本文讨论了最近的说法，语法类失语症患者之间发现的差异可能反映了语义因素，如容易imagermination，而不是词汇/句法类。名词和动词等同于额定的意象，频率和长度被引出作为完成口语句子。五名失语症患者在图片命名中名词的产出显著优于动词，他们在完成任务中继续表现出显著的语法类效应。两名在口头阅读中具有显着可成像性效应的患者在句子完成中继续表现出可成像性效应，但其中只有一名患者在产生动词时表现出任何困难。对个体患者数据的检查表明，语法类别或意象，或两个变量都可能影响患者的表现，但它们的影响是相互独立的。(C)2002爱思唯尔科技有限公司版权所有。
This paper addresses the recent claim that grammatical class differences found among aphasic patients may reflect semantic factors such as ease of imageability rather than lexical/syntactic class. Nouns and verbs equated for rated imageability, frequency and length were elicited as completions for spoken sentences. Five aphasic patients with significantly better production of nouns than verbs in picture naming continued to show a significant grammatical class effect in the completion task. Two patients with significant imageability effects in oral reading continued to show imageability effects in sentence completion, but only one of these patients showed any difficulty producing verbs. Inspection of the individual patient data indicated that either grammatical class, or imageability, or both variables may affect patient performance, but that their effects are independent of one another.
