信息沟通对转基因食品公众态度的影响研究

根据霍夫兰关于态度改变的信息学习法,对信息性质(单面信息或双面信息)对公众转基因食品态度的影响进行了控制实验。结果表明:信息性质对公众关于转基因食品态度影响显著,但不同信息性质的影响不同;肯定信息作用下公众对转基因食品态度偏向积极,否定信息作用下公众对转基因食品态度偏向消极;否定信息对公众态度影响效果比肯定信息更加显著,双面信息作用下公众对转基因食品态度偏向于消极。基于此,提出构建转基因生物风险信息沟通平台时,应充分发挥专家、政府和大众传媒的积极作用,有效整合传播渠道,科学选择传播信息,以助于公众形成对转基因食品的理性态度。

Study on Effects of Information Communication on Public Attitude towards Genetically Modified Foods

Based on Army Experiment and Persuasion Theory of Carl Hovland, this paper carries out the control experiment about how different information influences public attitude towards genetically modified foods（GMF） under the same or similar educational background. The result shows that different information has significant effects on public attitude towards GMF, but the direction is different. The public has the positive attitude towards GMF under positive information, and negative attitude under negative information,with the latter more influential than the former normally and even in a double-sided information circumstance. Therefore, this paper proposes to build a communication platform for GMF risk information,make the most of positive functions of experts, government and mass media, integrate the approaches for communication, select information for communication in a scientific way so as to make the public form a rational attitude towards GMF.
