研究了16名青年和16名老年人记忆负荷对瞳孔认知反应的影响。在斯滕伯格记忆搜索任务中，研究人员测量了平均瞳孔扩张和反应时间，该任务涉及六个级别的记忆负荷。结果表明，老年参与者的反应时间随记忆负荷的增加比年轻参与者的反应时间增加得多。在实验的编码阶段，平均扩张随记忆负荷的增加而增加。这里没有观察到年龄差异。然而，在实验的搜索阶段，年轻人的平均瞳孔扩张比老年人要大得多。此外，老年参与者的平均扩张对记忆负荷不敏感，而年轻参与者的平均扩张随着记忆负荷的增加而增加。结果表明，瞳孔反应作为记忆负荷微妙波动的相关性随着年龄的增长而减弱。
The effect of memory load on the cognitive pupillary response among 16 young adults and 16 older adults was investigated. Mean pupil dilation and reaction time were measured during a Sternberg memory-search task, which involved six levels of memory load. A classic interaction pattern was obtained in which the reaction times of the elderly participants increased more as a function of memory load than the reaction times of the young participants. In the encoding phase of the experiment, mean dilation increased with memory load. No age differences were observed here. In the search phase of the experiment, however, mean pupil dilation was considerably greater in the young than in the elderly participants. Moreover, mean dilation of the older participants was not sensitive to memory load, whereas mean dilation increased as a function of memory load in the young participants. The results suggest that the usefulness of the pupillary response as a correlate of subtle fluctuations in memory load diminishes with old age.
