A shared representation of order between encoding and recognition in visual short-term memory.
Many complex tasks require people to bind individual events into a sequence that can be held in short term memory (STM). For this purpose information about the order of the individual events in the sequence needs to be...
The use of commercial computerised cognitive games in older adults
Brain training programs are currently one effective solution to prevent cognitive decline in healthy aging. We conducted a meta-analysis of randomized controlled trials assessing the use of commercially available computerised...
Structural optimality and neurogenetic expression mediate functional dynamics in the human brain.
The human brain exhibits a rich functional repertoire in terms of complex functional connectivity patterns during rest and tasks. However, how this is developed upon a fixed structural anatomy remains poorly understood. Here we...

BACKGROUND: Alzheimer's disease and related forms of dementia are becoming increasingly prevalent with the aging of many populations. The diagnosis of Alzheimer's disease relies on tests to evaluate cognition and discriminate...

Working memory deficits are present in many neuropsychiatric diseases with diagnosis-related severity. However, it is unknown whether this common behavioral abnormality is a continuum explained by a neural mechanism shared...

Functional neuroimaging of the interference between working memory and the control of periodic ankle movement timing.
BACKGROUND: Limited information processing capacity in the brain necessitates task prioritisation and subsequent adaptive behavioural strategies for the dual-task coordination of locomotion with severe concurrent cognitive...
Visual recency bias is explained by a mixture model of internal representations.
Human bias towards more recent events is a common and well-studied phenomenon. Recent studies in visual perception have shown that this recency bias persists even when past events contain no information about the future. Reasons...
Drift in Neural Population Activity Causes Working Memory to Deteriorate Over Time.
Short-term memories are thought to be maintained in the form of sustained spiking activity in neural populations. Decreases in recall precision observed with increasing number of memorized items can be accounted for by a limit...

The neural basis of precise visual short-term memory for complex recognisable objects.
Recent evidence suggests that visual short-term memory (VSTM) capacity estimated using simple objects, such as colours and oriented bars, may not generalise well to more naturalistic stimuli. More visual detail can be stored in...
Cerebral cortex layer segmentation using diffusion magnetic resonance imaging in vivo with applications to laminar connections and working memory analysis.
Understanding the laminar brain structure is of great help in further developing our knowledge of the functions of the brain. However, since most layer segmentation methods are invasive, it is difficult to apply them to the...
Contralateral delay activity, but not alpha lateralization, indexes prioritization of information for working memory storage.
Working memory training and brain structure and function in extremely preterm or extremely low birth weight children.

This study in children born extremely preterm (EP; <28 weeks' gestational age) or extremely low birth weight (ELBW; <1,000 g) investigated whether adaptive working memory training using Cogmed® is associated with structural...

Huntington's disease patients display progressive deficits in hippocampal-dependent cognition during a task of spatial memory.
Kate L Harris, Matthew Armstrong, Rachel Swain, Sharon Erzinclioglu, Tilak Das, Neil Burgess, Roger A Barker, Sarah L Mason
Aug 22, 2019
BACKGROUND: Cognitive disturbances occur early in Huntington's disease (HD) and place a significant burden on the lives of patients and family members. Whilst these impairments are typically attributed to deterioration of the...
The repetition of errors in recall
Donald Laming
Aug 10, 2022
This review reanalyses the data from four experiments originally designed to test the fragmentation hypothesis. Participants were asked to recall triple or quadruple associates, cued by each of their components in turn, and to...
Why do participants initiate free recall of short lists of words with the first list item? Toward a general episodic memory explanation.

Internal but not external noise frees working memory resources.
The precision with which visual information can be recalled from working memory declines as the number of items in memory increases. This finding has been explained in terms of the distribution of a limited representational...

Recall is not necessary for verbal sequence learning.
The question of whether overt recall of to-be-remembered material accelerates learning is important in a wide range of real-world learning settings. In the case of verbal sequence learning, previous research has proposed that...
The experiential blink
The attentional blink (AB) represents a cognitive deficit in reporting the second of two targets (T2), when that second target appears 200-600 msec after the first (T1). However, it is unclear how this paradigm impacts the...
Scene memory and spatial inhibition in visual search

Feb 10, 2021
Any object-oriented action requires that the object be first brought into the attentional foreground, often through visual search. Outside the laboratory, this would always take place in the presence of a scene representation...
A neural model of retrospective attention in visual working memory.
An informative cue that directs attention to one of several items in working memory improves subsequent recall of that item. Here we examine the mechanism of this retro-cue effect using a model of short-term memory based on...
