In 2 experiments, we tested the prediction that reading is more efficient when characters belonging to a word are presented simultaneously than when they are not in Chinese reading using a novel variation of the moving window paradigm (McConkie & Rayner, 1975). In Experiment 1, we found that reading was slowed down when Chinese readers could not see characters belonging to a word simultaneously compared to when they could do so. In Experiment 2, when Chinese readers could choose whether the 2 characters in the moving window contained a word or 2 characters that did not constitute a word, they had a clear tendency to look at 2 characters belonging to a word simultaneously. The results of the current study provide strong evidence that character processing is affected by word knowledge and the processing of other characters belonging to the same word in Chinese reading, and add to a growing body of evidence demonstrating that words do have psychological reality for Chinese readers. The results also suggest that the eye movement control strategy of Chinese readers is rather flexible in that it can be adjusted online to modify the characteristics of the window.
