This study examined the associations of vocabulary and phonological and orthographic awareness with Hangul word reading in Korean children, aged between 7 and 10 years, who were deaf and hard of hearing (DHH) and children with typical hearing (TH). The participants were 24 children with hearing aids (HAs), 24 children with cochlear implants (CIs), and 24 TH children in Korea. The three groups were matched for chronological age, vocabulary age, and nonverbal intelligence. Results showed that there were no differences between children with CIs and those with HAs in reading fluency and cognitive skills, except word-reading accuracy, whereas children with CIs and HAs were delayed in all measures compared with their TH peers. Regression analyses showed that syllable and phoneme awareness uniquely explained word-reading accuracy in children with DHH and those with TH. However, word-reading fluency was uniquely explained by syllable awareness in the DHH children and by vocabulary and orthographic awareness in the TH children. These results suggest that DHH and TH children in Korea rely on phonological awareness for Korean word recognition. However, DHH and TH Korean children tend to use different strategies based on sublexical versus lexical information, respectively, to read Korean words fluently.
本研究调查了7至10岁韩国聋哑及重听（DHH）儿童和听力正常（TH）儿童的词汇、语音及正字法意识与韩文单词阅读之间的关联。参与者包括24名佩戴助听器（HA）的儿童、24名接受人工耳蜗植入（CI）的儿童以及24名韩国听力正常儿童。三组在实际年龄、词汇年龄和非语言智力方面进行了匹配。结果显示，除单词阅读准确性外，接受人工耳蜗植入的儿童与佩戴助听器的儿童在阅读流畅性和认知技能方面并无差异，然而，与听力正常的同龄人相比，接受人工耳蜗植入和佩戴助听器的儿童在所有测量指标上均有所延迟。回归分析表明，音节和音素意识是DHH儿童和TH儿童单词阅读准确性的唯一解释因素。然而，DHH儿童的单词阅读流畅性唯一由音节意识解释，而TH儿童则由词汇和正字法意识解释。这些结果表明，韩国的DHH儿童和TH儿童在识别韩文单词时依赖语音意识。然而，韩国的DHH儿童和TH儿童在流畅阅读韩文单词时，往往分别基于次词汇信息和词汇信息使用不同的策略。
