目的：对特定语言障碍 (SLI) 背后的认知过程的调查表明，言语短期记忆和工作记忆，特别是语音信息的存储和处理存在缺陷。本研究调查了一组 SLI 儿童的视觉空间材料的短期和工作记忆，以测试已经建立的言语记忆障碍是否延伸到视觉空间领域。方法：15 名 SLI 儿童和年龄和语言年龄相匹配的对照组儿童完成了视觉空间短期和工作记忆测试。结果：SLI 组在所有指标上与年龄匹配的对照儿童的表现相当，并且水平高于语言年龄。结论：该 SLI 组的视觉空间短期记忆和工作记忆能力处于适合年龄的水平。这与他们在言语短期记忆和工作记忆测试中的缺陷形成鲜明对比。
Purpose: Investigations of the cognitive processes underlying specific language impairment (SLI) have implicated deficits in verbal short-term and working memory and in particular the storage and processing of phonological information. This study investigated short-term and working memory for visuospatial material for a group of children with SLI, to test whether the verbal memory impairments already established extend to the visuospatial domain.Method: Fifteen children with SLI and control groups of children matched on chronological age and language age completed tests of visuospatial short-term and working memory.Results: The SLI group performed comparably with age-matched control children on all measures and at a higher level than the language-age control group on several measures.Conclusions: The visuospatial short-term and working memory abilities were at age-appropriate levels in this SLI group. This contrasts markedly with their impairments on tests of verbal short-term and working memory.
