摘要: 为探索在突发事件下人群情绪感染规律,控制群体情绪危害,根据现实情绪特性,引入接触关系,改进突发事件情绪感染干预模型(SOSPa-SPSOa),完善群体情绪感染机制;运用Matlab软件对改进的模型进行数值仿真,并分析模型相关参数对情绪感染过程的影响。结果表明:初始消极情绪群体规模增加会提高群体情绪感染时间,但对群体情绪最终平衡状态影响较小;接触感染过程作用效果低于自发感染过程和自发恢复过程;提高自发恢复概率可降低群体情绪感染时间,有利于群体情绪的控制和调节。

Abstract: For the sake of studying the mechanism of emotional contagion in a group and control emotional hazards under emergencies, the authors introduced a concept of contact relation according to the actual emotional characteristics, and improved emergency emotional contagion model (SOSPa-SPSOa), so an improved emotional contagion mechanism in a group was presented. Moreover, the authors discussed the situations that different emotional valences appear in a group with the actual emotional characteristics, analyzed the influence of model parameters on the process of emotional contagion by Matlab. The results indicate that an increase in the initial size of the subgroup showing negative emotions could increase the time of emotional contagion in the group, but the increase has only a marginal effect on the final state of emotional balance, that the effect of contact contagion is lower than that of the spontaneous contagion process or the spontaneous recovery process, and that increasing probability of spontaneous recovery can reduce the time of group emotional contagion, which is beneficial to controlling and regulating group emotions.

Key words: group emotion, emotional valence, emotional regulation, infection law, numerical simulation, emotional contagion model
