Patients with 'refractory semantic access deficits' demonstrate several unique features that make them important sources of insight into the organization of semantic representations. Here we attempt to replicate several novel findings from single-case studies reported in the literature. Patient UM-103 displays the cardinal features of a 'refractory semantic access deficit' and showed many of the same effects of semantic relatedness reported in the literature. However, when probing concrete and abstract words, this patient revealed very different patterns of performance compared to two previously reported patients. We discuss the implications of our data for models of semantic organization of abstract and concrete words.
患有“难治性语义通达缺陷”的患者表现出几个独特特征,这些特征使他们成为洞察语义表征组织的重要来源。在此,我们试图重复文献中报道的单病例研究的几个新发现。患者UM - 103表现出“难治性语义通达缺陷”的主要特征,并呈现出文献中报道的许多相同的语义相关性效应。然而,在探测具体词和抽象词时,该患者与之前报道的两名患者相比,表现出非常不同的模式。我们讨论了我们的数据对抽象词和具体词语义组织模型的意义。
