Increasing intercharacter spacing reduces the transposed-character effect in Chinese reading: Evidence from eye movements

Abstract

ABSTRACT Spacing is a very important visual cue in alphabetic languages as well as other languages, such as Chinese, which has no special interword spacing but has equal intercharacter spacing. Studies have shown that spacing has a significant effect on letter/character identity or position processing. However, whether spacing modulates the transposed-letter/-character effect remains unknown. This study conducted an eye-movement experiment using the boundary paradigm to explore whether increasing intercharacter spacing affected the transposed-character effect in Chinese reading. The results indicate that Chinese readers have flexible adjustment strategies for intercharacter spacing and that there is an obvious transposed-character effect. Crucially, increasing intercharacter spacing by three points resulted in stricter character position processing as compared with identity processing, thus reducing the transposed-character effect. Our findings are consistent with models in which visual elements comprise an important factor in the transposed-letter/-character effect, while the existence of the transposed-character effect suggests that the orthographic abstract component is also relevant.
