The narrative skills of children with cochlear implants (CIs) are fragile, but the factors at play and whether these difficulties could be similar to those detected in language impairment are not clear. The present study aims to assess, at the microstructural level, narrative skills, comparing children with CIs with children with Developmental Language Disorder (DLD) or Typical Development (TD). Furthermore, the relationship between verbal (lexical and morphosyntactic) comprehension and narrative skills across groups is investigated.
The narratives of 19 children with CIs (M = 62.42 months, SD = 6.83), 13 children with DLD (M = 65.38 months, SD = 4.27), and 18 preschool children with TD (M = 63.67 months, SD = 4.31) were assessed in a standardized task. Articles, prepositions, pronouns, gender and number agreement, accuracy in the use of verbs, and number of arguments in each sentence were analysed. Lexical and morphosyntactic comprehension were also assessed. Performance was compared across groups using ANOVAs or Kruskal-Wallis tests. The role of lexical and morphosyntactic comprehension in predicting each morphological and syntactic element in the narrative task was examined using linear regressions.
Data analysis showed that both children with CIs and DLD had fragilities in narration, both in the morphological and syntactic components. Although some differences between children with CIs and those with DLD emerged in descriptive analyses, these were not statistically significant. Regressions showed that morphosyntactic comprehension predicted the number of pronouns produced only in the TD group.
The scarce differences between CI and DLD groups and the absence of an effect of morphosyntactic comprehension on pronoun production may be due to their low production of these elements in the narrative task and/or to a difficulty in managing pronouns in an expressive task regardless of their ability to comprehend them. Potential implications of these results are discussed.
植入人工耳蜗的儿童的叙事能力很脆弱,但目前尚不清楚起作用的因素,以及这些困难是否与语言障碍中检测到的困难相似。本研究旨在在微观结构层面上评估儿童的叙事能力,将植入人工耳蜗的儿童与有发育性语言障碍(DLD)或典型发育(TD)的儿童进行比较。此外,还研究了各组之间言语(词汇和形态句法)理解与叙事能力之间的关系。
使用标准化任务评估了 19 名植入人工耳蜗的儿童(M = 62.42 个月,SD = 6.83)、13 名有 DLD 的儿童(M = 65.38 个月,SD = 4.27)和 18 名有 TD 的学龄前儿童(M = 63.67 个月,SD = 4.31)的叙事能力。分析了冠词、介词、代词、性别和数一致、动词使用准确性以及每个句子中的参数数量。还评估了词汇和形态句法理解。使用 ANOVA 或 Kruskal-Wallis 检验比较各组之间的表现。使用线性回归检验词汇和形态句法理解在预测叙事任务中每个形态和句法元素中的作用。
数据分析表明,植入人工耳蜗的儿童和有 DLD 的儿童在叙述中都存在困难,包括形态和句法两个方面。虽然在描述性分析中发现植入人工耳蜗的儿童和有 DLD 的儿童之间存在一些差异,但这些差异在统计学上并不显著。回归分析表明,形态句法理解仅能预测 TD 组中代词的使用数量。
植入人工耳蜗的儿童和 DLD 组之间差异较小,形态句法理解对代词产生的影响不显著,这可能是由于他们在叙事任务中代词使用量较少,或者由于他们在表达任务中难以处理代词,而与他们的理解能力无关。讨论了这些结果的潜在影响。
