Further Evidence That N2pc Reflects Target Enhancement Rather Than Distracter Suppression [PDF]
Frontiers in Psychology, 2018 The N2-posterior-contralateral (N2pc) component is an index in the domain of event-related potentials for exploring the underlying mechanism of visual-spatial attention.

Measuring trust in artificial intelligence with the N2pc component
NeuroImageEfficient allocation of attentional resources is critical when humans collaborate with artificial intelligence (AI): they must focus on their task while monitoring the AI to intervene if it fails.

The Guidance of Attentional Selectivity in Visual Search Is Always Feature-Based: Behavioral and Electrophysiological Evidence From Feature and Conjunction Search Tasks. [PDF]
PsychophysiologyABSTRACT It is generally assumed that the guidance of attention in visual search operates in a feature‐based fashion, but this conclusion is mainly based on the results of search tasks with feature‐defined targets. Here, we investigated whether attentional templates may contain integrated object‐based representations in tasks where targets are defined ...

High-Frequency rTMS Improves Visual Working Memory in Patients With aMCI: A Cognitive Neural Mechanism Study. [PDF]
CNS Neurosci TherABSTRACT Background Visual working memory (VWM), which is an essential component of higher cognitive processes, declines with age and is associated with the progression from amnestic mild cognitive impairment (aMCI) to Alzheimer's disease (AD). Cognitive impairment, particularly in VWM, is prominent in aMCI and may indicate disease progression.

The N2pc component and stimulus duration [PDF]
NeuroReport, 2007 The N2pc component of the event-related potential is a moment-by-moment index of the deployment of visual-spatial attention. It is not clear whether the N2pc reflects pure top-down attentional activity or a positive interaction of top-down activity with bottom-up sensory activity.

Attention and prediction modulations in expected and unexpected visuospatial trajectories.
PLoS ONE, 2021 Humans are constantly exposed to a rich tapestry of visual information in a potentially changing environment. To cope with the computational burden this engenders, our perceptual system must use prior context to simultaneously prioritise stimuli of ...

The capacity limitations of multiple-template visual search during task preparation and target selection. [PDF]
PsychophysiologyAbstract Visual search is guided by mental representations of target‐defining features (attentional templates) that are activated in a preparatory fashion. It remains unknown how many templates can be maintained concurrently, and what kind of costs are associated with multiple‐template versus single‐template search.

Visual search and the N2pc in children [PDF]
Attention, Perception, & Psychophysics, 2015 While there is growing understanding of visual selective attention in children, some aspects such as selection in the presence of distractors are not well understood. Adult studies suggest that when presented with a visual search task, an enhanced negativity is seen beginning around 200 ms (the N2pc) that reflects selection of a target item among ...

The N2pc is increased by perceptual learning but is unnecessary for the transfer of learning. [PDF]
PLoS ONE, 2012 BACKGROUND: Practice improves human performance in many psychophysical paradigms. This kind of improvement is thought to be the evidence of human brain plasticity. However, the changes that occur in the brain are not fully understood.

EEG cortical network reveals the temporo-spatial mechanism of visual search
Brain Research Bulletin, 2023 This study aims to explore a method based on brain networks for implicit attention by using wavelet coherence as feature to identify individual targets in the visual field, find the optimal classification rhythm and time window, and investigate the ...
