People often engage in the selective remembering of valuable or important information, whether strategic and/or automatic. We examined potential age-related differences in the automatic processing of value during encoding on later remembering by presenting participants with words paired with point values (range: 1-10 twice or 1-20) to remember for a later test. On the first three lists, participants were told that they would receive the points associated with each word if they recalled it on the test (their goal was to maximize their score). On the last three lists, we told participants that all words were worth the same number of points if recalled on the tests, thus making the point value paired with each word meaningless. Results revealed that selective memory may be impaired in older adults using procedures with larger value ranges. Additionally, we demonstrated that the automatic effects of value may have a greater effect on younger adults relative to older adults, but there may be instances where older adults also exhibit these automatic effects. Finally, strategic and automatic processes may not be related within each learner, suggesting that these processes may rely on different cognitive mechanisms. This indicates that these processes could be underpinned by distinct cognitive mechanisms: strategic processes might engage higher-level cognitive operations like imagery, while automatic processes appear to be more perceptually driven.
人们经常会选择性地记住有价值或重要的信息,无论这种记忆是策略性的还是自动的。我们通过向参与者呈现与分值(范围:1 - 10分,呈现两次,或1 - 20分)配对的单词,让他们记住以便后续测试,来研究编码过程中价值的自动加工方面潜在的年龄相关差异。在前三个列表中,参与者被告知如果他们在测试中回忆起每个单词,就会得到与之相关的分数(他们的目标是使分数最大化)。在最后三个列表中,我们告诉参与者如果在测试中回忆起所有单词,它们的分值都是相同的,这样与每个单词配对的分值就变得毫无意义。结果显示,使用更大分值范围程序时,老年人的选择性记忆可能会受损。此外,我们证明,相对于老年人,价值的自动效应可能对年轻人有更大影响,但在某些情况下老年人也可能表现出这些自动效应。最后,策略性和自动加工过程在每个学习者内部可能并无关联,这表明这些过程可能依赖于不同的认知机制。这表明这些过程可能由不同的认知机制支撑:策略性过程可能涉及更高层次的认知操作,如图像化,而自动加工过程似乎更多地由感知驱动。
