Prospective memory (PM)-the process of establishing intentions for future action and remembering to fulfill these intentions at the appropriate time-is necessary for many instrumental activities of daily living and for maintaining functional independence with increased age. Offloading PM demands onto the environment, such as setting a reminder alarm to take medication, offers an easy and effective way to mitigate age-related PM declines. However, a lack of basic knowledge about the cognitive and metacognitive processes that drive offloading decisions presents barriers to successful implementation. The present study addresses these issues by examining age differences in PM for offloaded (i.e., with reminders) and nonoffloaded (i.e., without reminders) intentions under low and high memory demands. With highly specific intentions that can be retrieved via bottom-up processes (Experiment 1), there were no age differences in PM without reminders, and younger and older adults equally benefitted from reminders under high memory load. With nonspecific intentions that require top-down attention for retrieval (Experiment 2), older adults had worse PM under high load without reminders. Critically, this age difference was eliminated with the use of reminders, likely due to increased reminder checking for older adults under high load. These findings suggest that offloading can circumvent cognitive capacity limitations and minimize computational effort to improve intention fulfillment in older adults. The theoretical and applied ramifications of these findings are discussed. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
前瞻性记忆(PM)——为未来行动制定意图并在适当时间记住履行这些意图的过程——对于许多日常生活中的工具性活动以及随着年龄增长维持功能独立性而言是必要的。将前瞻性记忆需求转移到环境中,比如设置服药提醒闹钟,提供了一种减轻与年龄相关的前瞻性记忆衰退的简单有效方法。然而,缺乏关于驱动转移决策的认知和元认知过程的基本知识,给成功实施带来了障碍。本研究通过考察在低记忆需求和高记忆需求下,有提示(即有提醒)和无提示(即无提醒)意图的前瞻性记忆中的年龄差异来解决这些问题。对于可以通过自下而上的过程检索的高度特定意图(实验1),无提醒时前瞻性记忆不存在年龄差异,并且在高记忆负荷下年轻人和老年人从提醒中同样受益。对于需要自上而下的注意力来检索的非特定意图(实验2),老年人在高负荷且无提醒时前瞻性记忆较差。关键的是,使用提醒消除了这种年龄差异,这可能是由于高负荷下老年人对提醒检查的增加。这些发现表明,转移可以规避认知能力限制,并将计算努力最小化,以提高老年人意图的履行。讨论了这些发现的理论和应用影响。(PsycInfo数据库记录(c)2025美国心理学会,保留所有权利)
