1)人工耳蜗植入（CI）手术前在成人中获得的阅读效率评分（单词阅读效率测试，第2版，TOWRE-2）将预测手术后6个月的语音识别结果; 2）通过植入前至植入后的阅读效率测量，人工耳蜗植入将导致语言处理的改善。成年CI用户在语音识别结果中显示出显着的变化。“自上而下”的处理-使用认知资源，使退化的语音的意义-有助于语音识别能力的CI用户。词汇和语音处理的效率是一个很少受到关注的领域。在这项研究中，视觉测量的字和非字阅读效率-依赖于词汇和语音处理，分别-被调查的能力，以预测CI语音识别结果，以及确定植入后的任何改进。24名语言失聪后的成年CI候选人在TOWRE-2上进行了术前和CI后6个月的测试。CI后六个月的语音识别措施也在一组单词和句子识别中进行了评估。术前非文字阅读评分对句子识别结果有中度预测作用，但真实的文字阅读评分则没有;文字识别评分也没有预测作用。CI后6个月，无论是单词还是非单词阅读效率均无改善。语音处理作为衡量的TOWRE-2非词阅读预测到中等程度的6个月的句子识别结果在成年CI用户。植入后阅读效率没有改善，尽管这可能是由于CI使用的持续时间相对较短。
1) Scores of reading efficiency (the Test of Word Reading Efficiency, 2nd Edition, TOWRE-2) obtained in adults prior to cochlear implant (CI) surgery will be predictive of speech recognition outcomes 6 months after surgery; and 2) Cochlear implantation will lead to improvements in language processing as measured through reading efficiency from pre- to post-implantation. Adult CI users display remarkable variability in speech recognition outcomes. “Top-down” processing – the use of cognitive resources to make sense of degraded speech – contributes to speech recognition abilities in CI users. One area that has received little attention is the efficiency of lexical and phonological processing. In this study, a visual measure of word and nonword reading efficiency – relying upon lexical and phonological processing, respectively – was investigated for its ability to predict CI speech recognition outcomes, as well as to identify any improvements after implantation. Twenty-four post-lingually deaf adult CI candidates were tested on the TOWRE-2 pre-operatively and again 6 months post-CI. Six-month post-CI speech recognition measures were also assessed across a battery of word and sentence recognition. Pre-operative nonword reading scores were moderately predictive of sentence recognition outcomes, but real word reading scores were not; word recognition scores were not predicted by either. No 6-month post-CI improvement was demonstrated in either word or nonword reading efficiency. Phonological processing as measured by the TOWRE-2 nonword reading predicts to a moderate degree 6-month sentence recognition outcomes in adult CI users. Reading efficiency did not improve after implantation, though this could be due to the relatively short duration of CI use.
