Purpose The purpose of this study was to examine the use of structural priming combined with a focused recasting procedure to elicit subject- and object-focused, center-embedded relative clauses from students with developmental language disorders (DLDs) and typically developing (TD) students. Method A total of 26 children (13 DLD, 13 TD), ranging in age from 6;10 to 10;11 (years;months), participated in this study. All children completed a priming and recasting task that targeted subject- and object-focused relatives. The stimuli were presented in two blocks, which each contained 40 trials for each sentence type. Results Children with DLD and their TD peers were significantly more accurate producing subject-focused than object-focused relatives. An analysis of rate of learning indicated that significantly more trials were required for subjects in the DLD group to demonstrate consistent performance on both subject- and object-focused relatives. Conclusions The study supports the feasibility of combining an implicit priming task with an explicit recasting task for teaching subject-focused relative clauses to children with DLD. However, it is likely that additional instruction and/or more trials will be necessary for children with DLD to attain consistent performance levels.

目的 本研究旨在考察结构启动与聚焦重铸相结合的方法对发育性语言障碍(DLD)儿童和典型发展(TD)儿童提取主语和宾语中心嵌入式关系从句的影响。
方法 共有 26 名儿童(13 名 DLD,13 名 TD)参加了本研究,年龄在 6;10 到 10;11 岁之间。所有儿童都完成了一个针对主语和宾语关系从句的启动和重铸任务。刺激分两个块呈现,每个块包含 40 个每个句子类型的试验。
结果 DLD 儿童和他们的 TD 同伴在生成主语焦点关系从句时明显比生成宾语焦点关系从句更准确。学习率分析表明,在 DLD 组中,受试者需要更多的试验才能在主语和宾语焦点关系从句上表现出一致的性能。
结论 该研究支持将内隐启动任务与外显重铸任务相结合,用于教授 DLD 儿童主语焦点关系从句的可行性。然而,对于 DLD 儿童来说,可能需要更多的指导和/或更多的试验才能达到一致的表现水平。
