The present study tested the hypothesis that the age deficits in memory span commonly found in elderly adults are attributable, at least in part, to elaborative rehearsal processes. The test required an analysis of age differences between young and elderly adult subjects in word span for list types varying in word frequency. Significant age deficits were found for all list types, with the magnitude of the deficit increasing as the frequency of intrastring items increased. The pattern of this interaction indicated the involvement of a decreased proficiency in elaborative rehearsal with increasing age as a contributor to the age deficit in word span.
本研究检验了这样一个假设，即老年人中常见的记忆广度年龄缺陷至少部分归因于精细复述过程。该测试要求分析年轻和老年受试者在单词频率不同的列表类型的单词广度上的年龄差异。所有列表类型都发现了显著的年龄缺陷，随着字符串内项目频率的增加，缺陷的程度也在增加。这种相互作用的模式表明，随着年龄的增长，精细复述能力下降是导致单词广度年龄缺陷的一个因素。
