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 ...

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.

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 ...

The Impact of State Depression on Proactive Control and Distractor Processing in a Memory Task: An Electrophysiological Study

open access: yesApplied Sciences
(1) Background: Individuals with high levels of state depression are hypothesized to have an impairment of attentional control functions necessary for filtering irrelevant information.

Towards the automated localisation of targets in rapid image-sifting by collaborative brain-computer interfaces. [PDF]

open access: yesPLoS 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 ...

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.

Dissociable event‐related potential modulations of intrinsic and extrinsic factors in temporal integration

open access: yesPsychophysiology, Volume 61, Issue 4, April 2024.
Abstract We investigated visual temporal integration, by which multiple stimuli appearing in rapid succession are perceived as a single event. Temporal integration not only depends intrinsically on the passage of time but also, extrinsically, on the number and distribution of successive stimuli that are presented across that time interval.

Peak occipital alpha frequency mediates the relationship between sporting expertise and multiple object tracking performance

open access: yesBrain and Behavior, Volume 14, Issue 2, February 2024.
Occipital peak alpha frequency mediates the relationship between sporting expertise and multiple object tracking performance. Abstract Background Multiple object tracking (MOT) is often used as a lab‐based paradigm for investigating goal‐driven attention as an indicator for “real‐world” attention in tasks such as sport.

Attentional Capture and Inhibition of Saccades after Irrelevant and Relevant Cues

open access: yesJournal of Ophthalmology, 2014
Attentional capture is usually stronger for task-relevant than irrelevant stimuli, whereas irrelevant stimuli can trigger equal or even stronger amounts of inhibition than relevant stimuli.

Maximizing signal‐to‐noise ratio and statistical power in ERP measurement: Single sites versus multi‐site average clusters

open access: yesPsychophysiology, Volume 61, Issue 2, February 2024.
Abstract One important decision in every event‐related potential (ERP) experiment is which electrode site(s) to use in quantifying the ERP component of interest. A common approach is to measure the ERP from a single electrode site, typically the site where the ERP component is largest.
