中文摘要：

采用独立记得一知道范式（IRK）和加工分离范式（PDP）探讨说明文阅读中因果推理的意识性。根据关系部分的描述与目标句是否存在逻辑冲突，创设推理成功和推理失败两种实验条件。实验1和2分别使用独立记得一知道范式和加工分离范式进行研究。两个实验的结果都发现推理成功和推理失败在有意识和无意识加工指标上都差异显著，表明说明文阅读中因果推理既影响有意识加工也影响无意识加工，该结果支持和完善了文本阅读双加工理论。

英文摘要：

Two experiments were designed to explore the influence of causal inference on the consciousness of text representation in expository with the two paradigms （IRK and PDP）. In experiment 1, According to the relationship between the elaboration on a characteristic of the thing and the subsequent target sentence, the independent variable had two levels： successful inference version and fail inference version. The dependent variable was the hit rate of ＂remember＂ or ＂ know＂ judgment. In experiment 2, the independent variable was as same as that in experiment 1. The dependent variable was the hit rate of ＂Old＂ judgment and the false alarm rate of ＂New＂ judgment. In these two experiments, the reading time of target sentence in fail inference condition was longer than that in successful inference condition. More importantly, there was remarkable difference between the successful inference version and fail inference version in the rate of consciousness and unconsciousness. The results showed that causal inference not only affects the conscious processing but also the unconscious processing in expository.
