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 ...

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 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.

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.

Temporal dynamics of emotional face processing in social anxiety. [PDF]
PLoS ONEPrevious studies have demonstrated that emotional facial expressions influence attention and perception in individuals with social anxiety. However, the relative influence of positive versus negative expressions on distinct subprocesses of attention and ...

Electrical brain activations in preadolescents during a probabilistic reward-learning task reflect cognitive processes and behavior strategies [PDF]
Frontiers in Human NeuroscienceBoth adults and children learn through feedback to associate environmental events and choices with reward, a process known as reinforcement learning (RL). However, tasks to assess RL-related neurocognitive processes in children have been limited.

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.
