先前的研究表明，老年人对语言的即时记忆较差，但原因尚不清楚。老年人可能会从工作记忆中回忆起更少的块，或者可能很难将单词结合在一起形成多单元块。我们通过呈现4种类型的口语句子用于立即自由回忆来检验这两个假设，每次试验的组块的数量和长度不同：4个简短的句子; 8个这样的句子; 4个复合句，每个复合句包含两个有意义的短句;和4个随机单词列表，每个都在一个类似连词的语调下。老年人回忆起的话（访问）少的条款比年轻的成年人，但没有老化赤字的程度完成的条款，访问。工作记忆容量的年龄相关性下降似乎可以解释口语记忆的缺陷。
Previous studies show that older adults have poorer immediate recall for language but the reason is unknown. Older adults may recall fewer chunks from working memory, or may have difficulty binding words together to form multi-unit chunks. We examined these two hypotheses by presenting 4 types of spoken sentences for immediate free recall, differing in the number and length of chunks per trial: 4 short, simple sentences; 8 such sentences; 4 compound sentences, each incorporating two meaningful, short sentences; and 4 random word lists, each under a sentence-like intonation. Older adults recalled words from (accessed) fewer clauses than young adults, but there was no aging deficit in the degree of completion of clauses that were accessed. An age-related decline in working memory capacity measured in chunks appears to account for deficits in memory for spoken language.
