阿尔茨海默型痴呆症(DAT)患者和年龄和教育程度相匹配的老年志愿者进行了一系列工作记忆测试,以及两项句子理解测试。患者的跨度减少和受损的中央执行过程中的工作记忆,但表现出正常的影响,语音和发音变量的跨度。在句子理解任务中,DAT患者表现出句子中命题数量的效应,但不表现出句法复杂性的效应。DAT患者工作记忆中央执行过程的损害与句子中命题数量对句子理解任务的影响相关。结果表明,DAT患者的工作记忆障碍与他们将句子的含义映射到世界上事件的描述的能力有关。
Patients with dementia of the Alzheimer’s type (DAT) and age- and education-matched older volunteers were tested on a battery of working memory tests, as well as on two tests of sentence comprehension. Patients had reduced spans and impaired central executive processes in working memory but showed normal effects of phonological and articulatory variables on span. On the sentence comprehension tasks, DAT patients showed effects of the number of propositions in a sentence but not of syntactic complexity. Impairment in the central executive processes of working memory in DAT patients was correlated with the effect of the number of propositions in a sentence on the sentence comprehension tasks. The results suggest that patients with DAT have working memory impairments that are related to their ability to map the meanings of sentences onto depictions of events in the world.
