中文摘要：

运用动窗技术探讨中文阅读中的边界效应及其消除的条件，包括3个实验。实验一探讨中文阅读中是否存在边界效应，结果发现，边界效应同样存在于中文阅读中；实验二、三探讨时间切分标记能否消除边界效应以及消除的条件，结果发现，只有当切分标记表示的时间在前一事件持续的时间跨度外时才能消除边界效应，如果切分标记表示的时间仍在前一事件持续的时间跨度内，则不能消除边界效应，本研究称此为事件持续效应。从本研究结果中可以得出，时间切分标记降低了主题转换句子所需要的认知加工能量。

英文摘要：

The boundary effect refers to the phenomenon of the reading time for the first sentence of a new discourse unit being longer than the reading time for any other sentence. This phenomenon was fh-st discovered by Haberland and his colleagues （Haberland K F, Berian C ＆ Sandson J, 1980）. Other studies have also found evidences for this effect （Lorch R F, Lorch E P ＆ Matthews, 1985; Bestgen Y ＆ Vonk W, 2000）. When reading, readers first try to integrate the new information with preceding information that has just been read and that still remains in the working memory. When a reader experiences difficulty in integrating new information with the preceding information, he/she will conclude that the topic has been changed and that a new mental representation needs to be constructed to lay an integral foundation for the incoming information. To maintain continuity, readers have to reinstate the preceding concept or make coherent inferences and each of these processes increases their cognitive load; at the same time, construction of a new mental representation also needs extra cognitive resources. Therefore, reading speed slows down, and reading time increases. Bestgen and his colleagues explored whether segmentation markers could eliminate this effect. Their results showed that a segmentation marker, for example, ＂around two o＇clock,＂ could successfully eliminate the boundary effect. However, the segmentation marker in their study did not show the temporal relationship between the markers and the event preceding, In our opinion, when the markers are within the duration time of the event preceding them, boundary effect will be observed; however, when they are not within the duration time of the event preceding them, the boundary effect will be eliminated. This phenomenon is referred to as the event duration effect. In the present study, three experiments were conducted to examine whether the boundary and event duration effects could be observed in Chinese text reading, A moving window technique was used
