Eye-movement-contingent display changes were used to control the visibility of characters during the reading of Chinese text. Characters outside a window of legible text were masked by dissimilar characters, and effects of viewing constraints were ascertained in several oculomotor measures. The results revealed an asymmetric perceptual span that extended 1 character to the left of the fixated character and 3 characters to its right. The size of right-directed saccades extended across 2 to 2 1/2 character spaces, indicating that the perceptual spans of successive fixations overlapped slightly and that some linguistic information was integrated across fixations. The relatively small spatial overlap of successive spans appears to reflect a text-specific process. However, the results also revealed substantial similarities in the coding of morphographic Chinese and alphabetic English texts, indicating that text-specific coding routines are subordinated to general coding principles.
在阅读中文文本时，采用眼动视情显示变化来控制字符的可见性。在清晰文本窗口之外的字符会被不同的字符遮挡，并且通过多种眼动测量方式确定了视觉限制的影响。结果显示出一种不对称的感知跨度，该跨度在注视字符左侧延伸1个字符，在其右侧延伸3个字符。向右扫视的幅度跨越2到2.5个字符空间，这表明连续注视的感知跨度略有重叠，并且一些语言信息在注视之间得到了整合。连续跨度相对较小的空间重叠似乎反映了一个特定于文本的过程。然而，结果还揭示了中文象形文字文本和英文拼音文本在编码方面存在大量相似之处，这表明特定于文本的编码程序从属于一般编码原则。
