本实验探讨了阿尔茨海默病（Alzheimer’s disease， AD）受试者和年龄、学历匹配对照者对四种语义关系（上级范畴、部分、性质和功能）的认知。中度AD被试对功能关系的破坏最大，对部分和财产关系的破坏中等，对类别关系的破坏最小；轻度AD受试者表现出类似的模式，但仅在功能上有明显的缺陷。我们认为，功能上不成比例的缺陷反映了功能比其他语义关系更大的认知复杂性，这使得它们更容易受到中断处理或语义概念之间关联网络结构退化的影响。（黄金，1995,1,568-574 .）
This experiment explored knowledge of four types of semantic relations (superordinate category, part, property, and function) in Alzheimer's disease (AD) subjects and age- and education-matched controls. Moderate AD subjects showed the greatest disruption on functional relations, intermediate disruption on part and property relations, and the least disruption on category relations; mild AD subjects showed a similar pattern but significant deficits only on functions. We suggest that the disproportionate deficit on functions reflects a greater cognitive complexity of functions than other semantic relations that renders them more vulnerable either to disrupted processing or to structural degradation of the network of associations among semantic concepts.
