Abstract: Through thorough analysis of the emotion-related theories in psychology and microeconomics, the attributes of emotion were clarified whose essence is energy, function is driving behavior, sort reflects the sort of survival resources,and the emotional essence of motivation, (inner) drive and utility(subjective value) was discovered. According to the common law abided by these kinds of sense, and consulting Prospect Theory, emotion schema function was built up to obtain the principle of functional relationship between emotion and living resource. Based on these work, adopting optimistic selection principle, emotion-driven behavior selection mechanism was established. In order to validate the mechanism, emotion-driven competitive, cooperative behavior selection mechanism and fight behavior selection mechanism were constructed and simulations of them on platform Swarm were achieved. The simulation results confirm the proposed mechanism. Thus,the theory base of autonomous behavior selection achievement under uncertain conditions is provided.
