ABSTRACT

Episodic memory enables us to form a bank of autobiographical memories across our lifespan. The relationship between autobiographical memory and laboratory-measures of episodic memory is complicated and these processes might be differentially affected by ageing (e.g. Diamond et al., [2020]. Different patterns of recollection for matched real-world and laboratory-based episodes in younger and older adults. Cognition, 202, 104309.). Here, we examine whether the ability to recall one’s own visual perspective relates to richness of autobiographical recall, and how this relationship is affected by age. Memory of perspective at encoding, was assessed in younger (18–35 years) and older adults (65–85 years). Participants, wearing head cameras, viewed arrays of objects. Later they were asked which images represented earlier scenes, and if the image was taken from their perspective (i.e. from their camera). Performance was compared with autobiographical memory. Accuracy in identifying their own perspective correlated with autobiographical scores. Age-group was a moderating factor in this relationship. Subsequently, new participants encoded photographs of objects and were later asked whether they recognised the images. Visual perspective was manipulated in these photographs. In this task there was no relationship between performance and autobiographical memory. In younger adults only 3-D encoding of scenes relates directly to autobiographical memory but ability to complete these two tasks appears to operate independently in the older group.

摘要

情景记忆使我们能够在我们的一生中形成一个自传式记忆库。自传体记忆与情景记忆的实验室测量之间的关系很复杂，这些过程可能会受到衰老的不同影响（例如 Diamond 等人，[2020]。年轻人中匹配的现实世界和实验室事件的不同回忆模式和老年人。, 202, 104309.)。在这里，我们检查回忆自己的视觉视角的能力是否与自传回忆的丰富性有关，以及这种关系如何受年龄影响。在年轻人（18-35 岁）和老年人（65-85 岁）中评估了编码时的视角记忆。参与者戴着头戴式摄像机，查看对象阵列。后来他们被问到哪些图像代表了早期的场景，以及图像是否是从他们的角度（即从他们的相机）拍摄的。性能与自传记忆进行了比较。识别自己观点的准确性与自传分数相关。年龄组是这种关系的调节因素。随后，新参与者对物体的照片进行编码，然后被问及他们是否识别这些图像。在这些照片中操纵了视觉透视。在这项任务中，表现和自传体记忆之间没有关系。在年轻人中，只有场景的 3-D 编码与自传体记忆直接相关，但完成这两项任务的能力似乎在老年人中独立运作。
