由于中文的书写没有拼写单词的边界(即空格)，因此不清楚扫视目标是根据字符还是单词来选择的，以及扫视是针对单词的开头还是中心。在这里，我们报道了一个实验，30名中国读者阅读150个句子，同时监测他们的眼动。在单一注视的情况下，他们表现出强烈的注视词中心的倾向，而在多重注视的情况下，他们表现出强烈的注视词首的倾向。与间隔字母不同，最初的注视落在单词末尾的可能性并不比单词中心的初始注视更大。此外，在两次注视的情况下，单次注视比第一次注视更短，这与罗马文字中的情况相反。我们建议中国读者动态地选择单词的开头或中心作为扫视目标，这取决于对旁中凹单词边界分割的失败或成功。
As Chinese is written without orthographical word boundaries (i.e., spaces), it is unclear whether saccade targets are selected on the basis of characters or words and whether saccades are aimed at the beginning or the centre of words. Here, we report an experiment where 30 Chinese readers read 150 sentences while their eye movements were monitored. They exhibited a strong tendency to fixate at the word centre in single-fixation cases and at the word beginning in multiple-fixation cases. Different from spaced alphabetic script, initial fixations falling at the end of words were no more likely to be followed by a refixation than initial fixations at word centre. Further, single fixations were shorter than first fixations in two-fixation cases, which is opposite to what is found in Roman script. We propose that Chinese readers dynamically select the beginning or centre of words as saccade targets depending on failure or success with segmentation of parafoveal word boundaries.
