This study investigates the processing of quantifiers in a patient (AM) with semantic dementia. Quantifiers are verbal expressions such as "many" or "a few", which refer semantically to quantity concepts although lexically they are like non-quantity words. Patient AM presented with preserved understanding of quantifier words and impaired understanding of non-quantifier words of the same frequency. In parallel to this, he showed preserved numerical knowledge and impaired comprehension of the meaning of words, objects, and of linguistic concepts. These results suggest that the neural organization of quantifiers is within the numerical domain as they pattern with numerical concepts rather than linguistic concepts. These data reinforce the evidence that numerical knowledge is functionally distinct from non-numerical knowledge in the semantic system and indicate that the semantic referent rather than the stimulus format is more relevant for semantic processing.
本研究调查了一名患有语义性痴呆的患者（AM）对数量词的处理情况。数量词是诸如“许多”或“几个”之类的语言表达，尽管在词汇上它们类似于非数量词，但在语义上它们指的是数量概念。患者AM对数量词的理解保持完好，而对相同频率的非数量词的理解受损。与此同时，他的数字知识保持完好，但对单词、物体和语言概念的意义理解受损。这些结果表明，数量词的神经组织属于数字领域，因为它们与数字概念而非语言概念具有相同的模式。这些数据强化了这样的证据，即数字知识在语义系统中在功能上与非数字知识不同，并表明语义指称而非刺激形式对于语义处理更为相关。
