Children with specific language impairment (CwSLI) are consistently reported to have short-term memory (STM) and working memory (WM) difficulties.
To compare STM and WM abilities in CwSLI with children with pragmatic language impairment (CwPLI).
METHODS & PROCEDURES: Primary school-aged CwSLI (n= 12) and CwPLI (n= 23) were assessed on measures of STM and WM.
OUTCOMES & RESULTS: CwPLI had significantly higher scores than CwSLI on STM tasks, and this difference could not be accounted for by differences in receptive language ability. There were no between-group differences for WM tasks. The majority of CwSLI and a significant proportion of CwPLI scored in the impaired range on each of the memory measures. In contrast, some CwPLI scored within the normal range.
CONCLUSIONS & IMPLICATIONS: CwPLI present with a different profile of STM but not WM ability to CwSLI. Clinical implications are discussed.
患有特定语言障碍（CwSLI）的儿童普遍存在短期记忆（STM）和工作记忆（WM）困难。
比较 CwSLI 与具有语用语言障碍（CwPLI）的儿童的 STM 和 WM 能力。
对小学年龄的 CwSLI（n=12）和 CwPLI（n=23）进行 STM 和 WM 测量。
CwPLI 在 STM 任务上的得分明显高于 CwSLI，而这种差异不能用接受性语言能力的差异来解释。在 WM 任务上，两组之间没有差异。大多数 CwSLI 和相当一部分 CwPLI 在每项记忆测试中得分都在受损范围内。相比之下，一些 CwPLI 的得分在正常范围内。
CwPLI 与 CwSLI 相比，在 STM 但不在 WM 能力方面表现出不同的模式。讨论了临床意义。
