早期（8-10岁）植入人工耳蜗的儿童的快速语音处理技能，通过非单词重复性能来衡量，将预测他们8年后（16-18岁）的语言发展。这种核心处理能力也将与两个测试年龄段的语言同步测量相关。了解小儿人工耳蜗使用者广泛表现的原因目前构成了该领域临床和研究进展的主要障碍。对儿童神经认知能力的研究，如工作记忆能力和口头复述速度，以及传统的人口统计变量，表明这些基本技能在决定结果中起着关键作用。在这里，我们调查的影响，快速语音处理能力，这是关键的口语使用，人工耳蜗植入儿童。52名植入人工耳蜗的聋儿在相隔8年的两次测试中完成了14项语言、神经认知和非单词重复技能的临床和研究测量。在两次测试中，非词重复任务的表现与并发语言能力显着相关。重要的是，8-10岁时的非单词重复准确性也显著预测了16-18岁时在广泛领域的语言能力测量中的表现，从语音清晰度到噪音中的句子识别。这些关系是显着的，即使在其他神经认知措施的控制。人工耳蜗植入儿童的早期非单词重复表现预测了以后的语言发展，因此可以识别出那些预后不良的高风险儿童。
The rapid phonological processing skills of children with cochlear implants early in life (ages 8–10), as measured by nonword repetition performance, will predict their language development eight years later (ages 16–18). This core processing ability will also correlate with concurrent measures of language at both ages of testing. Understanding the causes of the wide range of performance in pediatric cochlear implant users currently constitutes a major barrier to clinical and research progress in the field. Research into children’s neurocognitive abilities such as working memory capacity and verbal rehearsal speed, in addition to conventional demographic variables, has shown that these foundational skills play a key role in determining outcomes. Here we investigate the impact of rapid phonological processing, an ability which is critical in spoken language use, for children with cochlear implants. 52 deaf children with cochlear implants completed a battery of 14 clinical and research measures of language, neurocognitive, and nonword repetition skills in two testing sessions 8 years apart. Performance on the nonword repetition task at both testing sessions correlated significantly with concurrent language abilities. Importantly, nonword repetition accuracy at age 8–10 also significantly predicted performance on measures of language ability at age 16–18 in a wide range of domains, from speech intelligibility to sentence recognition in noise. These relations were significant even when other neurocognitive measures were controlled. Early nonword repetition performance in children with cochlear implants predicts later language development, and therefore may identify those children at high risk for poor outcomes.
