摘要
本文首先概述了观点动向的研究领域和目前研究进展.在社会认同理论基础上区分出群体决策过程具体的三种社会影响,进一步赋予了Hopfield网络模型二元组间社会连带(social ties)的具体社会学内涵.基于此模型仿真研究了群体在具有自我认同、社会归属条件下的群体观点分化现象.模型仿真得到群体外生变量的干涉和负社会影响是推动群体观点极化的主要因素.特别地,仿真结果表明群体观点极化与三元组(社会学中研究的基本结构)影响模块结构平衡密切相关,从社会心理学角度解释了具有符号关系的群体宏观动态模式和微观结构变化之间的联系.
In this study, firstly we brief the research fields and recent development related to opinion dynamics. We classify three types of social influence of group decision making from the perspective of social identity, and assign specific social influence implication to dyadic social ties of Hopfield model. Based on the model, we conduct simulations on the group polarization phenomena under the condition of self-recognition and social belongings. Simulation results verify that exogenous covariate and non- positive social influence are the main factors that promote group polarization. Especially, it is shown that polarization is coexisted with local structure balance, which provides social-psychological implications about local patterns of signed relationships from collective action perspective.
