本研究的目的是：（a）确定年龄对儿童人工耳蜗植入者频谱调制检测（SMD）能力的影响，并将其年龄效应与正常听力（TH）同龄人进行比较;（B）确定与SMD能力相关的人口学、认知和听力学因素;和（c）以确定独特的贡献SMD的能力段和超段言语知觉performance.MethodA共104名儿童CI收件人和38 TH同行（年龄6-11岁）完成了测试SMD。CI接受者完成了节段性测试（例如，噪声中的单词识别以及安静中的元音和辅音）和超音段（例如，谈话者辨别力、压力辨别力和情绪识别）知觉、非语言智力和工作记忆。回归分析被用来检查组和年龄的影响，对自我纠正SMD评分。对于CI组，人口，听力学，和认知变量的SMD性能和SMD对语音感知的影响进行了examined.ResultsThe TH组的SMD表现显着优于CI组。随着年龄的增长，两组的表现都更好。CI组SMD表现的重要预测因素是年龄和非语言智力。SMD性能预测的显着差异，在节段和超节段感知。SMD性能预测的方差是近两倍的超节段比节段perception.ConclusionsChildren在CI组，平均得分低于他们的TH同龄人。SMD随年龄增长的改善斜率在两组之间没有差异。非语言智力对CI受试者SMD表现的显著影响表明，任务中固有的困难会影响结果。SMD能力预测言语知觉分数，在超分段言语知觉中的作用比在分段言语知觉中更突出。SMD能力可以提供一个有用的非语言工具来预测言语感知的好处，根据年龄和认知功能进行谨慎的解释。
PurposeThe aims of this study were, for pediatric cochlear implant (CI) recipients, (a) to determine the effect of age on their spectral modulation detection (SMD) ability and compare their age effect to that of their typically hearing (TH) peers; (b) to identify demographic, cognitive, and audiological factors associated with SMD ability; and (c) to determine the unique contribution of SMD ability to segmental and suprasegmental speech perception performance.MethodA total of 104 pediatric CI recipients and 38 TH peers (ages 6–11 years) completed a test of SMD. CI recipients completed tests of segmental (e.g., word recognition in noise and vowels and consonants in quiet) and suprasegmental (e.g., talker discrimination, stress discrimination, and emotion identification) perception, nonverbal intelligence, and working memory. Regressions analyses were used to examine the effects of group and age on percent-correct SMD scores. For the CI group, the effects of demographic, audiological, and cognitive variables on SMD performance and the effects of SMD on speech perception were examined.ResultsThe TH group performed significantly better than the CI group on SMD. Both groups showed better performance with increasing age. Significant predictors of SMD performance for the CI group were age and nonverbal intelligence. SMD performance predicted significant variance in segmental and suprasegmental perception. The variance predicted by SMD performance was nearly double for suprasegmental than for segmental perception.ConclusionsChildren in the CI group, on average, scored lower than their TH peers. The slopes of improvement in SMD with age did not differ between the groups. The significant effect of nonverbal intelligence on SMD performance in CI recipients indicates that difficulties inherent in the task affect outcomes. SMD ability predicted speech perception scores, with a more prominent role in suprasegmental than in segmental speech perception. SMD ability may provide a useful nonlinguistic tool for predicting speech perception benefit, with cautious interpretation based on age and cognitive function.
