Six agrammatic aphasics repeated simple active and passive voice sentences, varying in degree of semantic constraint: plausible, reversible, and implausible. Frequency of correct response was not sensitive to this semantic manipulation, but error pattern was. In general, errors to plausible targets consisted of relatively inconsequential transformation of the open or closed class vocabulary, while errors to implausible targets implicated a change of syntactic voice. In making these errors, the patients displayed evidence of productive control of the passive morphology and a degree of sensitivity to the syntactic and thematic consequences consequences of passive voice. The repetition errors did not transform the surface order of the major lexical items. The results are interpreted as evidence for a sentence memory trace that preserves, minimally, the major grammatical roles of the target sentence and that serves as input to a reconstructive process that is biased toward the production of semantically plausible sentences.
六名语法缺失性失语症患者重复简单的主动语态和被动语态句子，这些句子在语义限制程度上有所不同：合理的、可逆的和不合理的。正确反应的频率对这种语义操作不敏感，但错误模式敏感。一般来说，对合理目标的错误由开放或封闭类词汇的相对无关紧要的转换组成，而对不合理目标的错误则涉及句法语态的改变。在犯这些错误时，患者表现出对被动形态的有效控制以及对被动语态的句法和主题结果的一定敏感性。重复错误并没有改变主要词汇项目的表面顺序。这些结果被解释为存在句子记忆痕迹的证据，该痕迹至少保留了目标句子的主要语法角色，并作为偏向于生成语义合理句子的重构过程的输入。
