本研究探讨了特殊语言障碍儿童的言语工作记忆容量。本研究采用Gaulin和坎贝尔（1994）提出的竞争性语言加工任务（CLPT）。共40名学龄儿童参加了这项调查，其中包括20名SLI和20名正常语言（NL）年龄匹配的对照。结果表明，SLI和NL组在真/假理解项目方面表现相似，但SLI儿童的单词回忆比NL对照组显着较差，即使在非语言认知得分差异进行统计控制。观察到的SLI和NL组的单词回忆错误的不同模式，以及CLPT单词回忆和非语言认知和语言措施的性能之间的关联的不同模式。研究结果的解释框架内的语言处理能力有限的模型。
This study investigated verbal working memory capacity in children with specific language impairment (SLI). The task employed in this study was the Competing Language Processing Task (CLPT) developed by Gaulin and Campbell (1994). A total of 40 school-age children participated in this investigation, including 20 with SLI and 20 normal language (NL) age-matched controls. Results indicated that the SLI and NL groups performed similarly in terms of true/false comprehension items, but that the children with SLI evidenced significantly poorer word recall than the NL controls, even when differences in nonverbal cognitive scores were statistically controlled. Distinct patterns of word-recall errors were observed for the SLI and NL groups, as well as different patterns of associations between CLPT word recall and performance on nonverbal cognitive and language measures. The findings are interpreted within the framework of a limited-capacity model of language processing.
