Noisy and hierarchical visual memory across timescales
Both in everyday life and in memory research, people tend to think that items are 'held'in

Semi-orthogonal subspaces for value mediate a binding and generalization trade-off
When choosing between options, we must associate their values with the actions needed to
select them. We hypothesize that the brain solves this binding problem through neural …

Map** visual working memory models to a theoretical framework
WXQ Ngiam - Psychonomic Bulletin & Review, 2024 - Springer
The body of research on visual working memory (VWM)—the system often described as a
limited memory store of visual information in service of ongoing tasks—is growing rapidly …

Meaningfulness and familiarity expand visual working memory capacity
Visual working memory is traditionally studied using abstract, meaningless stimuli. Although
studies using such simplified stimuli have been insightful in understanding the mechanisms …

Bayesian inference in ring attractor networks
A Kutschireiter, MA Basnak, RI Wilson… - Proceedings of the …, 2023 - National Acad Sciences
Working memories are thought to be held in attractor networks in the brain. These attractors
should keep track of the uncertainty associated with each memory, so as to weigh it properly …

The binding problem 2.0: beyond perceptual features
The “binding problem” has been a central question in vision science for some 30 years:
When encoding multiple objects or maintaining them in working memory, how are we able to …

The neural basis of swap errors in working memory
When making decisions in a cluttered world, humans and other animals often have to hold
multiple items in memory at once—such as the different items on a shop** list …

[HTML][HTML] Visual short-term memory binding and attentional processes during object-scene integration are preserved in mild cognitive impairment
Binding, a critical cognitive process likely mediated by attention, is essential for creating
coherent object representations within a scene. This process is vulnerable in individuals …

A dynamic neural resource model bridges sensory and working memory
Probing memory of a complex visual image within a few hundred milliseconds after its
disappearance reveals significantly greater fidelity of recall than if the probe is delayed by as …

Working memory as a representational template for reinforcement learning
Working memory (WM) and reinforcement learning (RL) both influence decision-making, but
how they interact to affect behaviour remains unclear. We assessed whether RL is …
