序列学习的结构和年龄的影响进行了调查，测试24名年轻人和24名老年人参加了10届交替序列反应时间任务，其中模式试验交替随机试验。个体遇到滞后2或滞后3结构，学习通过模式和随机试验之间的差异（反应时间和准确性）来衡量。两个年龄段的人都学会了滞后2结构，但年轻人比年长的参与者学到的更多。只有年轻人学会了滞后3结构，他们学习滞后2结构的速度更慢，程度也更低。这些年龄赤字高阶序列学习后，延长的做法是一致的一致性理论和理论假设，年龄相关的缺陷，在神经调节导致不太独特的代表。
The influence of structure and age on sequence learning was investigated by testing 24 young and 24 older participants for 10 sessions in an alternating serial response time task in which pattern trials alternated with random trials. Individuals encountered lag-2 or lag-3 structure, and learning was measured by the difference (in response time and accuracy) between pattern and random trials. Both ages learned lag-2 structure, but the young learned more than the older participants. Only the young people learned lag-3 structure, and they did so more slowly and to a lesser degree than they learned lag-2 structure. These age deficits in higher order sequence learning after extended practice are consistent with simultaneity theory and with theories positing that age-related deficits in neuromodulation lead to less distinctive representations.
