本研究采用眼动记录的方法，考察了被试理解层次分隔歧义句时，作为书面韵律边界的逗号起到的作用，以及逗号与语境信息间的交互作用。实验通过操纵逗号的位置，变化歧义句的句义；通过操纵语境内容，变化语境偏向与逗号解歧方向的一致性。结果发现，逗号做为书面的韵律边界促进了句子的加工。当有书面韵律边界为句子解歧时，被试更依赖于韵律边界。语境信息与书面韵律边界的交互作用发生于句子加工晚期。

The present study was designed to investigate effects of Chinese punctuations on the comprehension of ambiguous sentence caused by different Layers, and the interaction between punctuations and the context. Experiments varied the meaning of the ambiguous sentencs according to the location of the comma, and the Consistency between the context and the meaning explained by the comma varied according to the context. The result showed: the commas in Chinese sentences could promote the processing of the reading. When there was a comma, subjects would more relay the punctuations on the understanding.
