研究采用移動窗口范式,以雙字詞為掩蔽單元,探究了聾生中文閱讀知覺廣度與詞匯加工特點。結果發現:(1)聾生閱讀知覺廣度的左側范圍在1個雙字詞之外,右側范圍為1個雙字詞,健聽讀者閱讀知覺廣度為注視點左側1個雙字詞至右側1個雙字詞的范圍,可見聾生的閱讀知覺廣度在范圍大小和對稱性上不同于健聽讀者;(2)提示注視點右側詞匯邊界的移動窗口在平均注視時間、向右眼跳幅度上以相同趨勢影響兩組讀者,但對兩組讀者注視次數、回視次數的影響模式不同。由此可見,聾生讀者閱讀知覺廣度及詞匯加工有其獨特性特點。

With the moving window paradigm which shows the boundary of the right words to the fixation,the present study explored the characteristics of deaf Chinese readers in perceptual span and word processing when they were reading.It was found that:(1)For the deaf students,the left edge of the perceptual span extended more than one two-characters word,and the right edge extended one two-characters word,whereas for the hearing participants,the perceptual span extended one two-characters word to the left and right of fixation;(2)The moving window manipulations affected the two groups with the same trend on the mean fixation duration and the length of saccades toward the right,however,they affected the number of fixation and regression of the two groups differently.It revealed the uniqueness of deaf Chinese readers in perceptual span and word processing when they are reading.
