Long et al. (2006) found that the construction of situation model is conscious while the construction of textbase is unconscious through the two paradigms（IRK and PDP） in text reading. This is inconsistent with the processing theory of Bi-mechanism in text-reading which states that the construction of situation model is unconscious in coherence-based reading while is conscious in focus-based reading. We think that the inconsistence is caused by the nature of experiment material. In this study, two experiments were designed to explore the consciousness of situation model and textbase in coherence-based reading with the two paradigms（IRK and PDP）. A self-paced, line-by-line reading paradigm was used in this study. In experiment 1, 30 University students were asked to read 12 narrative passages. After reading all of the texts, participants received the recognition test. They were instructed to press a key labeled new if they believed the sentence did not appear in one of the texts they had read. Otherwise, the participants were instructed to press a key labeled old,then they were asked to decide whether they had a vivid, clear consciousness of the sentence; if so, they were asked to press a key labeled R (remember). If they did not have a vivid, clear consciousness of the sentence but still believed the sentence had appeared in one of the texts, they were asked to press a key labeled K (know). In experiment 2, 32 University students were asked to read 12 groups narrative passages. Each participant read six blocks of consistent-version texts and six blocks of qualified-version texts, and then they received a recognition test after each block. After reading one block, they were given one instruction (inclusion instruction or exclusion instruction). In inclusion test, participants were asked to respond old if the sentence appeared in either Story A or Story B and were asked to respond new to any new item. In exclusion test, participants were asked to respond old only if the sentence appeared in Story B and were asked to respond new if the sentence was from Story A or if the item was new. In these two experiments, the reading time of target sentence in qualified condition was longer than that in consistent condition. More importantly, there was no difference between the consistent version and qualified version in the rate of consciousness and unconsciousness.The results showed that both the construction of situation model and textbase is unconscious.
