摘　　要：采用EyeLink II眼动仪,以72名小学三年级学生为被试,通过三个实验来探讨词切分对初学者汉语句子阅读的影响。实验一设置四种空格呈现条件:正常的无空格条件、字间空格条件、词间空格条件和非词空格条件。实验二采用灰条标记作为字、词或非词的边界,使不同条件下句子的空间分布是一致的。实验三进一步操纵了学生的阅读技能。结果发现三个实验的结果趋势是一致的。小学三年级学生在阅读有词间空格的文本和正常的无空格文本一样容易。尽管词切分文本对阅读技能高和阅读技能低的学生来说一样容易,但非词空格呈现条件会对阅读技能低的学生产生更大的干扰作用。阅读技能低的学生在阅读过程中更依赖于文本的低水平视觉线索。文章最后讨论了词切分对建构中文阅读眼动控制模型的启示。Unlike English （and other alphabetic writing systems）,Chinese is written without spaces between successive characters and words.There is no obvious visual cue to demarcate the word except punctuation marks.Given this,it is intriguing how readers target saccades and how words are recognized in Chinese writing systems.Bai et al.（2008） monitored native Chinese readers＇ eye movements as they read text that did or did not demarkword boundary information.They found that inserting spaces between words （or highlighting word boundaries） did not facilitate reading Chinese,but more importantly,did not interfere with reading.Bai et al argued that facilitatory and inhibitory factors trade off against each other when words are clearly marked （in contrast to normal unspaced text presentation）.For the adults,the normal unspaced text will be extremely familiar,but word identification may be hindered due to poor word demarcation.In contrast,the word spaced text will be visually unfamiliar but word identification will be facilitated due to good word demarcation.The beginning readers have less experience in reading text without spaces,so the familiarity of the format is comparatively limited compared with the adults.We therefore predict that the interword spaced text may have a greater facilitatory effect for Chinese beginner readers than for adults.Three experiments were carried out.72 third graders participated in the research.Their eye movements were recorded with a SR Research EyeLink II eyetracker （sampling rate=500 Hz） that monitored the position of the right eye every two milliseconds.In experiment 1,four spacing conditions were included：normal unspaced condition;single character spaced condition （text with spaces between every character）;word spaced condition （text with spaces between words）;and nonword spaced condition （text with spaces between characters that yielded nonwords）.In experiment 2,highlighting was used to create analogous conditions：normal Chinese text,text with highlightin
