Emotion has been suggested to slow forgetting via a mechanism that enhances memory consolidation. Here, we investigate whether this time dependent process influences the subjective experience of recollection as well as the ability to retrieve specific contextual details of the study event. To do so we examined recognition for emotional and neutral pictures at two retention intervals and collected remember/know reports and reports about the task that had been performed with the item during encoding. Recollective experience was enhanced for emotional compared to neutral photos after a 24-h delay, but not immediately after encoding. In contrast, memory for the task performed during encoding did not differ between emotional and neutral photos at either time point. The findings indicate that emotion slows the effects of forgetting on the recollective experience associated with studied events, without necessarily slowing the forgetting of specific contextual details of those events.
有观点认为，情绪通过增强记忆巩固的机制来减缓遗忘。在此，我们研究这种随时间变化的过程是否会影响回忆的主观体验以及检索学习事件特定情境细节的能力。为此，我们在两个保留间隔时间点考察了对情感图片和中性图片的识别，并收集了“记得/知道”报告以及关于编码期间与该项目相关任务的报告。与中性照片相比，在24小时延迟后，情感照片的回忆体验增强，但在编码后立即没有增强。相比之下，在两个时间点上，情感图片和中性图片在编码期间执行任务的记忆并无差异。研究结果表明，情绪减缓了遗忘对与学习事件相关的回忆体验的影响，但不一定减缓对这些事件特定情境细节的遗忘。
