首词素位置概率信息未参与汉语阅读的词切分：基于副中央凹加工的证据

本研究采用边界范式，考察汉语阅读中读者是否在副中央凹处利用首词素的位置概率信息进行词切分和词识别。采用2（首词素位置概率：高、低）×２（预视类型：相同预视、假字预视）的被试内实验设计，以双字词为目标词，记录大学生阅读句子时的眼动轨迹。结果发现，在跳读率和第一遍阅读的眼动指标中，被试在高、低首词素位置概率条件中获得的预视效益量无显著差异。该结果表明，读者并未在副中央凹处加工首词素的位置概率信息。结合前期研究推断，首词素位置概率信息没有作用于汉语阅读的词切分和词识别。

Initial Character Positional Probability Does Not Influence Word Segmentation in Chinese Reading: Evidence from Parafoveal Processing

We manipulated the initial character positional probability of two-character word and preview type using boundary paradigm, in order to answer whether Chinese readers are sensitive to the information of word initial character’s positional probability during word segmentation and word identification in natural Chinese reading. Two-character words were selected as target words. The initial character’s positional probability was manipulated as being either high or low, and the final character was kept identical across the two conditions. We recorded adults’ eye movements when they read sentences containing these words. The results showed that preview benefits did not differ in the high-probability and low-probability conditions for skipping probability and the measures of first pass reading, demonstrating that Chinese readiness did not use word initial character positional probability in parafovea for word segmentation and word identification in Chinese reading.
