The present study aimed to analyse the narrative competence of a group of Italian children with a bilateral cochlear implant (CI) implanted before 30 months of age. Participants were ten children with CI (aged from 42 to 83 months) and two control groups of typically hearing children one-to-one paired by sex, non-verbal reasoning, and chronological or hearing age. A story generation task, specifically developed to assess narrative skills in children (i.e., the Narrative Competence Task) was used to evaluate both macrostructural and microstructural features of the children's narratives. Results showed that children with CI presented only one significant difference in the macrostructural aspects of narratives compared to typically hearing children matched by hearing age, specifically in the higher number of events told. In addition, concerning microstructural features, the only statistically significant difference was a lower lexical variety in the narratives produced by children with CI than in those produced by typically hearing children matched by chronological age. Both macrostructural and microstructural indices appeared to be related to the hearing age of children with CI. Early CI appeared to play a crucial role in the acquisition of a complex area of language development, as narrative competence.
本研究旨在分析一组在 30 个月前植入双侧人工耳蜗(CI)的意大利儿童的叙事能力。参与者包括 10 名植入 CI 的儿童(年龄在 42 至 83 个月之间)和两个对照组的正常听力儿童,按性别、非言语推理和年龄或听力年龄进行一对一配对。使用专门开发的用于评估儿童叙事技能的故事生成任务(即叙事能力任务)评估了儿童叙事的宏观结构和微观结构特征。结果表明,与按听力年龄匹配的正常听力儿童相比,植入 CI 的儿童在叙事的宏观结构方面仅存在一个显著差异,具体表现为讲述的事件数量更多。此外,在微观结构特征方面,植入 CI 的儿童所产生的叙事的词汇多样性明显低于按年龄匹配的正常听力儿童。宏观结构和微观结构指数似乎都与植入 CI 的儿童的听力年龄有关。早期 CI 似乎在儿童叙事能力等复杂语言发展领域的获取中起着至关重要的作用。
