对过去事件的自传式记忆和对未来情景的想象既包括情节内容，也包括语义内容。将描述自传体事件时产生的“内部”(情节)和“外部”(语义)细节的数量关联起来，可以阐明支持这些结构的过程之间的关系。然而，之前进行这种关联的研究局限于汇总个人产生的所有事件的数据，潜在地掩盖了事件本身的潜在关系。在目前的论文中，我们使用多层次方法重新分析了8项已发表研究的数据集，使我们能够探索事件内部和外部细节之间的关系。我们还检查了这种关系是否会随着健康老龄化而改变。我们的重新分析表明，在描述自传式记忆和未来想象力时，内部和外部细节之间存在很大程度上的负面关系。这种负面关系在老年人中更强烈和更一致，在语义内容的直接和间接测量中都很明显。此外，这种关系似乎是特定于情节任务，因为在非情节图片描述任务中没有观察到关系。这种负面关联表明，人们并不是不分青红皂白地产生语义信息，而是以一种补偿的方式这样做，以美化偶尔发生的贫困事件。我们的重新分析进一步支持了在记忆和想象自传体事件时支持情节和语义信息生成的可分离过程。
Autobiographical memories of past events and imaginations of future scenarios comprise both episodic and semantic content. Correlating the amount of “internal” (episodic) and “external” (semantic) details generated when describing autobiographical events can illuminate the relationship between the processes supporting these constructs. Yet previous studies performing such correlations were limited by aggregating data across all events generated by an individual, potentially obscuring the underlying relationship within the events themselves. In the current paper we reanalyzed datasets from eight published studies using a multilevel approach, allowing us to explore the relationship between internal and external details within events. We also examined whether this relationship changes with healthy aging. Our reanalyses demonstrated a largely negative relationship between the internal and external details produced when describing autobiographical memories and future imaginations. This negative relationship was stronger and more consistent for older adults, and was evident both in direct and indirect measures of semantic content. Moreover, this relationship appears to be specific to episodic tasks, as no relationship was observed for a non-episodic picture description task. This negative association suggests that people do not generate semantic information indiscriminately, but do so in a compensatory manner, to embellish episodically impoverished events. Our reanalysis further lends support for dissociable processes underpinning episodic and semantic information generation when remembering and imagining autobiographical events.
