Learning to write words may strengthen orthographic representations and thus support word-specific recognition processes. This hypothesis applies especially to Chinese because its writing system encourages character-specific recognition that depends on accurate representation of orthographic form. We report 2 studies that test this hypothesis in adult learners of Chinese. In those studies, the researchers 1st compared the effects of an online writing tutor that included character handwriting with an instructional tutor that included reading only. The writing condition led to better performance on word recognition and on character-meaning links but not on the character-phonology link. In the 2nd experiment, we added an alphabetic (Pinyin) typing tutor to strengthen the phonology link and to control for manual motor activity during instruction. This experiment replicated the effects of writing on word recognition and character-meaning links, whereas alphabetic (Pinyin) typing supported only phonological representations and the character-phonology link. Theoretically, the studies suggest constituent-specific effects: writing on orthography and alphabetic coding on phonology. We suggest the mechanism for the writing effect is the refinement of visual-spatial information needed for character recognition and the addition of a sensory-motor memory that accompanies writing. The practical implication is that an integration of character handwriting and Pinyin typing promotes learning to read Chinese in a second language learning context. (Contains 2 tables and 5 figures.)
