The aim of this study was to investigate how age at cochlear implantation (CI) and age at exposure to Cued Speech (CS, Manual system that resolves the ambiguity inherent lipreading) could impact literacy skills in deaf children. Ninety deaf children fitted with CI (early vs late) and exposed to CS (early vs late) from primary schools (from Grade 2 to Grade 5) took part in this study. Five literacy skills were assessed: phonological skills through phoneme deletion, reading (decoding and sentence comprehension), word spelling and vocabulary. The results showed that both age at CI and age at first exposure to CS had some influence on literacy skills but there was no interaction between these factors. This implies that the positive effects of age at CI, especially on all literacy skills in the younger children, were not strengthened by age at exposure to CS.
