Why Does Rapid Naming Predict Chinese Word Reading?

Rapid automatized naming (RAN) robustly predicts early reading abilities across languages, but its underlying mechanism remains unclear. This study found that RAN associated significantly with processing speed but not with phonological awareness or orthographic knowledge in 89 Hong Kong Chinese second-graders. RAN overlaps more with processing speed (18% of individual variation) in predicting word reading fluency, than with phonological (4%) or orthographic awareness (3%), suggesting that processing speed contributed more strongly to the RAN-reading fluency relation in Chinese. Nonetheless, RAN remained significant in predicting Chinese word-level reading fluency when all other cognitive tasks were taken into account, suggesting that no single construct can fully explain RAN’s relation to reading, but that multiple components influence this relation. Moreover, when reading abilities in second language English were considered, the association between RAN and word reading fluency was marginally stronger in Chinese than in English. Implications for mechanisms underlying the RAN-reading relation are discussed.postprin

Phonological representations and early literacy in Chinese

Phonological processing skills predict early reading development, but what underlies developing phonological processing skills? Phonological representations of 140 native Cantonese-speaking Chinese children (age 4–10) were assessed with speech gating, mispronunciation detection, and nonword repetition tasks; their nonverbal IQ, reading, and phonological processing were assessed with standard tests. Results indicated that even without explicit script-sound correspondence at the phonemic level in Chinese orthography, young Chinese speakers developed representations segmented at this level, and such representations were more fine-grained for older children. Further, the quality of kindergarteners’ phonological representations (specified by sensitivity to mispronunciation in lexical judgment) significantly predicted their emergent reading abilities, and this relation was fully mediated by phonological processing skills, with rapid naming showing the strongest mediation effect. Such mediation was no longer found with the primary-school sample, suggesting plausible developmental changes in the relations between phonological representations, phonological processing, and reading during early reading development.postprin
