There is mixed evidence on the impact of delay task difficulty on prospective memory (PM) performance and little research has examined this among older adults. The present study examined younger (N = 60) and older (N = 57) adults' prospective memory (PM) performance after completing an easy or difficult Raven's matrices task. To assess whether delay difficulty impacted how often participants thought about their PM intention, participants were asked to report on what they thought about during the delay task itself and retrospectively after all tasks were completed. Younger adults outperformed older adults on the PM task; however, delay task difficulty had no impact PM for either age group. Reports of thinking about the intention during the delay task differed by age group depending whether they were online or retrospective, however, overall greater reports of thinking about the intention was positively associated with PM performance.
关于延迟任务难度对前瞻性记忆（PM）表现的影响，证据不一，而且很少有研究在老年人中对此进行研究。本研究考察了年轻人（N=60）和老年人（N=57）在完成简单或困难的瑞文标准推理测验任务后的前瞻性记忆（PM）表现。为了评估延迟难度是否会影响参与者思考 PM 意图的频率，要求参与者报告他们在延迟任务期间以及在所有任务完成后回想起来的内容。年轻组在 PM 任务上的表现优于老年组；然而，对于两个年龄组，延迟任务难度都没有对 PM 产生影响。根据是在线还是回溯，报告在延迟任务期间思考意图的情况因年龄组而异，但是，总体上，更多地报告思考意图与 PM 表现呈正相关。
