谣言是常见的社会现象,但其传播过程的“心理黑箱”还是缺乏探索的问题。在情绪评价理论的基础上,采用对照实验,通过转基因食品情景模拟来考察不公平谣言及辟谣行为对风险认知评价及情绪的影响。结果表明:(1)转基因风险评价产生的情绪可分为后果型和伦理型;(2)不公平感会导致更强烈的伦理型及后果型情绪,并使得被试倾向于高估转基因风险;(3)辟谣对转基因风险评价能起到一定干预作用,但不能完全抵消谣言对情绪的影响。 Rumor is a common social phenomenon, but its “psychological black box” in the process of communication still lacks exploration. Based on the theory of emotion evaluation, this paper uses control experiments to investigate the impact of unfair rumor and rumor behavior on risk perception evaluation and emotion through the simulation of genetically modified foods. The results showed as follows: (1) Emotions generated by GMO could be divided into consequence and ethics; (2) unfairness would lead to stronger ethical and consequence sentiment, and subjects tended to overestimate the risk of transgenics; (3) The rumor can play a certain role in the evaluation of the risk of GMO, but it can not completely nullify the rumor’s influence on emotion.
