We rely upon prospective memory proper (ProMP) to bring back to awareness previously formed plans and intentions at the right place and time, and to enable us to act upon those plans and intentions. To examine age-related changes in ProMP, younger and older participants made decisions about simple stimuli (ongoing task) and at the same time were required to respond to a ProM cue, either a picture (visually cued ProM test) or a sound (auditorily cued ProM test), embedded in a simultaneously presented series of similar stimuli (either pictures or sounds). The cue display size or loudness increased across trials until a response was made. The cue size and cue loudness at the time of response indexed ProMP. The main results showed that both visual and auditory ProMP declined with age, and that such declines were mediated by age declines in sensory functions (visual acuity and hearing level), processing resources, working memory, intelligence, and ongoing task resource allocation.
我们依靠前瞻记忆本身（ProMP）在合适的地点和时间将先前形成的计划和意图带回意识中，并使我们能够根据这些计划和意图采取行动。为了研究ProMP中与年龄相关的变化，年轻和年长的参与者对简单刺激（正在进行的任务）做出决策，同时被要求对嵌入在同时呈现的一系列相似刺激（图片或声音）中的ProM提示做出反应，该提示可以是图片（视觉提示的ProM测试）或声音（听觉提示的ProM测试）。在试验过程中，提示显示的大小或音量会增加，直到做出反应。做出反应时的提示大小和提示音量代表了ProMP。主要结果表明，视觉和听觉ProMP都会随着年龄的增长而下降，并且这种下降是由感觉功能（视力和听力水平）、处理资源、工作记忆、智力以及正在进行的任务资源分配方面的年龄下降所介导的。
