Understanding Emotion and Emotional Contagion Effects on Cooperative Behavior through Game Simulation

In this study, we considered that emotion and emotional contagion influence the success of cooperative behavior, and conducted a simulation using the board game ``Hanabi'', which is suitable for analyzing cooperative behavior. The results of the simulation showed that the score of the model with emotion decreased, confirming the negative influence of emotion on cooperative behavior. The analysis showed that the higher the emotional valence and the higher the arousal level, the more successful the cooperative behavior was. It was also suggested that arousal level was more likely to cause synchronization through emotional contagion than emotional valence.
