作者提出了一个虚幻的回忆解释为什么认知老化与情节记忆缺陷有关。在听过女性或男性发言者的陈述后，老年人容易对过去的事件产生错误的回忆。作者的虚幻回忆账户在一个新的虚幻回忆信号检测模型中实例化，该模型比标准信号检测模型更适合老年人的数据。他们观察到，来源记忆中与年龄相关的差异（通过来源d'得分来衡量）在解释了虚幻回忆的发生后几乎消失了。这些数据表明，与年龄相关的源记忆障碍并不是因为老年人记住的诊断源信息较少，而必须猜测更多。相反，老年人似乎比年轻人更容易记错过去的事件。
The authors propose an illusory recollection account of why cognitive aging is associated with episodic memory deficits. After listening to statements presented by either a female or a male speaker, older adults were prone to misrecollecting past events. The authors' illusory recollection account is instantiated in a new illusory recollection signal detection model that provides a better fit of older adults' data than does the standard signal detection model. They observed that age-related differences in source memory (as measured by source d' scores) virtually disappear after accounting for the occurrence of illusory recollections. These data suggest that age-related source memory impairments are not due to older adults' remembering less diagnostic Source information and having to guess more. Instead, older adults appear to misremember past events more often than younger adults.
