3 个实验考察了年轻人和老年人的串行模式学习。与通常的重复模式不同，这些序列在重复模式的事件和随机确定的事件之间交替。结果表明，没有人能够描述这种规律性，但通过练习，所有 3 个年龄组（包括老年人）中的每个人在模式试验中都比随机试验变得更快、更准确，或两者兼而有之。尽管这表明所有年龄段的成年人都能够学习序列中的二阶统计依赖性，但在模式学习的幅度上却出现了与年龄相关的缺陷。所学到的知识也存在年龄差异，只有年轻人才表现出对序列中高阶统计依赖性的敏感性。此外，虽然年轻人在随后的概念驱动生产测试中揭示了他们模式学习的证据，但年轻人和老年人却没有。（PsycINFO 数据库记录 (c) 2016 APA，保留所有权利）
3 experiments examined serial pattern learning in younger and older adults. Unlike the usual repeating pattern, the sequences alternated between events from a repeating pattern and those determined randomly. The results indicated that no one was able to describe the regularity, but with practice every individual in all 3 age groups (including old old) became faster, more accurate, or both, on pattern trials than on random trials. Although this indicates that adults of all ages are able to learn second-order statistical dependencies in a sequence, age-related deficits were obtained in the magnitude of pattern learning. There were also age differences in what was learned, with only younger people revealing sensitivity to higher order statistical dependencies in the sequence. In addition, whereas younger people revealed evidence of their pattern learning in a subsequent conceptually driven production test, young-old and old-old people did not.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
