Attention mediates the flexible allocation of visual working memory resources.

SM Emrich, HA Lockhart… - Journal of Experimental …, 2017 - psycnet.apa.org
Though it is clear that it is impossible to store an unlimited amount of information in visual
working memory (VWM), the limiting mechanisms remain elusive. While several models of …

[HTML][HTML] Electrophysiological correlates of the flexible allocation of visual working memory resources

C Salahub, HA Lockhart, B Dube, N Al-Aidroos… - Scientific Reports, 2019 - nature.com
Visual working memory is a brief, capacity-limited store of visual information that is involved
in a large number of cognitive functions. To guide one’s behavior effectively, one must …

[HTML][HTML] A daytime nap enhances visual working memory performance and alters event-related delay activity

KJ MacDonald, HA Lockhart, AC Storace… - Cognitive, Affective, & …, 2018 - Springer
Working memory (WM) is impaired following sleep loss and may be improved after a nap.
The goal of the current study was to better understand sleep-related WM enhancement by: (1) …

Retrospective cue benefits in visual working memory are limited to a single location at a time

A DiPuma, HA Lockhart, SM Emrich… - Attention, Perception, & …, 2023 - Springer
Working memory (WM) performance can be improved by an informative cue presented during
storage. This effect, termed a retrocue benefit, can be used to study limits on how human …

[HTML][HTML] Reduced attentional control in older adults leads to deficits in flexible prioritization of visual working memory

SE Henderson, HA Lockhart, EE Davis, SM Emrich… - Brain Sciences, 2020 - mdpi.com
Visual working memory (VWM) resources have been shown to be flexibly distributed according
to item priority. This flexible allocation of resources may depend on attentional control, an …

Limitations on flexible allocation of visual short-term memory resources with multiple levels of goal-directed attentional prioritization

HA Lockhart, B Dube, KJ MacDonald… - Attention, Perception, & …, 2024 - Springer
Studies suggest that visual short-term memory (VSTM) is a continuous resource that can be
flexibly allocated using probabilistic cues that indicate test likelihood (ie, goal-directed …

Limits to the flexible re-distribution of visual working memory resources after encoding

B Dube, HA Lockhart, S Rak, S Emrich, N Al-Aidroos - 2019 - europepmc.org
Attention regulates visual working memory (VWM) performance by determining how its
resources are distributed among encoded information. During encoding, this process is both …

Reduced attentional control in older adults leads to deficits in flexible prioritization of visual working memory.

HA Lockhart, EE Davis, SE Henderson… - Journal of …, 2020 - jov.arvojournals.org
Visual working memory has been demonstrated to be flexibly distributed across sample
items depending on each item’s priority (Emrich, Lockhart, Al-Aidroos, 2017). This ability to …

Neural markers of visual working memory encoding and maintenance track attentional prioritization

C Salahub, HA Lockhart, B Dube, N Al-Aidroos… - Journal of …, 2019 - jov.arvojournals.org
There is a limit to how much information can be stored in visual working memory (VWM).
Previous models of this limitation have focused on the effects of VWM load, finding that …
