Twenty asphasics repeated grammatical and ungrammatical sentences. Ungrammatical sentences were characterized by violations of syntactic and/or semantic structure. Aphasics repeated accurately more grammatical than ungrammatical sentences. Ungrammatical sentences with violations of syntactic structure were repeated less accurately than those with preserved syntax. Aphasics' repetition errors were classified as: incorrect repetition, inapropriate correction, morphological error, lexical deletion and substitution responses. Repetition errors appeared to result from performance deficits, such as reduced retention span and physiological limitations of the speech musculature. Results suggest that asphasics are to some extent guided by a greater residual linguistic knowledge or competence than might be inferred from their spontaneous production.
20 名失语症患者重复了符合语法和不符合语法的句子。不符合语法的句子以违反句法和/或语义结构为特征。失语症患者准确重复的符合语法的句子比不符合语法的句子更多。违反句法结构的不符合语法的句子比句法结构保留的句子重复得更不准确。失语症患者的重复错误被分类为：重复错误、不适当的纠正、形态错误、词汇删除和替代反应。重复错误似乎是由表现缺陷导致的，例如记忆跨度缩短和言语肌肉组织的生理限制。结果表明，失语症患者在某种程度上受到比从他们的自发言语中推断出的更多的残留语言知识或能力的引导。
