程序性记忆缺陷假说认为，程序性记忆的脑结构异常是特殊语言障碍儿童语言缺陷的主要原因。这些异常被假定为导致程序性记忆的核心缺陷，这反过来又解释了这种障碍中的语法问题。这些异常也可能导致其他非程序性功能的问题，例如工作记忆，这些功能至少部分依赖于受影响的大脑结构。相比之下，陈述性记忆预计将在很大程度上保持完整，并应发挥重要的语法补偿作用。通过检查51名SLI儿童和51名匹配的典型发育（TD）儿童（平均年龄10岁）的工作，陈述和程序记忆的措施，这些索赔进行了测试。工作记忆与儿童工作记忆成套测验，陈述性记忆与儿童记忆量表，程序性记忆与视觉空间序列反应时间任务进行了评估。与TD儿童相比，SLI儿童的程序记忆受损，即使在保持工作记忆不变的情况下。相比之下，他们在视觉信息的陈述性记忆中幸免于难，在控制工作记忆和语言后，他们在言语领域的陈述性记忆中幸免于难。视觉空间短期记忆是完整的，而文字工作记忆受损，即使在语言缺陷保持不变。相关分析表明，无论是视觉空间还是言语工作记忆都与SLI或TD儿童的词汇或语法能力无关。在两组儿童中，陈述性记忆与词汇能力相关。最后，语法能力与TD儿童的程序性记忆有关，但与SLI儿童的陈述性记忆有关。这些发现重复和扩展了以前的研究工作，陈述性和程序性记忆的SLI。总的来说，我们认为证据在很大程度上支持PDH的预测。
According to the Procedural Deficit Hypothesis (PDH), abnormalities of brain structures underlying procedural memory largely explain the language deficits in children with specific language impairment (SLI). These abnormalities are posited to result in core deficits of procedural memory, which in turn explain the grammar problems in the disorder. The abnormalities are also likely to lead to problems with other, non-procedural functions, such as working memory, that rely at least partly on the affected brain structures. In contrast, declarative memory is expected to remain largely intact, and should play an important compensatory role for grammar. These claims were tested by examining measures of working, declarative and procedural memory in 51 children with SLI and 51 matched typically-developing (TD) children (mean age 10). Working memory was assessed with the Working Memory Test Battery for Children, declarative memory with the Children’s Memory Scale, and procedural memory with a visuo-spatial Serial Reaction Time task. As compared to the TD children, the children with SLI were impaired at procedural memory, even when holding working memory constant. In contrast, they were spared at declarative memory for visual information, and at declarative memory in the verbal domain after controlling for working memory and language. Visuo-spatial short-term memory was intact, whereas verbal working memory was impaired, even when language deficits were held constant. Correlation analyses showed neither visuo-spatial nor verbal working memory was associated with either lexical or grammatical abilities in either the SLI or TD children. Declarative memory correlated with lexical abilities in both groups of children. Finally, grammatical abilities were associated with procedural memory in the TD children, but with declarative memory in the children with SLI. These findings replicate and extend previous studies of working, declarative and procedural memory in SLI. Overall, we suggest that the evidence largely supports the predictions of the PDH.
