Examining the lateralization of electrophysiological correlates of auditory awareness

open access: yesPsychophysiology, Volume 61, Issue 11, November 2024.
Abstract The neurological basis for perceptual awareness remains unclear, and theories disagree as to whether sensory cortices per se generate awareness. Critically, neural activity in the sensory cortices is only a neural correlate of consciousness (NCC) if it closely matches the contents of perceptual awareness.

The guidance of spatial attention during visual search for colour combinations and colour configurations [PDF]

open access: yes, 2016
Representations of target-defining features (attentional templates) guide the selection of target objects in visual search. We used behavioural and electrophysiological measures to investigate how such search templates control the allocation of attention

Target switch costs in visual search arise during the preparatory activation of target templates

open access: yesPsychophysiology, Volume 61, Issue 11, November 2024.
Abstract Prior research on task switching has shown that the reconfiguration of stimulus–response mappings across trials is associated with behavioral switch costs. Here, we investigated the effects of switching representations of target‐defining features in visual search (attentional templates).

Acute Exposure to the Cold Pressor Stress Impairs Working Memory Functions: An Electrophysiological Study

open access: yesFrontiers in Psychiatry, 2020
The results of previous literature focusing on the effects of acute stress on human working memory (WM) are equivocal. The present study explored the effects of acute stress on human WM processing using event-related potential (ERP) techniques.

The control of attentional target selection in a colour/colour conjunction task [PDF]

open access: yes, 2016
To investigate the time course of attentional object selection processes in visual search tasks where targets are defined by a combination of features from the same dimension, we measured the N2pc component as an electrophysiological marker of ...

A new method for tracking the preparatory activation of target templates for visual search with high temporal precision

open access: yesPsychophysiology, Volume 61, Issue 8, August 2024.
Abstract Efficiently selecting task‐relevant objects during visual search depends on foreknowledge of their defining characteristics, which are represented within attentional templates. These templates bias attentional processing toward template‐matching sensory signals and are assumed to become anticipatorily activated prior to search display onset ...

Electrophysiological Evidence of a Delay in the Visual Recognition Process in Young Children [PDF]

open access: yes, 2015
The present study analyzes the development of the visual recognition processing of the relevant stimulus in a Delayed Match-To-Sample (DMS) task during the matching phase.

ERPs and alpha oscillations track the encoding and maintenance of object‐based representations in visual working memory

open access: yesPsychophysiology, Volume 61, Issue 7, July 2024.
Abstract When memorizing an integrated object such as a Kanizsa figure, the completion of parts into a coherent whole is attained by grouping processes which render a whole‐object representation in visual working memory (VWM). The present study measured event‐related potentials (ERPs) and oscillatory amplitudes to track these processes of encoding and ...

Electrophysiological Correlates of Subitizing in Healthy Aging.

open access: yesPLoS ONE, 2015
To understand the nature of age-related changes in enumeration abilities we measured two ERP responses -N2pc and CDA, associated respectively to attentive individuation and VWM- and posterior alpha band (8-15 Hz) event-related desynchronization (ERD ...

Different neural mechanisms for nonsalient trained stimuli and physically salient stimuli in visual processing

open access: yesPsyCh Journal, Volume 13, Issue 2, Page 227-241, April 2024.
Abstract Previous studies have shown that nonsalient trained stimuli could capture attention and would be actively suppressed when served as distractors. However, it was unclear whether nonsalient trained stimuli and physically salient stimuli operate through the same attentional neural mechanism.
