The error patterns of normal and aphasic adults on a sentence comprehension test were studied. For position of error, both normals and the three aphasic groups performed consistently with the expected error distribution. Neither sentence half was experienced as more difficult to process. All groups, both aphasic and normal, demonstrated error patterns for grammatical class and for surface structure linguistic constituent which were consistent with the expected error distributions. Exceptions were noted for the normals on the verb class and for the Wernicke's aphasics on the NP and VP linguistic constituents. Rank orderings of error proportions were similar across groups for both grammatical form class and linguistic constituent. The general findings lend support to the notion that, for auditory comprehension of sentences, aphasic patients differ quantitatively from normal adult speakers, but behave qualitatively similar to them.
研究了正常成年人与失语成年人在句子理解测试中的错误模式。对于错误位置，正常人和三个失语组的表现均与预期的错误分布一致。句子的前半部分和后半部分在处理难度上并无差异。所有组，包括失语组和正常组，在语法类别和表层结构语言成分方面的错误模式均与预期的错误分布一致。正常组在动词类别上以及韦尼克失语症患者在名词短语和动词短语语言成分上存在例外情况。对于语法形式类别和语言成分，各组之间的错误比例排序相似。总体研究结果支持了这样一种观点，即对于句子的听觉理解，失语患者与正常成年说话者在数量上存在差异，但在质量上表现相似。
