Aphasic patients often have more difficulty retrieving verbs than nouns. We present data from eight aphasics demonstrating that they have a selective impairment for verb retrieval. We then explore the role of semantic complexity (i.e., the number of semantic features) in verb retrieval using a delayed repetition/story completion task. The results indicate that six of the patients are better at retrieving semantically complex verbs (e.g., run) than semantically simpler verbs (e.g., go). The results have implications for accounts of the noun/verb dissociation in aphasia, as well as for theories of verb representation.
失语症患者在检索动词时往往比检索名词更困难。我们展示了来自八位失语症患者的数据，表明他们在动词检索方面存在选择性损伤。然后，我们使用延迟重复/故事完成任务来探究语义复杂性（即语义特征的数量）在动词检索中的作用。结果表明，六位患者在检索语义复杂的动词（如“跑”）时比语义简单的动词（如“去”）表现更好。这些结果对失语症中名词/动词分离的解释以及动词表征理论都有启示。
