This study examined the ability of 17 patients with Alzheimer's disease and 17 normal-old subjects to recall short sentences that were normal, or had a disruption in either their semantic structure, their syntactic structure, or both their semantic and syntactic structure. Results showed that sentence recall performance was affected similarly in the demented and normal-old subjects by both the syntactic and semantic structure of the sentences. The presence of either type of language structure appeared to allow both normal and demented subjects to organize strings of words into multiword chunks for more efficient memory encoding.
本研究考察了17名阿尔茨海默病患者和17名正常老年人回忆正常句子、语义结构被打乱的句子、句法结构被打乱的句子或语义和句法结构均被打乱的句子的能力。结果显示，痴呆患者和正常老年人的句子回忆表现受句子的句法和语义结构影响的方式相似。这两种语言结构的存在似乎都能使正常人和痴呆患者将单词串组织成多词块，从而更有效地进行记忆编码。
