behavior Kazemifard et al. [2] implemented and detailed this model in a multi-agent system. The undeniable effect of 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 multi-agent. In this paper, Kazemifard et al. [2] is improved within two ways. Firstly, using Five Factor Model of personality, another function, personality, is introduced, and its interactions with other functions are explained. Secondly, effective sociality is constructed 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.
