众所周知，记忆力在健康的衰老过程中会下降。然而，记忆并不是一个整体，它来自不同类型的表征。从历史上看，我们对与年龄相关的记忆衰退的理解大多源于对孤立的研究项目的认识。相比之下，现实生活中的事件通常被记住为叙述，而这类信息通常在典型的识别记忆研究中被遗漏。在这里，我们设计了一个任务，税记忆歧视的事件细节，直接对比知觉和叙事记忆。老年人和年轻人观看了一集电视节目，后来完成了一个旧/新的识别测试，包括目标，小说箔，以及叙事和感知领域的类似诱惑。虽然我们没有观察到与年龄相关的差异，重复的目标和新的箔的基本认识，老年人表现出赤字正确拒绝感性，但不是叙事，诱惑。这些发现提供了对衰老过程中不同记忆域的脆弱性的深入了解，并可能有助于表征处于病理性认知衰退风险中的个体。
Memory is well known to decline over the course of healthy aging. However, memory is not a monolith and draws from different kinds of representations. Historically, much of our understanding of age-related memory decline stems from recognition of isolated studied items. In contrast, real-life events are often remembered as narratives, and this kind of information is generally missed in typical recognition memory studies. Here, we designed a task to tax mnemonic discrimination of event details, directly contrasting perceptual and narrative memory. Older and younger adults watched an episode of a television show and later completed an old/new recognition test featuring targets, novel foils, and similar lures in narrative and perceptual domains. While we observed no age-related differences on basic recognition of repeated targets and novel foils, older adults showed a deficit in correctly rejecting perceptual, but not narrative, lures. These findings provide insight into the vulnerability of different memory domains in aging and may be useful in characterizing individuals at risk for pathological cognitive decline.
