Extended optional use of direct object clitic pronouns (e.g., la in Paula la vede ["Paula sees her"]) appears to be a clinical marker for specific language impairment (SLI) in Italian. In this study, we examined whether sentence production demands might influence the degree to which Italian-speaking children with SLI produced clitics.
Preschool-age children with SLI ( n = 15) and 2 groups of younger typically developing children ( n = 15 each) participated. Production demands were varied through use of a syntactic priming task.
The children with SLI were more likely than the comparison children to omit the clitic in a control condition in which they had to describe a target picture without the benefit of a preceding sentence prime. The children with SLI were also more likely to describe target pictures using a default clitic or a clitic that had appeared in the preceding prime sentence but was inappropriate for the target.
The findings suggest that children with SLI have difficulty generating a sentence containing a grammatical slot for a clitic when production demands are increased, and when they succeed in generating such a sentence, they often cannot at the same time retrieve the appropriate clitic form.
直接宾语代词(例如,Paula la vede [“Paula 看见她”中的 la])的扩展可选使用似乎是意大利语特定语言损伤(SLI)的临床标志物。在这项研究中,我们研究了句子生成需求是否会影响 SLI 意大利语儿童产生代词的程度。
参与研究的有 15 名 SLI 学龄前儿童和两组年龄较小的正常发育儿童(每组 15 名)。通过使用句法启动任务来改变生成需求。
与对照组相比,在没有前句启动的情况下描述目标图片时,SLI 儿童更有可能省略代词。在对照组中,他们更有可能使用默认代词或在前一句中出现但不适合目标的代词来描述目标图片。
这些发现表明,当生成需求增加时,患有 SLI 的儿童很难生成包含代词语法槽的句子,并且当他们成功生成这样的句子时,他们通常不能同时检索到适当的代词形式。
