To determine whether preschool-age children with cochlear implants have age-appropriate phonological awareness and print knowledge and to examine the relationships of these skills with related speech and language abilities.
The sample comprised 24 children with cochlear implants (CIs) and 23 peers with normal hearing (NH), ages 36 to 60 months. Children's print knowledge, phonological awareness, language, speech production, and speech perception abilities were assessed.
For phonological awareness, the CI group's mean score fell within one standard deviation of the Test of Preschool Early Literacy's (Lonigan, Wagner, Torgesen, & Rashotte, 2007) normative sample mean but was more than one standard deviation below the NH group mean. The CI group's performance did not differ significantly from that of the NH group for print knowledge. For the CI group, phonological awareness and print knowledge were significantly correlated with language, speech production, and speech perception. Together these predictor variables accounted for 34% of variance in the CI group's phonological awareness but no significant variance in their print knowledge.
Children with CIs have the potential to develop age-appropriate early literacy skills by preschool age but are likely to lag behind their NH peers in phonological awareness. Intervention programs serving these children should target these skills with instruction and by facilitating speech and language development.
确定学龄前植入人工耳蜗的儿童是否具有适合年龄的语音意识和印刷知识,并研究这些技能与相关言语和语言能力的关系。
样本包括 24 名植入人工耳蜗(CI)的儿童和 23 名正常听力(NH)的同龄儿童,年龄在 36 至 60 个月之间。评估了儿童的印刷知识、语音意识、语言、言语产生和言语感知能力。
在语音意识方面,CI 组的平均得分在 Lonigan 等人(2007 年)的《学前早期读写能力测试》(Test of Preschool Early Literacy)的常模样本均值的一个标准差范围内,但低于 NH 组均值一个标准差以上。CI 组与 NH 组在印刷知识方面的表现没有显著差异。对于 CI 组,语音意识和印刷知识与语言、言语产生和言语感知显著相关。这些预测变量共同解释了 CI 组语音意识的 34%,但对其印刷知识没有显著的解释。
植入人工耳蜗的儿童有潜力在学龄前发展出适合年龄的早期读写技能,但在语音意识方面可能落后于 NH 同龄人。为这些儿童服务的干预计划应该通过指导和促进言语和语言发展来针对这些技能。
