Abstract
We tested the ability of Alzheimer's patients and elderly controls to name living and non-living nouns, and manner and instrument verbs. Patients' error patterns and relative performance with different categories showed evidence of graceful degradation for both nouns and verbs, with particular domain-specific impairments for living nouns and instrument verbs. Our results support feature-based, semantic representations for nouns and verbs and support the role of inter-correlated features in noun impairment, and the role of noun knowledge in instrument verb impairment.
摘要
我们测试了阿尔茨海默病患者和老年对照组命名有生命和无生命名词、方式动词和工具动词的能力。患者在不同类别上的错误模式和相对表现显示，名词和动词都存在渐进性退化的迹象，对有生命名词和工具动词有特定领域的损伤。我们的结果支持基于特征的名词和动词语义表征，支持相互关联的特征在名词损伤中的作用，以及名词知识在工具动词损伤中的作用。
