我们报告了一个纵向研究的病人，ES，与进行性退行性疾病造成的广泛性脑萎缩。在一系列任务中，ES在识别和命名人工制品方面比生物更困难。随着时间的推移，这种人工制品的缺陷出现了，因为她变得更加严重受损，在一项任务中，图片命名，从最初的生物缺陷到后来的人工制品缺陷有一个交叉。所有材料都经过仔细控制，以排除潜在的混淆因素，如概念熟悉度或获得年龄。没有证据表明，ES的缺陷的文物与更大的损失功能比视觉信息。结果的模式是一致的，最近提出的分布式连接模型。在这种情况下，由于语义记忆受到严重的、普遍的损害，可能会出现人工制品概念的缺陷。(C)1999爱思唯尔科技有限公司。保留所有权利。
We report a longitudinal study of a patient, ES, with a progressive degenerative disorder resulting from generalised cerebral atrophy. Across a range of tasks, ES showed a greater difficulty in recognising and naming artifacts than living things. This deficit for artifacts emerged over time, as she became more severely impaired, in one task, picture naming, there was a crossover from an initial deficit for living things to the later artifact deficit. All materials were carefully controlled to rule out potential confounding factors such as concept familiarity or age of acquisition. There was no evidence that ES's deficit for artifacts was associated with a greater loss of functional than visual information. The pattern of results are consistent with a recently proposed distributed connectionist model. in which a deficit for artifact concepts can emerge as the result of severe, general damage to semantic memory.
