中文摘要：

空格作为英语等大多数拼音文字阅读中的词边界信息，能帮助读者成功地从文本的一连串的字母中切分出词，促进了词汇的习得和识别。然而在中文里没有明确的词边界信息，那么提供词边界信息（即加入空格）能否促进中文词汇识别或帮助读者学习新词？本文将从空格对成人、儿童和留学生在阅读中眼动控制的影响来回顾和总结词边界信息在中文词汇识别与学习中的作用。在此基础上，提出对建立汉字与词汇识别模型、眼动控制模型以及对指导汉语教学工作的启示。

英文摘要：

Word spacing is an important indicator of word boundary in most alphabetic writing system such as English, as it can not only help readers to successfully segment each word from successive character strings in text but also help readers to acquire and recognise word. However, there is no clear word boundary information in Chinese reading, it is interesting to investigate whether it can facilitate word recognition or help readers to learn new word when providing word boundary information （i.e. word space） in Chinese reading. We reviewed the effect of word spacing on eye movement control during Chinese reading in adults, children and second language learners of Chinese. Based on the current findings reviewed in this paper, we provided some implications for constructing models of character and word recognition and eye movement control in Chinese reading, as well as prompting Chinese teaching proficiency.
