Abstract This study examines French object clitic production in 20 typically developing L2 children (L1 English) compared to 19 monolingual children with SLI. We collected spontaneous and elicitation data twice at a one-year interval (T1, T2) in order to better evaluate the impact of age- and time-related factors on the L2-SLI comparison, as well as the impact of proficiency and working memory on object clitic production. The data revealed considerable group overlap at T1 in both tasks, but the L2 children produced significantly more object clitics than the SLI group at T2 in spontaneous language, thus suggesting that the L2-SLI overlap decreases when the L2 children have more language exposure. In elicitation, clitic production in both groups increased from T1 to T2 when all clitic types were included, but when only 3p accusative clitics were analyzed, the L2 children outperformed the SLI group. Age played an important role in elicitation in both groups, thus suggesting that mature performance systems, including unimpaired working memory, are required for object clitic production in this task. Language-related measures were linked to both tasks, thus suggesting that object clitic production is particularly sensitive to overall language proficiency, possibly because of issues with resource allocation.

法语 L2 儿童和 SLI 儿童中的客体 clitic 产生

摘要 本研究比较了 20 名典型的 L2 儿童（L1 英语）与 19 名单语 SLI 儿童的法语客体 clitic 产生。为了更好地评估年龄和时间相关因素对 L2-SLI 比较的影响，以及熟练程度和工作记忆的影响，我们每隔一年收集两次自发和诱导数据（T1、T2）关于客体的生产。数据显示两个任务在 T1 时有相当大的组重叠，但 L2 儿童在 T2 时在自发语言中比 SLI 组产生了明显更多的客体附着点，因此表明当 L2 儿童有更多的语言接触时，L2-SLI 重叠减少。在诱导方面，当包括所有阴蒂类型时，两组的阴蒂产量从 T1 增加到 T2，但是当仅分析 3p 指责 clitics 时，L2 儿童的表现优于 SLI 组。年龄在两组的诱导中都发挥了重要作用，因此表明在这项任务中，对象附着产生需要成熟的表现系统，包括未受损的工作记忆。与语言相关的测量与这两项任务都相关，因此表明客体的产生对整体语言能力特别敏感，可能是因为资源分配问题。
