Individual Differences in Working Memory and the N2pc [PDF]
Frontiers in Human Neuroscience, 2021 The lateralized ERP N2pc component has been shown to be an effective marker of attentional object selection when elicited in a visual search task, specifically reflecting the selection of a target item among distractors.

Microsaccades strongly modulate but do not directly cause the EEG N2pc marker of spatial attention. [PDF]
PLoS BiologyThe N2pc is a popular human-neuroscience marker of covert and internal spatial attention that occurs 200-300 ms after being prompted to shift attention-a time window also characterized by the spatial biasing of small fixational eye movements known as ...

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.

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.

Dissociating between the N2pc and attentional shifting: An attentional blink study [PDF]
Neuropsychologia, 2018 The N2pc is routinely used as an electrophysiological index of attentional shifting. Its absence is thus taken as evidence that no shift of attention occurred. We provide evidence in contrast to this notion using a variant of the attentional blink (AB) paradigm.

A multilab investigation into the N2pc as an indicator of attentional selectivity: Direct replication of Eimer (1996) [PDF]
Cortex, 2023 The N2pc is widely employed as an electrophysiological marker of an attention allocation. This interpretation was largely driven by the observation of an N2pc elicited by an isolated relevant target object, which was reported as Experiment 2 in Eimer (1996).

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 ...

An early parietal ERP component of the frontoparietal system: EDAN≠N2pc [PDF]
Brain Research, 2010 Directing spatial attention or manual response selection by means of arrow cues elicits a characteristic sequence of lateralized ERP components. Van Velzen and Eimer (2003) proposed that one of these components, the EDAN (early directing-attention negativity) is not related to the control of spatial attention but is instead an N2pc in disguise, related

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.
