本研究采用一种新的词汇启动任务--阈口阅读，对阿尔茨海默病（AD）患者存在语义加工障碍的假设进行了检验。健康老年人对照组显示出显着的效果，启动词对联想相关的（可靠地共同出现在词联想测试）和词对语义相关的（高频率的例子，属于同一个上位类别，但不是高频联营公司）。AD患者表现出的影响，启动的联想相关的词，但不相关的词对，只有共享的语义特征。这些结果与AD中语义处理受损的假设一致，并表明语义记忆中单词之间和概念之间的独立关系网络可能会因各种形式的脑损伤而受到不同程度的破坏。
The hypothesis that patients with Alzheimer's disease (AD) have a disturbance in semantic processing was tested using a new lexical-priming task, threshold oral reading. Healthy elderly controls showed significant effects of priming for word pairs that are associatively related (words that reliably co-occur in word association tests) and for word pairs that are semantically related (high-frequency exemplars that belong to the same superordinate category but are not high-frequency associates). AD patients showed effects of priming for associatively related words but not for word pairs that are related only by shared semantic features. These results are consistent with the hypothesis that semantic processing is impaired in AD and suggest that independent networks of relationships among words and among concepts in semantic memory may be differentially disrupted with various forms of brain damage.
