The present study investigated whether word-boundary information, provided by alternating colors (consistent or inconsistent with word-boundary information) in a Chinese sentence would facilitate the reading of second-language (L2) learners. Thirty-three Korean students were recruited in the eye-movement experiment. Relative to a baseline (i.e., mono-colors) condition, incorrect word segmentation produced closer fixation location toward the beginning of words, longer fixation duration, higher refixation rate, and slower reading speed. In contrast, word segmentation with alternating colors produced further fixation location toward the center of words, shorter fixation duration, lower refixation rate, and faster reading speed. These results indicate that L2 readers are capable of making use of word-boundary knowledge for saccade generation, which can result in a facilitation of reading efficiency.

交替颜色词有助于汉语第二语言学习者的阅读和眼球运动

本研究调查了在中文句子中通过交替颜色（与词边界信息一致或不一致）提供的词边界信息是否有助于第二语言（L2）学习者的阅读。眼动实验招募了33名韩国学生。相对于基线（即单色）条件，不正确的分词产生更接近单词开头的注视位置、更长的注视持续时间、更高的再注视率和更慢的阅读速度。相比之下，交替颜色的分词产生了更靠近单词中心的注视位置，更短的注视持续时间，更低的再注视率和更快的阅读速度。这些结果表明 L2 阅读器能够利用词边界知识进行扫视生成，
