Studies on specific language impairment (SLI) in French have identified specific aspects of morphosyntax as particularly vulnerable. However, a cohesive picture of relative strengths and weaknesses characterizing SLI in French has not been established. In light of normative data showing low morphological error rates in the spontaneous language of French-speaking preschoolers, the relative prominence of such errors in SLI in young children was questioned.
Spontaneous language samples were collected from 12 French-speaking preschool-age children with SLI, as well as 12 children with normal language development matched on age and 12 children with normal language development matched on mean length of utterance. Language samples were analyzed for length of utterance; lexical diversity and composition; diversity of grammatical morphology and morphological errors, including verb finiteness; subject omission; and object clitics.
Children with SLI scored lower than age-matched children on all of these measures but similarly to the mean length of utterance-matched controls. Errors in grammatical morphology were very infrequent in all groups, with no significant group differences.
The results indicate that the spontaneous language of French-speaking children with SLI in the preschool age range is characterized primarily by a generalized language impairment and that morphological deficits do not stand out as an area of particular vulnerability, in contrast with the pattern found in English for this age group.
针对法语特定语言障碍(SLI)的研究已确定形态句法的特定方面特别容易受到影响。然而,法语SLI相对优势和劣势的连贯图景尚未建立。鉴于规范数据显示说法语的学龄前儿童自发语言中的形态错误率较低,幼儿SLI中此类错误的相对突出性受到质疑。
从12名说法语的患有SLI的学龄前儿童、12名年龄匹配的语言发育正常儿童以及12名话语平均长度匹配的语言发育正常儿童中收集自发语言样本。分析语言样本的话语长度、词汇多样性和构成、语法形态多样性和形态错误,包括动词限定形式、主语省略和宾语代词。
患有SLI的儿童在所有这些指标上的得分均低于年龄匹配的儿童,但与话语平均长度匹配的对照组相似。所有组中语法形态错误都很少见,组间无显著差异。
结果表明,学龄前说法语的患有SLI的儿童的自发语言主要表现为广泛性语言障碍,与该年龄组英语中发现的模式相反,形态缺陷并不突出为特别易受影响的领域。
