摘　　要：为探查个体对于网络信息选择性暴露的成因及可能的影响因素,研究在测量大学生被试的信念一致性后,使用真实搜索情境中的网页链接作为阅读材料,要求347名大学生被试评价相关网页链接的可信度、引发的积极情绪和消极情绪以及选择网页链接进行详细阅读的意愿。数据分析显示,大学生被试的信念一致性通过可信度的完全中介作用间接影响信息选择,而积极情绪则对于可信度-信息选择的影响路径起着调节作用,构成了有调节的中介效应模型。研究结果表明评价偏误可能是选择性暴露的主要原因,而积极情绪则能够调节评价偏误对于选择性暴露的影响。In the information age,people's stand tends to be extreme rather than moderate,one of the main reasons is selective exposure.Selective exposure means that individuals choose to be exposed to the information environment with belief-consistency,which is manifested in the fact that individuals are more willing to choose information with belief-consistency for reading,rather than information that challenges the original beliefs.In the Internet era,people choose information more freely and conveniently,which enlarges the harm of selective exposure.Therefore,the theoretical explanation of selective exposure has become the focus of attention for researchers.On this topic,there is still a theoretical dispute between the theory of evaluation bias and the theory of cognitive dissonance.In order to explore the relationship between evaluation bias and selective exposure,and to verify the possible regulatory effect of emotion on both,this study took"mobile phone radiation and health"as the theme,compiled eight related webpage links and presented them in the form of real search context.First of all,347 college students'belief-consistency was measured.After reading the web links,the subjects were asked to evaluate their credibility,positive and negative emotions,and further information selection.Through the moderated mediating effect,the data were statistically analyzed in order to obtain the overall model among belief consistency,credibility evaluation,emotion and information selection.Data analysis showed that the belief-consistency of college students indirectly affected information selection through the complete mediating effect of credibility,while positive emotion played a moderating role in the influence path of credibility information selection,forming a moderated mediation model.The results showed that there was a completion mediation effect between belief-consistency,credibility and information selection,that is to say,evaluation bias is the direct cause of selective exposure.Individuals do not blindly choose informa
