The relationship between sentence comprehension and grammaticality judgment was examined for both neurologically intact and agrammatic aphasic subjects. Aphasic subjects were able to make grammaticality judgments and comprehension judgments, but were less accurate than healthy control subjects. However, the tasks appeared dissociated for the aphasic subjects: Both the effects of semantic cues and the hierarchy of difficulty of sentence types differed across the two tasks. Further, the findings suggest that not all aspects of morpho-syntactic processing may be equally disrupted in aphasia. The results argue against both a central deficit view of agrammatic aphasia, and a view suggesting that syntactic processing is intact whereas semantic or thematic mapping is not. Instead, the results indicate that the respective performance domains of comprehension and grammaticality judgment may draw on different processes and/or operate on different aspects of the language input.
研究了神经功能正常和语法缺失性失语症患者在句子理解和语法判断之间的关系。失语症患者能够进行语法判断和理解判断，但准确性低于健康对照受试者。然而，对于失语症患者来说，这两项任务似乎是分离的：语义线索的影响和句子类型的难度等级在这两项任务中都有所不同。此外，研究结果表明，形态句法处理的并非所有方面在失语症中都会受到同等程度的干扰。这些结果反对语法缺失性失语症的中枢缺陷观点，也反对认为句法处理完好而语义或主题映射受损的观点。相反，结果表明，理解和语法判断各自的表现领域可能利用不同的过程和/或作用于语言输入的不同方面。
