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 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 ...

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 ...

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.

Event-related potentials dissociate effects of salience and space in biased competition for visual representation. [PDF]
PLoS ONE, 2010 BACKGROUND: Selective visual attention is the process by which the visual system enhances behaviorally relevant stimuli and filters out others.

Express attentional re-engagement but delayed entry into consciousness following invalid spatial cues in visual search. [PDF]
PLoS ONE, 2008 BACKGROUND: In predictive spatial cueing studies, reaction times (RT) are shorter for targets appearing at cued locations (valid trials) than at other locations (invalid trials). An increase in the amplitude of early P1 and/or N1 event-related potential (

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.
