我们考察了年轻人和老年人在没有使用组块的外部诱因的情况下在记忆中组织字母序列的能力。为了做到这一点，受试者接受了配对联想、连续回忆任务的测试。根据这些数据计算完全回忆序列的数量，以及全局和停止转移错误概率(TEP)。与年轻人相比，老年人回忆起的正确字母序列较少，但GLOBAL和STOP TEP数据表明，两个年龄段的人都将四个字母序列分成两组，每组两个字母。因此，本研究表明，初级组织结构不存在年龄差异，但老年人在连续回忆中表现出年龄缺陷。
We examined the ability of younger and older adults to organize letter sequences in memory when no external inducement of chunking was used. In order to do so, subjects were tested on a paired-associate, serial recall task. From these data the number of completely recalled sequences was computed, as well as global and stop transitional error probabilities (TEPs). Older adults recalled fewer correct letter sequences than did the young adults, but the global and stop TEP data indicated that both age groups were chunking the four-letter sequences into two sets of two letters. Thus, the present study indicates that there are no age differences in primary organization, but that older adults exhibit an age deficit in serial recall.
