This study is concerned with characteristics of short-term memory (STM) in children with specific language impairment (SLI). The linguistic requirements of the test procedure, the characteristics of the test materials, and the development of linguistic representations were considered. Two experimental tasks were used: a verbal-repetition and a picture-pointing procedure. The tasks used auditory presentation and were designed to explore different underlying processes during immediate recall. The linguistic characteristics of the test materials were designed to explore the influence of semantic, lexical, and phonological factors on STM. Six SLI children (aged 6:1 to 9:6) (years:months) were individually matched on comprehension and expression of language to 17 younger children (age 3:4 to 6:5). Both groups were differentially influenced by the materials as a function of the test procedure. In general, both group and individual analyses found no significant difference between the performance of the SLI children and language-age (LA) controls. The implications of the results in relation to previous findings from investigations of STM and the underlying cause of SLI in children are discussed.
本研究关注特定语言障碍（SLI）儿童的短期记忆（STM）特征。考虑了测试程序的语言要求、测试材料的特征以及语言表征的发展。使用了两项实验任务：言语重复和图片指认程序。这些任务采用听觉呈现方式，旨在探索即时回忆过程中不同的潜在过程。测试材料的语言特征旨在探究语义、词汇和语音因素对STM的影响。6名SLI儿童（年龄在6岁1个月至9岁6个月之间）在语言理解和表达方面与17名年龄较小的儿童（年龄在3岁4个月至6岁5个月之间）进行了个体匹配。两组在测试程序中均受到材料的不同影响。总体而言，无论是组间分析还是个体分析，均未发现SLI儿童与语言年龄（LA）对照组在表现上存在显著差异。讨论了这些结果与先前关于STM研究结果以及儿童SLI潜在原因的关系。
