Unlike in English, the Chinese printing and writing systems usually do not respect a word boundary when they split lines; thus, characters belonging to a word can be on two different lines. In this study, we examined whether dividing a word across two lines interferes with Chinese reading and found that reading times were shorter when characters belonging to a word were on a single line rather than on adjacent lines. Eye movement data indicated that gaze durations in a region around the word boundary were longer and fixations were closer to the beginnings and ends of the lines when words were split across lines. These results suggest that words are processed as a whole in Chinese reading, so that word boundaries should be respected when deciding how to split lines in the Chinese writing system. They also suggest that the length of return sweeps in reading can be cognitively guided.
