Fundamental bound on the persistence and capacity of short-term memory stored as graded persistent activity by Koyluoglu, O, Pertzov, Y, Manohar, S, Husain, M, Fiete, I

“…Yet, as we show, the degradation of information stored directly in such networks behaves differently from human short-term memory performance. …”

Working memory for sequences of temporal durations reveals a volatile single-item store by Manohar, S, Husain, M

Development of visual working memory precision in childhood. by Burnett Heyes, S, Zokaei, N, van der Staaij, I, Bays, P, Husain, M

“…Developmental studies have suggested an increase during childhood in the maximum number of complete items that can simultaneously be stored in VWM. Here, we exploit a recent theoretical and empirical innovation to investigate instead the precision with which items are stored in VWM, where precision is a continuous measure reflecting VWM resolution. …”

Longitudinal development of visual working memory precision in childhood and early adolescence by Burnett Heyes, S, Zokaei, N, Husain, M

“…Results show age-related improvement in recall precision on both 1-item and 3-item VWM tasks, suggesting development during childhood and early adolescence in the resolution with which both single and multiple items are stored in VWM. Probabilistic modelling of response distribution data suggests age-related improvement in precision is attributable to a specific decrease in the variability (noisiness) of stored feature representations. …”

Causes and consequences of limitations in visual working memory. by Fallon, S, Zokaei, N, Husain, M

“…A large corpus of evidence now suggests that there might not be a hard limit on the number of items that can be stored. Instead, WM may be better captured by a highly limited––but flexible––resource model. …”

Dopamine alters the fidelity of working memory representations according to attentional demands by Fallon, S, Zokaei, N, Norbury, A, Manohar, S, Husain, M

“…By applying a stochastic model of response selection, we established that the causes of drug-induced changes in performance were due to changes in the precision with which items were stored in WM. However, there was no change in the extent to which distractors were mistaken for targets. …”

Short-term memory for spatial, sequential and duration information by Manohar, S, Pertzov, Y, Husain, M

“…Some argue that they are crucial contexts within which other stored features are embedded, allowing binding of information that belongs together within STM. …”

Maintaining internal representations: the role of the human superior parietal lobe. by Wolpert, D, Goodbody, S, Husain, M

“…These models predict that an internal state estimate is maintained or stored in the brain. Here we report a patient with a lesion of the superior parietal lobe who shows both sensory and motor deficits consistent with an inability to maintain such an internal representation between updates. …”

The precision of visual working memory is set by allocation of a shared resource. by Bays, P, Catalao, R, Husain, M

“…One account proposes a small number of memory "slots," each capable of storing a single visual object with fixed precision. …”

Temporal dynamics of encoding, storage, and reallocation of visual working memory. by Bays, P, Gorgoraptis, N, Wee, N, Marshall, L, Husain, M

“…No evidence was observed for a limit on the number of items stored. Cuing one display item with a brief flash led to rapid development of a recall advantage for that item. …”

Temporal dynamics of encoding, storage, and reallocation of visual working memory by Bays, P, Gorgoraptis, N, Wee, N, Marshall, L, Husain, M

“…No evidence was observed for a limit on the number of items stored. Cuing one display item with a brief flash led to rapid development of a recall advantage for that item. …”

Rapid forgetting results from competition over time between items in visual working memory. by Pertzov, Y, Manohar, S, Husain, M

“…However, despite its significance, the mechanisms underlying rapid forgetting remain unclear, with intense recent debate as to whether it is interference between stored items that leads to loss of information or simply temporal decay. …”

Dynamic updating of working memory resources for visual objects. by Gorgoraptis, N, Catalao, R, Bays, P, Husain, M

“…These results support the view that WM resources can be dynamically and flexibly updated as new items have to be stored, but redistribution of resources with the addition of new items is associated with misbinding object features, providing important constraints and a framework for interpreting neural data.…”

The graded fate of unattended stimulus representations in visuospatial working memory by Sahan, M, Dalmaijer, E, Verguts, T, Husain, M, Fias, W

“…These results demonstrate that unattended representations are prone to spatial confusions due to spatial degradation of binding strengths in WM, even though they are stored with the same representational quality.…”

Working memory in Alzheimer's disease and Parkinson's disease by Zokaei, N, Husain, M

“…This misbinding of features that belong to different objects in memory can be considered a form of interference between stored items. Such binding errors are evident even in presymptomatic individuals with familial AD (due to gene mutations) who do not have AD yet. …”

The role of attention in working memory by Dalmaijer, ES

“…Specifically, it fails to replicate the finding that resources are re-allocated to saccade targets, but it does find that the location of items is stored at a higher precision than items’ other features are. …”

Storage and binding of object features in visual working memory. by Bays, P, Wu, E, Husain, M

“…An influential conception of visual working memory is of a small number of discrete memory "slots", each storing an integrated representation of a single visual object, including all its component features. …”

Binding deficits in memory following medial temporal lobe damage in patients with voltage-gated potassium channel complex antibody-associated limbic encephalitis. by Pertzov, Y, Miller, T, Gorgoraptis, N, Caine, D, Schott, J, Butler, C, Husain, M

“…Crucially, their errors were strongly associated with an increased tendency to report the property of the wrong item stored in memory, rather than simple degradation of memory precision. …”
