利用Hermer-Vazquez的重新定向范式，研究获得性语言障碍个体的空间认知可以帮助我们理解语言成分是如何参与空间表征的。Spelke和Katsnelson（1999）。我们研究了严重语法性失语症或全身性失语症患者和一组健康老年人的空间线索整合（地标性几何连词），失语症患者在重新定向任务中的表现与健康对照组相似，表现出整合地标性和几何线索的能力。这些结果扩展了先前对健康成年人的研究结果，表明在成熟的认知系统中，句法和词汇都不是空间线索表征所必需的。并提供进一步的证据，证明失语症中的语言缺陷可以独立于其他推理领域
Investigating spatial cognition in individuals with acquired language impairments can inform our understanding of how components of language are involved in spatial representation Using the reorientation paradigm of Hermer-Vazquez. Spelke, and Katsnelson (1999). we examined spatial cue integration (landmark geometry conjunctions) in individuals with severe agrammatic or global aphasia and in a group of healthy older adults Participants with aphasia performed similarly to healthy controls in the reorientation task, demonstrating the ability to integrate landmark and geometric cues, even during a concurrent verbal task designed to block access to any residual lexical resources These results extend previous findings with healthy adults by suggesting that neither syntax nor lexicon is essential for spatial cue representation in a mature cognitive system. and provide further evidence that language deficits in aphasia can be independent from other domains of reasoning
