Interword spacing in Chinese text layout.
Three experiments using Chinese text were conducted to investigate word spacing and its effect on reading performance. In Exp. 1, a sonogram detector was used to analyze interword and intercharacter (within a word) time intervals from text read aloud by professional TV broadcasters versus college graduates. The results showed interword intervals were significantly longer than intercharacter intervals, indicating that interword spacing has psychological reality in speech. Exp. 2 examined the effect on reading performance due to separating the characters that compose a word. Separating the characters of a word did not decrease reading accuracy but did result in significantly longer reading times. Exp. 3 explored the effect of word spacing in Chinese sentences on reading performance. Analysis showed that word spacing did not affect reading accuracy, but half character and whole-character spacing significantly reduced reading time. The results of the present study suggest that word spacing in Chinese text layout enhances reading performance. Word spacing may help the reader to segment more quickly a string of characters into words and reduce the likelihood of misinterpretation. Also, ambiguity of sentence structure severely degraded reading accuracy. The implications of the results for word spacing design in Chinese text are discussed.
