Abstract: With the development of economics and the acceleration of social transformation, social contradictions become increasingly prominent. Mass-Emergency (ME) is in the spotlight. A plenty of previous studies paid close attentions to ME’s size, information transmission and feedbacks, and also its generation mechanism. Few studies focused on emotions. Even so, how emotions transmit and turn into intergroup emotion was never concerned. ME is the Externalizing Representations of intergroup emotion, and the spreading of intergroup emotion is the power source of ME. Thus aiming at the mechanism of intergroup spreading, trying to build a model which describe the law of intergroup emotion spreading will be significant for dealing with and forecasting ME.Based on system dynamic and emotion theories, this study modeled dynamic mechanism of intergroup emotion-transmission, and named it as “intergroup emotion-transmission model” (INET). It described the mechanism of intergroup emotion-transmission which concerned 3 kinds of person during the transmission: spreaders, ignorant and stiflers. This model inherited merits and took fully disadvantages of former models into account. Using computer simulation and psychological experiments, this study tested basic hypothesis and ecological validity of INET. The experiment was conducted in a computer lab, participants were from 20 classes, amount to 614 colleage students were recruited, 3 participants of each class were randomly selected, MP3 material which was used to trigger emotins was presented to the 3 participants, after the presentation, they can choose to transmit the MP3 to other participants or not, and then report back their choics to experimenter. Experimenter recorded the proportion of the number of the 3 kinds of persons mentioned above every 80 seconds and 3 line charts were drawn to which the Simulation results compared and the error between experiment and simulation data were calculated. Results showed that social sharing and second sharing of emotion, emotional contagion, degrees of intimate and trust between group members were 3 significant factors which could describe the system of dynamic mechanism of spreaders ignorants and stiflers properly: the proportion of spreaders was climb up and then decline; the proportion of stiflers was climb up with a slowing down speed; the proportion of ignorants was decline. The results of this study provided scientific basis both for dealing with and forecasting ME.

摘要： 选取某高校20个教学班级共计614人为被试，采用心理学实证与系统动力学（system of dynamic）与社会网络（social network）建模相结合的研究方法，对群体情绪传播的动力学规律进行了建模，并将模型仿真结果与心理实验结果进行了比对。结果表明，所建立的模型能够较好地刻画出群体情绪传播的动力学规律，具有较高的生态效度。该模型的建立对群体性事件的定量预警与监控提供了基础理论依据。
