基于心理阈值模型的危机事件下从众行为动力学分析
The Analysis of Group Behavior Dynamics in Crisis Based on Psychological Threshold Model
摘要
Abstract
The science of psychological and behavior in crisis is one of the five core scientific issues in the public emergency management. The different herd behavior reflects different dynamics in the public crisis. First, this paper develops a threshold model for behavior cognitive processes from the psychological perspective, in which four types of behavior cognitive processes, I. E. , repetition, deliberation, imitation and social comparison, are defined basing on the unity threshold and uncertainty threshold. Then the paper uses the multi-agent simulation to explore the dynamics of group behaviors. The simulation results show that those four cognitive processing will dominate the artificial agents' behavior selection with different proportion, respectively under different conditions, come to determine the dynamic characteristics of group behaviors, such as Herding lock-in. Psychological factors and social factors that affect the four types of cognitive processes include the interaction between the agents' decision-making process, the social network structure of interactions between agents, and the importance to explain the dynamics of group behavior.关键词
