ABSTRACT

When they remember the same events, humans recollect common episodic traces. For making vividness judgements, older adults rely less than young adults on retrieved episodic details. Here, we examined the similarity of the subjective experience of remembering and the associated memory content across participants and we investigated age-effects. Young and older adults studied pictures associated with labels. At retrieval, participants judged the vividness of their memories and recalled pictures details. We examined the similarity of vividness judgements and memory recall across-participants. Across-participants similarity in vividness judgements was higher in young than in older adults, while no age-difference in the similarity of the richness of memory recall between participants was found. Together, these findings suggest that older adults’ vividness ratings are less similar from one participant to another than those of young adults, which may be explained by how older adults use memory details to frame their sense of memory vividness.

 抽象的

当人们记住相同的事件时，他们会回忆起常见的情景痕迹。为了做出生动性判断，老年人比年轻人更少依赖检索到的情景细节。在这里，我们检查了参与者的主观记忆体验和相关记忆内容的相似性，并调查了年龄效应。年轻人和老年人研究了与标签相关的图片。在检索时，参与者判断记忆的生动程度并回忆图片细节。我们检查了参与者之间生动性判断和记忆回忆的相似性。年轻人在生动性判断方面的跨参与者相似性高于老年人，而参与者之间记忆回忆丰富度的相似性没有发现年龄差异。总之，这些发现表明，与年轻人相比，老年人的生动度评级在一个参与者和另一个参与者之间不太相似，这可能是由于老年人如何使用记忆细节来构建他们的记忆生动度感。
