The psychophysics of human three-dimensional active visuospatial problem-solving

open access: yesScientific Reports, 2023
Our understanding of how visual systems detect, analyze and interpret visual stimuli has advanced greatly. However, the visual systems of all animals do much more; they enable visual behaviours.

Muscarinic Versus Nicotinic Modulation of a Visual Task A PET Study Using Drug Probes [PDF]

open access: yesNeuropsychopharmacology, 2001
Little is known about acetylcholine (ACh) modulation of central visual processing in humans. Receptor densities in visual brain regions are differentially distributed suggesting that receptor subtypes have different functions. Using PET, we have previously described the brain regions activated by a simple pattern-flash stimulus in healthy elderly ...

The association between negative attention biases and symptoms of depression in a community sample of adolescents [PDF]

open access: yesPeerJ, 2015
Adolescence is a vulnerable time for the onset of depression. Recent evidence from adult studies suggests not only that negative attention biases are correlated with symptoms of depression, but that reducing negative attention biases through training can

How Does Fearful Emotion Affect Visual Attention?

open access: yesFrontiers in Psychology, 2021
It has long been suggested that emotion, especially threatening emotion, facilitates early visual perception to promote adaptive responses to potential threats in the environment.

Measuring Biases of Visual Attention: A Comparison of Four Tasks

open access: yesBehavioral Sciences, 2020
Attention biases to stimuli with emotional content may play a role in the development and maintenance of anxiety disorders. The most commonly used tasks in measuring and treating such biases, the dot-probe and spatial cueing tasks, have yielded mixed ...

Convergent individual differences in visual cortices, but not the amygdala across standard amygdalar fMRI probe tasks [PDF]

open access: yesNeuroImage, 2017
The amygdala (AMG) has been repeatedly implicated in the processing of threatening and negatively valenced stimuli and multiple fMRI paradigms have reported personality, genetic, and psychopathological associations with individual differences in AMG activation in these paradigms.

Limited generalisation of changes in attentional bias following attentional bias modification with the visual probe task [PDF]

open access: yesCognition and Emotion, 2015
Although attentional bias modification (ABM) can change anxiety, recent studies failed to replicate such effects, possibly because the visual probe ABM failed to induce changes in attentional bias (AB). We investigated whether visual probe ABM generalised to different measures of AB besides the visual probe task (VPT), and thus whether ABM genuinely ...

Load-Dependent Increases in Delay-Period Alpha-Band Power Track the Gating of Task-Irrelevant Inputs to Working Memory

open access: yesFrontiers in Human Neuroscience, 2017
Studies exploring the role of neural oscillations in cognition have revealed sustained increases in alpha-band power (ABP) during the delay period of verbal and visual working memory (VWM) tasks. There have been various proposals regarding the functional

The Sternberg Paradigm: Correcting Encoding Latencies in Visual and Auditory Test Designs

open access: yesVision, 2021
The Sternberg task is a widely used tool for assessing the working memory performance in vision and cognitive science. It is possible to apply a visual or auditory variant of the Sternberg task to query the memory load.

Facial motion engages predictive visual mechanisms. [PDF]

open access: yesPLoS ONE, 2014
We employed a novel cuing paradigm to assess whether dynamically versus statically presented facial expressions differentially engaged predictive visual mechanisms.
