Measuring trust in artificial intelligence with the N2pc component

NeuroImage
Efficient 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]

Psychophysiology
ABSTRACT 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 ...

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.

High-Frequency rTMS Improves Visual Working Memory in Patients With aMCI: A Cognitive Neural Mechanism Study. [PDF]

CNS Neurosci Ther
ABSTRACT 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 capacity limitations of multiple-template visual search during task preparation and target selection. [PDF]

Psychophysiology
Abstract 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.

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 (

Changes of Attention during Value-Based Reversal Learning Are Tracked by N2pc and Feedback-Related Negativity

Frontiers in Human Neuroscience, 2017
Previously learned reward values can have a pronounced impact, behaviorally and neurophysiologically, on the allocation of selective attention. All else constant, stimuli previously associated with a high value gain stronger attentional prioritization ...

Temporal brain dynamics of multiple object processing: the flexibility of individuation. [PDF]

PLoS ONE, 2011
The ability to process concurrently multiple visual objects is fundamental for a coherent perception of the world. A core component of this ability is the simultaneous individuation of multiple objects. Many studies have addressed the mechanism of object

Perceptual grouping and visual enumeration. [PDF]

PLoS ONE, 2012
We used lateralized Event-Related Potential (ERP) measures - the N2pc and CDA/SPCN components - to assess the role of grouping by target similarity during enumeration.
