政府信息发布对突发公共卫生事件中负性偏向的引导与消解

作为进化形成的心理机能，负性偏向促进突发公共卫生事件爆发、演化、升级。目前本领域存在政府信息发布研究学科视角单一，忽视民众心理特征；负性偏向研究理论和实践研究脱节，缺乏跨领域计量方式，忽视主客观阻断因素的不足。本项目通过四项研究（10个子研究）从发布主体（“由谁说”）、发布客体（“怎么说”）、受众主体（“对谁说”）三个层面，基于话语分析、心理实验、传递链仿真测查负性偏向在突发公共卫生事件中的表现和传递规律；以政府信息发布为客观变量，民众特征和心理规律为主观变量构建交互作用模型；采用案例、访谈、用户研究法探讨负性偏向的引导和消解路径；最终建立政府信息发布方案并进行优化和效果检验。成果将为建立有效突发公共卫生事件应对模式，创新危机管理提供思路和技术。

As the psychological function of evolution, negativity bias promotes the outbreak, evolution and upgrading of public health emergencies. At present, there are some problems in this field, such as the single perspective of government information release research, the neglect of people's psychological characteristics, the disjunction of negativity bias research theory and practice research, the lack of interdisciplinary research paradigm, and the neglect of subjective and objective blocking factors. In this project, four studies (10 sub Studies) are conducted to investigate the negativity bias in public health emergencies from three levels: the publishing subject ("who says "), the publishing object ("how to say "), and the audience subject ("to whom"), based on discourse analysis, psychological experiments, and transmission chain simulation; the government information release is taken as an objective variable, with the characteristics of the public And psychological law as subjective variables to build interaction model; use cases, interviews, user research methods to explore the guidance and resolution path of negativity bias; finally establish the government information release program and optimize and test the effect. The results will provide ideas and technologies for the establishment of an effective public health emergency response model and innovation of crisis management.
