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 ...

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.

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

Preserved suppression of salient irrelevant stimuli during visual search in Age-Associated Memory Impairment [PDF]
Frontiers in Psychology, 2016 Previous studies have suggested that older adults with age-associated memory impairment (AAMI) may show a significant decline in attentional resource capacity and inhibitory processes in addition to memory impairment.

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.

Towards the automated localisation of targets in rapid image-sifting by collaborative brain-computer interfaces. [PDF]
PLoS ONE, 2017 The N2pc is a lateralised Event-Related Potential (ERP) that signals a shift of attention towards the location of a potential object of interest. We propose a single-trial target-localisation collaborative Brain-Computer Interface (cBCI) that exploits ...

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 ...

Individual Differences in Working Memory and the N2pc
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.
