We assessed profoundly deaf children with cochlear implants (CIs) (N = 24) and age-matched normal-hearing children (N = 31) on several nonverbal cognition measures: motor sequencing, tactile discrimination, response inhibition, visual-motor integration, and visual-spatial processing. The results revealed that the children with CIs showed disturbances solely on motor sequencing and that performance on this task was significantly correlated with scores on the Clinical Evaluation of Language Fundamentals, 4th Edition (CELF–4). These findings suggest that a period of auditory deprivation before cochlear implantation affects motor sequencing skills, which in turn may mediate the language delays displayed by some deaf children with CIs.

耳蜗植入后聋童的非语言认知：运动序列障碍介导语言延迟

我们评估了植入人工耳蜗 (CI) 的重度聋儿童 (N = 24) 和年龄匹配的正常听力儿童 (N = 31) 的几种非语言认知测量：运动排序、触觉辨别、反应抑制、视觉-运动整合和视觉空间处理。结果显示，患有 CI 的儿童仅在运动排序方面表现出障碍，并且该任务的表现与语言基础临床评估第 4 版 (CELF-4) 的分数显着相关。这些发现表明，在人工耳蜗植入之前的一段听觉剥夺会影响运动排序技能，这反过来可能会介导一些患有 CI 的聋童表现出的语言延迟。
