Abstract: In recent years, the connection between emotions and cooperative behavior has received widespread attention. Aiming at the limitations of the emotional state hypothesis in the traditional spatial evolutionary game model, this study introduces a novel memory-based emotion mechanism. By treating emotion as a variable that can be measured and accumulated, and incorporating it into a network reciprocity model, this paper explores how emotion affects cooperative behavior in social dilemmas with different dilemma strengths. It is worth noting that the accumulated length of memory for emotions is variable. Using Monte Carlo simulation, the study analyzed the roles of positive and negative emotions in three social dilemmas and their specific effects on cooperative tendencies. The findings of this paper emphasize the importance of emotional dynamics and suggest that emotions can address some difficult problems. We propose potential applications of this mechanism in social governance and policymaking.
