Spatial localization in target detection based on decoding N2pc component
Journal of Neuroscience Methods, 2022 The Gaze-independent BCI system is used to restore communication in patients with eye movement disorders. One available control mechanism is the utilization of spatial attention. However, spatial information is mostly used to simply answer the "True/False" target recognition question and is seldom used to improve the efficiency of target detection ...

Unconscious Attentional Capture Effect Can be Induced by Perceptual Learning
i-Perception, 2011 Previous ERP studies have shown that N2pc serves as an index for salient stimuli that capture attention, even if they are task irrelevant. This study aims to investigate whether nonsalient stimuli can capture attention automatically and unconsciously ...

The neural correlations of spatial attention and working memory deficits in adults with ADHD
NeuroImage: Clinical, 2019 Working memory impairment is a typical cognitive abnormality in patients with attention-deficit/hyperactivity disorder (ADHD) and is closely related to attention.

Attentional bias modification in social anxiety: Effects on the N2pc component [PDF]
Behaviour Research and Therapy, 2019 Several meta-analyses to date have confirmed the efficacy of attentional bias modification (ABM) in shifting reaction times away from threatening stimuli, reducing anxiety symptoms, and buffering against stressor vulnerability. The reliability of reaction time differences, however, has been found to show unacceptable psychometric properties.

Working memory content guides attention
Journal of Pacific Rim Psychology, 2021 Previous studies showed that working memory (WM) content can guide attention; however, whether working memory capacity (WMC) and state anxiety could affect this remains unclear. This study aimed to examine the effect of WMC and state anxiety on attention

The Simon effect modulates N2cc and LRP but not the N2pc component
International Journal of Psychophysiology, 2012 Previous studies have reported that the horizontal arrangement of the stimuli in Simon tasks elicits three different components: LRP, N2pc and N2cc. Although N2cc may play a key role in Simon tasks, as it is involved in preventing responses based on stimulus position, modulation of the N2cc component according to the experimental conditions has not ...

Fast detection of covert visuospatial attention using hybrid N2pc and SSVEP features [PDF]
, 2016 ObjectiveDetecting the shift of covert visuospatial attention (CVSA) is vital for gaze-independent brain-computer interfaces (BCIs), which might be the only communication approach for severely disabled patients who cannot move their eyes.

Temporal dynamics of visual attention measured with event-related potentials. [PDF]
PLoS ONE, 2013 How attentional modulation on brain activities determines behavioral performance has been one of the most important issues in cognitive neuroscience. This issue has been addressed by comparing the temporal relationship between attentional modulations on ...

Neural Processing of Cognitive Control in an Emotionally Neutral Context in Anxiety Patients
Brain Sciences, 2021 Impaired cognitive control plays a crucial role in anxiety disorders and is associated with deficient neural mechanisms in the fronto-parietal network. Usually, these deficits were found in tasks with an emotional context.

The development of attentional control mechanisms in multisensory environments
Developmental Cognitive Neuroscience, 2021 Outside the laboratory, people need to pay attention to relevant objects that are typically multisensory, but it remains poorly understood how the underlying neurocognitive mechanisms develop.
