在情节记忆中，老年人比年轻人更容易混淆真实和想象的事件。这一缺陷可归因于可用于回忆的具体特征的减少(即检索成功)或在回忆尝试期间操作的搜索和决策过程中的缺陷(即检索监测)。本实验使用两阶段事件生成任务来操纵提取成功，并测试提取监控中与年龄相关的缺陷。在第一阶段，参与者根据他们的过去生成真实的自传性事件，并根据提示词想象看似合理的未来事件。我们使用精化说明来实验性地操作与这些生成的事件相关联的特性的数量。在24小时后进行的第二阶段，我们进行了回忆测试，要求参与者区分这些先前在记忆中产生的过去和未来的事件。正如预测的那样，精加工操作增加了两个年龄组中与产生的事件相关的特征回忆的数量(包括实验1中的认知操作和实验2中的知觉细节)。然而，老年人比年轻人更有可能在记忆中混淆过去和未来的事件，关键的是，精加工并没有减少这些与年龄相关的混淆。这些发现表明，衰老削弱了准确监控自传体事件特征提取的能力，而不是年龄相关的信息提取本身的损害。
Older adults are more likely than younger adults to confuse real and imagined events in episodic memory. This deficit may be attributed to a reduction in the specific features available for recollection (i.e. retrieval success) or to a deficit in the search and decision processes operating during recollection attempts (i.e. retrieval monitoring). The present experiments used a two-phase event-generation task to manipulate retrieval success and test for age-related deficits in retrieval monitoring. In the first phase, participants generated real autobiographical events from their past and imagined plausible future events in response to cue words. We used elaboration instructions to experimentally manipulate the amount of features associated with these generated events. In the second phase administered 24 hours later, we gave recollection tests that required participants to discriminate between these previously generated past and future events in memory. As predicted, the elaboration manipulation increased the amount of features that could be recollected in association with the generated events in both age groups (including cognitive operations in Experiment 1 and perceptual details in Experiment 2). However, older adults were more likely than younger adults to confuse past and future events in memory, and critically, elaboration did not minimize these age-related confusions. These findings imply that aging impairs the ability to accurately monitor retrieval for features that are characteristic of autobiographical events, above and beyond age-related impairments in the retrieval of the recollected information itself.
