Statistically learned visual representations support visual working memory
Visual statistical learning (VSL) refers to the human ability to unintentionally extract statistical information from our environment. VSL has been proposed to have wide-reaching influence on a number of aspects of cognition. However, direct evidence that statistically learned information is used …

Visual working memory supports perceptual stability across saccadic eye movements
… movements. To create a stable perception of the visual world we must stitch together the gaps in visual input caused by this suppression. Early theories of perceptual stability proposed that information about the position of the eye could be used to cancel out changes in the retinal information …

Lifetime of Human Visual Sensory Memory: Properties and Neural Substrate
… the condition to measure the transient decay of visual sensory memory (VSM, also known as iconic memory). A model was developed to isolate the VSM and visual working memory (VWM) underlying the partial-report performance. The decay of VSM in each subject was well characterized by a single …

Age Differences in Working Memory Filtering of Distracting Information
… that as people age, cognitive processes such as visual working memory (VWM) performance decline. One potential explanation for this age-related decline in VWM is that older adults have decreased inhibitory control relative to younger adults. This impairs older adults’ ability to ignore irrelevant …

Investigating the Effects of Perceptual Complexity versus Conceptual Meaning on the Neural Correlates of Visual Working Memory
Previous research has demonstrated greater visual working memory (VWM) performance for real-world objects compared to simple features. Greater amplitudes of the contralateral delay activity (CDA) have also been noted for meaningful stimuli, despite being thought of as a neural marker of a fixed …

The Dissociation of Location and Object Working Memory Using Fmri and Meg
<p>Visual working memory (VWM) involves maintaining and processing visual information, often for the purpose of making immediate decisions. Neuroimaging experiments of VWM provide evidence in support of a neural system mainly involving a fronto-parietal neuronal network, but the role of specific …

Exploring the Relationship between Long-Term Memory and Attention through Attentional Templates
It is assumed that the contents of visual working memory (VWM) guide attention. This notion has been challenged by work which has demonstrated that multiple searches for the same target changes contralateral delay activity (CDA), an event-related potential that is the putative marker of the amount …

Visual Working Memory and Visual Selective Attention among Survivors of Pediatric Acute Lymphoblastic Leukemia (ALL)
… study investigated the relationship between visual working memory (VWM) and visual selective attention in survivors of pediatric acute lymphoblastic leukemia (ALL) either at high-risk or low-risk for neurocognitive impairments based on their treatment regimen and non-cancer controls. Previous …

The Effect of Aging on Object Representation
… through different cognitive paradigms probing visual working memory (vWM) and attention. OAs are known to demonstrate difficulties in these two cognitive domains, however, an under-researched in the aging field is the possible influence of the quality of representations in conjunction with the …

Change Detection In Rhesus Monkeys and Humans
<p>Visual working memory (VWM) is the temporary retention of visual information and a key component of cognitive processing. The classical paradigm for studying VWM and its encoding limitations has been change detection. Early work focused on how many items could be stored in VWM, leading to the …

Limitations of Human Visual Working Memory
… study investigates limitations of human visual working memory (VWM). The experiments of the present work involve the experimental paradigm of change detection using simple geometrical objects in the form of rectangles of different colour, length, and orientation. It can be shown, that a …

The contribution of visual working memory to priming of pop-out
… modulation, essentially eliminating the role of memory representation as an explanation for the underlying mechanism of PoP. The current study aimed to test this proposition to determine whether PoP is truly independent of guidance based on visual working memory (VWM) by adopting a dual-task …

Spatial and temporal processing biases in visual working memory in specific anxiety
… assumptions concerning anxiety-linked biased memory for threat are less convincing; based on the shared tendency for avoidance of deeper elaboration in anxiety disorders, some models predict memory biases only for implicit memory tasks (Williams et al., 1997) or even disclaim the relevance of …
