Abstract

Various outcomes of language development have been reported among children with prelingual hearing impairment and successful hearing intervention may not always ensure appropriate language development in their future. Learning disability is the symptom that is most frequently combined with hearing impairment, accounting for nearly 10% of these children. The combination of developmental dyslexia, which is the main symptom of learning disabilities, may hamper their language development by affecting their reading/writing ability. However, the detection of developmental dyslexia during their preschool period is highly difficult regardless of the presence of hearing loss. Before evaluating hearing impaired children,37 normal-hearing children in preschool education were examined in terms of the cognitive abilities that are required for reading/writing abilities. The evaluations included Raben's colored progressive matrix test (RCPM), language developmental tests (S-S), Benton's visual memory tests, Phonological awareness tests and the Single Kana-moji writing test. S-S test and RCPM are useful for the exclusion of the cases with apparent developmental delays and reading comprehension did not correlate with their calendar age. However, drastic development of Kana-writing was observed after 60 moths of age.
