Mechanism of Constructing and Updating Situation Models in Text-Reading
文本阅读中情境模型建构和更新的机制

Moving window display technique was used to investigate the mechanism of constructing and updating situation models in text-reading.According to whether the characteristic elaboration was consistent with subsequent target action carried out by the protagonist,the experimental materials were divided into three categories: enablement,disablement and re-ablement version.In experiment 1, the mechanism of constructing and updating situation models in text with explicit goal information was investigated to support the here-and-now hypothesis.In experiment 2,the mechanism of constructing and updating situation models in text without explicit goal information was investigated to support the memory-based text processing view.In experiment 3,the difference between the here-and-now hypothesis and the memory-based text processing view was further investigated with probe tasks.The results indicated that the mechanism of constructing and updating situation models in text-reading was different with the changing of information.A processing theory of bi-mechanism for constructing and updating situation models is suggested,which proposes that the mechanism of constructing and updating situation models in normal reading includes both coordinating integration supported by the memory-based text processing view and goal-information integration supported by the here-and-now hypothesis.
