摘　　要：[目的/意义]基于用户体验视角,揭示用户对社交媒体信息可信度判断的处理路径,以及感知信息负荷、信息内容情绪效价、话题的熟悉程度和评论态度对其可信度判断的影响,为网络虚假信息提供治理思路。[方法/过程]基于精细加工可能性模型(elaboration likelihood model,ELM)理论,采用2*3*2情景实验,利用网络问卷回收数据(N=791),并采用T检验、回归分析等统计方法分析数据。[结果/结论]与感知低信息负荷UGC相比,用户对高信息负荷UGC具有更高的感知可信度;与积极情绪UGC相比,用户对消极和中性UGC具有更高的感知可信度;感知信息负荷与UGC情绪效价存在显著交互效应。负面评论会显著降低用户感知可信度;对用户高熟悉程度的话题,正面评论会显著降低消极和无情绪表达信息内容的感知可信度;对低熟悉程度的话题,正面评论显著降低无情绪表达UGC的感知可信度。[Purpose/Significance]Based on the perspective of user experience,this paper reveals the processing path of social media information credibility judgment,and the influence of perceived information load,emotional valence of information content,topic familiarity and comment attitude on their credibility judgment.It can provide some ideas for the management of online false information.[Method/Process]Based on ELM theory,2*3*2 scenario experiment was adopted,and data were recovered by network questionnaire(N=791).Statistical methods such as T-test and regression analysis were used to analyze the data.[Result/Conclusion]Compared with UGC with low information load,users have higher perceived credibility for UGC with high information load.Compared with positive UGC,users have higher perceived credibility for negative and neutral UGC.A significant interaction effect exists between perceived information load and the emotional valence of UGC.Negative comments can significantly reduce user perceived credibility.For highly familiar topics,positive comments significantly reduce the perceived credibility of negative and emotionless content.For less familiar topics,positive comments significantly reduce the perceived credibility of emotionless UGC.
