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.

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.

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 ...

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.

Reward History and Statistical Learning Independently Impact Attention Search: An ERP Study [PDF]
Brain SciencesSelection history is widely accepted as a vital source in attention control. Reward history indicates that a learned association captures attention even when the reward is no longer presented, while statistical learning indicates that a learned ...

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 ...
