TLDR
It is shown that individuals can monitor the status of information in working memory as it degrades over time and suggest that people have access to information reflecting the existence and quality of their working memories, and that they can use this information to guide their behavior.
Abstract
Confidence in our memories is influenced by many factors, including beliefs about the perceptibility or memorability of certain kinds of objects and events, as well as knowledge about our skill sets, habits, and experiences. Notoriously, our knowledge and beliefs about memory can lead us astray, causing us to be overly confident in eyewitness testimony or to overestimate the frequency of recent experiences. Here, using visual working memory as a case study, we stripped away all these potentially misleading cues, requiring observers to make confidence judgments by directly assessing the quality of their memory representations. We show that individuals can monitor the status of information in working memory as it degrades over time. Our findings suggest that people have access to information reflecting the existence and quality of their working memories, and furthermore, that they can use this information to guide their behavior.

Evolution in Mind: Evolutionary Dynamics, Cognitive Processes, and Bayesian Inference

TL;DR: Deep correspondences exist between the mathematics of evolution and of learning, with perhaps the deepest being an equivalence between certain evolutionary dynamics and Bayesian inference that permits reinterpretation of evolutionary processes as algorithms forBayesian inference and has relevance for understanding diverse cognitive capacities, including memory and creativity.

Strategic allocation of working memory resource.

TL;DR: This study shows that people have access to and utilize the quality of their memory when making decisions, and suggests that people are allocating resource according to behavioral relevance, but suggests that they are doing so with the aim of maximizing memory accuracy.

Visual short-term memory through the lifespan: Preserved benefits of context and metacognition.

TL;DR: Older adults retain their capacity to boost memory performance through attention to external context and monitoring of their performance, and strategies that focus on taking advantage of these preserved abilities may therefore help to maintain VSTM performance with advancing age.

Humans incorporate trial-to-trial working memory uncertainty into rewarded decisions

TL;DR: This work manipulates prior beliefs in a standard WM task to show that WM contains a representation of the trial-by-trial uncertainty of visual stimuli, and suggests that WM represents uncertainty information, and that this can be combined with prior beliefs.

How Working Memory and Reinforcement Learning Are Intertwined: A Cognitive, Neural, and Computational Perspective

TL;DR: The authors show that reinforcement learning and working memory are two core processes of human cognition and are often considered cognitively, neuroscientifically, and algorithmically distinct, but the brain networks that support them actually overlap significantly and that they are less distinct cognitive processes than often assumed.

Discrete fixed-resolution representations in visual working memory

TL;DR: It is shown that, when presented with more than a few simple objects, human observers store a high-resolution representation of a subset of the objects and retain no information about the others.
