Attention selection, distractor suppression and N2pc
Cortex, 2009N2pc is generally interpreted as the electrocortical correlate of the distractor-suppression mechanisms through which attention selection takes place in humans. Here, we present data that challenge this common N2pc interpretation. In Experiment 1, multiple distractors induced greater N2pc amplitudes even when they facilitated target identification ...

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.

N2pc is modulated by stimulus–stimulus, but not by stimulus–response incompatibilities
Biological Psychology, 2013 Studies of the N2pc in Simon-type tasks have revealed inconsistent results. That is, N2pc was only modulated when a stimulus-stimulus (S-S) overlap covaries with the stimulus-response (S-R) overlap. The present study aimed to establish whether N2pc is modulated by the S-R or by the S-S overlap.

Reorienting of spatial attention in gaze cuing is reflected in N2pc
Social Neuroscience, 2011Research has shown that gaze cuing of attention is reflected in the modulation of P1 and N1 components of ERPs time-locked to target onset. Studies focusing on cue-locked analyses have produced mixed results. The present study examined ERP reflections of gaze cuing in further detail by recording electric brain activity from the scalp of participants ...

Effect of cue–target interval on the N2pc
NeuroReport, 2006The N2pc component of the event-related potential occurs when participants must select and process a lateralized visual target, often in the presence of one or more distractors. The goal of this research was to determine whether the N2pc reflects unique processing related to the treatment of the target or whether it reflects processing related to the ...

The effect of modulating top-down attention deployment on the N2pc/PCN
Biological Psychology, 2016The N2pc (PCN) component of the event-related potential (ERP) waveform provides a useful tool for directly assessing the locus of spatial attention in visual search. It is still unclear whether the amplitude of the N2pc/PCN relates to the deployment of attentional resources.

Reward expectation modulates N2pc for target selection: Electrophysiological evidence
Psychophysiology, 2021AbstractIn an electrophysiological experiment, we investigated the effect of reward expectation on the localized attentional interference effect using a cue‐target paradigm, while event‐related potentials (ERPs) were recorded. A cue indicating the reward condition of each trial (incentive vs.

Stimulus intensity affects the latency but not the amplitude of the N2pc
NeuroReport, 2007The N2pc component of the event-related potential (ERP) is an index of visual-spatial attention. It is not clear whether the N2pc reflects pure top-down attentional activity or an interaction of top-down activity with bottom-up sensory activity. Here, we manipulated stimulus intensity of the items composing the target display. Although the amplitude of

Modelling the N2pc and Its Interaction with Value
2007Attention and emotion are closely interlinked and recent results have shown some of the neuro-physiological details of the effects of attention on emotion through the distractor devaluation (DD) effect. We develop a possible neural attention control architecture to explain the DD effect, and show by specific simulation how the N2pc (an early component ...

The N2pc component reliably captures attentional bias in social anxiety
Psychophysiology, 2017 AbstractWe systematically compared different measures of attentional bias (i.e., reaction times, the N2pc component in the EEG, and explicit stimulus ratings) on their ability to reveal attentional engagement to threatening versus neutral facial stimuli in a Dot Probe Task and tested their relation to trait measures of general and social anxiety.
