Attentional Selection and Allocation to Alarm Signals in Complex Environments: The New Electrophysiological Evidence [PDF]

open access: yesBrain Sciences
Background/Objectives: This study explore attentional selection and allocation during alarm signal processing in complex environments. Methods: Adopting the dual-task paradigm combining Visual Alarm Task and Main Task with EEG recording, a total of 120 ...

Вклад различных пространственных модуляций в управление экзогенным вниманием: исследование методом N2pc

open access: yesРоссийский психологический журнал, 2022
Введение. Механизмы экзогенного внимания, обладая высокой чувствительностью к физическим характеристикам сенсорных сигналов, обеспечивают первичную адаптацию к окружающей среде.

The capacity limitations of multiple-template visual search during task preparation and target selection. [PDF]

open access: yesPsychophysiology
Abstract Visual search is guided by mental representations of target‐defining features (attentional templates) that are activated in a preparatory fashion. It remains unknown how many templates can be maintained concurrently, and what kind of costs are associated with multiple‐template versus single‐template search.

Temporal dynamics of emotional face processing in social anxiety. [PDF]

open access: yesPLoS ONE
Previous 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 ...

N2pc is modulated by stimulus–stimulus, but not by stimulus–response incompatibilities

open access: yesBiological 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.

A neural network predicting the amplitude of the N2pc in individual EEG datasets [PDF]

open access: yesJournal of Neural Engineering, 2021
Abstract Objective. The N2pc is a small amplitude transient interhemispheric voltage asymmetry used in cognitive neuroscience to investigate subject’s allocation of selective visuo-spatial attention. N2pc is typically estimated by averaging the sweeps of the electroencephalographic (EEG) signal

The neural correlates of attentional bias in blood phobia as revealed by the N2pc [PDF]

open access: yesSocial Cognitive and Affective Neuroscience, 2009
In the literature, a lack of attentional bias in blood phobia has been reported, using both behavioral and ERP measures. However, in the tasks employed so far, attentional resources to single stimuli, rather than attentional selection, were evaluated. The present study investigated whether in blood phobics disorder-relevant pictures can capture visuo ...

Further Evidence That N2pc Reflects Target Enhancement Rather Than Distracter Suppression

open access: yesFrontiers in Psychology, 2018
The N2-posterior-contralateral (N2pc) component is an index in the domain of event-related potentials for exploring the underlying mechanism of visual-spatial attention.

Electrical brain activations in preadolescents during a probabilistic reward-learning task reflect cognitive processes and behavior strategies [PDF]

open access: yesFrontiers in Human Neuroscience
Both 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

open access: yesPsychophysiology, 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.
