Present study investigated how character order encoding influence on word processing in Chinese reading. In the Experiment 1,using boundary paradigm, we manipulated the preview type of target words(preview identical word & preview transposed character noword). The results have showed that preview transposed character noword influenced the eye movement data, but it did not interrupt word frequency effects. Using boundary paradigm, there were also two display type of target word in Experiment 2:participants preview and fixate an identical word as the control, and participants preview the target word but when the eye cross the boundary the word was changed into transposed character noword. The results have shown that this manipulation influenced the eye movement data and eliminated the word frequency effect. The results of these two experiments indicted that both character order encoding in preview and fixation phrases interrupted word identification, and that word processing in preview phrase was not strictly depending on character order encoding, however the dependence become more strictly in fixation phrase.
