年轻人和老年人在电脑屏幕上阅读一系列说明性文章，通过逐个领域的自我调整来快速回忆。使用扇区阅读时间（RT）的回归分析来估计个体在词级（即音节长度和平均词频）、文本级（即命题数量、引入的新概念数量和总Yngve深度）和篇章级（即序列位置）特征上分配的时间。在阅读时间分配模式上发现了年龄差异，这导致了高水平的回忆。具体来说，获得高回忆的年轻人对单词频率和新概念的引入反应更灵敏。相比之下，老年人的高回忆与更大程度的在线语境促进（即更陡峭的序列位置效应）有关。这些数据表明，在如何分配编码资源以优化后续记忆性能方面存在年龄差异。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Younger and older adults read a series of expository passages for immediate recall by self-pacing the presentation sector-by-sector on a computer screen. Regression analysis of sector reading times (RT) was used to estimate the time allocated by individuals to word-level (ie, syllable length and mean word frequency), text-level (ie, number of propositions, number of new concepts introduced, and total Yngve depth), and discourse-level (ie, serial position) features. Age differences were found in the pattern of reading time allocation that engendered high levels of recall. Specifically, younger adults who achieved high recall were more responsive to word frequency and the introduction of new concepts. By contrast, high recall among the old was related to a greater degree of on-line contextual facilitation (ie, a steeper serial position effect). These data suggest that there is an age difference in how the allocation of resources at encoding optimizes subsequent memory performance.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
