采用移动窗口阅读技术探讨记叙文中倒叙事件的时间表征模式。实验1检验了实验材料的适宜性，实验2、3分别采用照应句范式和探测技术探讨时间顺序假设与背景信息假设的合理性。结果发现：当事件E1和E3间的背景关系模糊时，支持时间顺序假设；事件E1和E3间的背景关系突出时，支持背景信息假设。据此可以得出：倒叙事件与前面事件间的背景关系突出时，其表征为E2-E3-E1-E4模式，背景关系模糊时，则为E1-E2-E3-E4模式。

英文摘要：

Time plays a central role in how people experience the world. In recent years, the question of how temporal information is processed during text comprehension has gained increasing interest in psycholinguistic research. Berry et al （2006） conducted their experiments with narratives containing flashbacks to test chronological hypothesis and background hypothesis. The results supported the chronological hypothesis exclusively. However, a flashback usually has a close thematic relationship to its preceding sentences. It seems plausible that a flashback is used at the exact point where the readers are meant to use it as background information. Would it be possible that the null effect in background hypothesis was due to the weak supplementary relationship between the flashback and the event described before？ In this study, moving window display technique was used to examine the rationality of chronological and background hypotheses. Participants were asked to read narratives describing 4 successive events in non-chronological order with E1 being mentioned in a flashback （E2-E3-E1-E4）. The experimental materials had two versions： the first one was the original passages from Berry Claus et al （2006）, and the second one highlighted the background relation between E1 and E3. The information about the time duration of E2 was manipulated, and the mental accessibility of E1 was tested in different methods at the end of each passage. The results consistently showed that the reading times for anaphoric sentences or the probe response latencies were significantly longer in the long-duration condition than in the short-duration condition when the background relationship was highlighted, which supported the background hypothesis. It suggests that the background relation between E1 and E3 is important for temporal representation of flashback event in narrative comprehension. If the supplementary function of flashbacks has enough been highlighted, participants would represent it in the form of E2-E3-E1-E4, otherwi
