知识验证信念对于多文本阅读理解的影响机制:阅读策略的中介效应和主题知识的调节效应

为厘清知识验证信念对于多文本阅读理解的影响机制，本研究构建了有调节的中介模型。采用知识验证信念量表、主题知识问卷和阅读策略量表，对于173名大学生进行调查，并要求其在多文本阅读理解之后进行开放问题回答。结果显示：精致化策略和信息收集策略在知识验证信念对于多文本阅读理解的影响中起部分中介作用；知识验证信念对于精致化策略的预测作用受到主题知识的调节。该结果不但展示了知识验证信念对于多文本阅读理解的间接影响机制，也提示了主题知识的作用在于提供了选择复杂策略的自由。

Justification Belief on Multiple-text Comprehension:Mediation of Reading Strategies and Moderation of Topic Knowledge

In order to clarify the specific mechanism underlying the relationship between justification belief and multiple-text comprehension, this study conducted a moderated mediation model in a sample of 173 undergraduate students. Participants' justification belief, topic knowledge, and reading strategies were measured. In addition, they were required to answer three related open-ended questions directly after reading five conflict texts on cellphone radiation. Results showed that: (1) justification belief had positive indirect effects on multiple-text comprehension separately through accumulation strategy and elaboration strategy; (2) the relationship between justification belief and elaboration strtegy was moderated by topic knowledge. Our findings identified the underlying mechanisms of justification belief on multiple-text comprehension, and further s suggested that topic knowledge play an important role in using complicated strategies.
