A number of recent articles have claimed that the language comprehension impairments of so-called agrammatic patients can be characterized as being due to problems with the automatic access of semantic and/or syntactic information from the lexicon. We describe three experiments, all using tasks which probe the immediate and automatic access of lexical information and compare the performance of agrammatic patients with that of an anomic and a fluent patient. We find no evidence in support of the automaticity hypothesis as an explanatory account of the language deficits of agrammatic aphasics. Further, we argue that current research does not lend itself to a single-explanation account of agrammatic comprehension problems, and that in-depth analyses of individual patients are more likely to be fruitful in terms of understanding the nature of comprehension deficits.
最近有一些文章声称，所谓语法缺失患者的语言理解障碍可以被描述为是由于从词汇库中自动获取语义和/或句法信息存在问题所致。我们描述了三个实验，所有实验都使用了探测词汇信息即时和自动获取的任务，并将语法缺失患者的表现与一名命名性失语患者和一名流畅性失语患者的表现进行了比较。我们没有发现证据支持将自动性假设作为对语法缺失失语症患者语言缺陷的一种解释。此外，我们认为目前的研究并不适合对语法缺失理解问题进行单一解释，而且就理解理解缺陷的本质而言，对个体患者进行深入分析更有可能取得成果。
