摘要

瞳孔动力学反映了视觉工作记忆的不同和重要操作的影响:编码、维持和优先级。在这里,我们回顾了瞳孔大小如何预测记忆表现,以及它如何为每种操作的机制提供新的见解。视觉信息必须首先以足够的精度编码到工作记忆中。这种编码过程的深度分别与唤醒相关的基线瞳孔大小以及刺激开始前后的瞳孔收缩反应有关。随后,随着时间的推移,对编码信息进行维护,以确保其不会丢失。瞳孔扩张反映了对信息的努力维护,其中存储更多的项目伴随着更大的扩张。最后,对与任务最相关的信息进行优先级排序,以指导即将发生的行为,这反映在另一个延迟组件中。此外,通过标记具有不同亮度水平的视觉信息,可以直接对记忆中的激活内容进行瞳孔测量。通过这种亮度标记机制,瞳孔光响应揭示了在编码和排序过程中,暗项目还是亮项目受到更多关注。总之,将瞳孔反应概念化为不同成分随时间的总和,揭示了对视觉工作记忆操作的见解。从这个角度来看,瞳孔测量是研究视觉工作记忆工作的最重要操作的一条很有前途的途径。本文分类为:心理学>注意力心理学>记忆心理学>理论与方法。

Revealing visual working memory operations with pupillometry: Encoding, maintenance, and prioritization.

Pupillary dynamics reflect effects of distinct and important operations of visual working memory: encoding, maintenance, and prioritization. Here, we review how pupil size predicts memory performance and how it provides novel insights into the mechanisms of each operation. Visual information must first be encoded into working memory with sufficient precision. The depth of this encoding process couples to arousal-linked baseline pupil size as well as a pupil constriction response before and after stimulus onset, respectively. Subsequently, the encoded information is maintained over time to ensure it is not lost. Pupil dilation reflects the effortful maintenance of information, wherein storing more items is accompanied by larger dilations. Lastly, the most task-relevant information is prioritized to guide upcoming behavior, which is reflected in yet another dilatory component. Moreover, activated content in memory can be pupillometrically probed directly by tagging visual information with distinct luminance levels. Through this luminance-tagging mechanism, pupil light responses reveal whether dark or bright items receive more attention during encoding and prioritization. Together, conceptualizing pupil responses as a sum of distinct components over time reveals insights into operations of visual working memory. From this viewpoint, pupillometry is a promising avenue to study the most vital operations through which visual working memory works. This article is categorized under: Psychology > Attention Psychology > Memory Psychology > Theory and Methods.
