EMOTION-III Model: A Theoretical Framework for Social Empathic Emotions in Autonomous Control Systems: In this article, a theoretical model of social empathic emotion is derived based on the principles of survival by extending the maximization of self-gains to include others as an extended-self. This extended-self model of optimization for survival provides the computational mechanisms in the optimization process to maximize self-gains without minimizing the gains (or maximizing losses) for the other individuals. Thus, it can resolve conflicts in a competitive environment, and change the social dynamics into a cooperative interaction instead.
