Furious snarling: Teeth-exposure and anxiety-related attentional bias towards angry faces. [PDF]

open access: yesPLoS ONE, 2018
Dot-probe studies consistently show that high trait anxious individuals have an attentional bias towards threatening faces. However, little is known about the influence of perceptual confounds of specific emotional expressions on this effect.

The impact of aversive context on early threat detection in trauma exposed individuals and associations with post-traumatic stress symptoms

open access: yesJournal of Affective Disorders Reports, 2021
Introduction: Prolonged attentional bias to threat (AB) is associated with posttraumatic stress symptoms (PTSS). However, it is unclear whether this relationship extends to early threat detection (elicited by masked stimuli) and/or varies if AB is ...

The Rise and Fall of the Dot-Probe Task: Opportunities for Metascientific Learning

open access: yesSeeds of Science, 2022
Much of the extensive literature on spatial attentional bias is built on measurements using the dot-probe task. In recent years, concerns have been raised about the psychometric properties of bias scores derived from this task. The goal of the current paper is to look ahead and evaluate possible responses of the field to this situation from a ...

Do Carryover Effects Influence Attentional Bias to Threat in the Dot-Probe Task?

open access: yesJournal of Trial and Error, 2022
Threatening stimuli are often thought to have sufficient potency to bias attention, relative to neutral stimuli. Researchers and clinicians opt for frequently used paradigms to measure such bias, such as the dot-probe task.

Theoretical and Experimental Studies of Off-the-Shelf V-Dot Probes [PDF]

open access: yesIEEE Transactions on Plasma Science, 2018
This paper introduces the work undertaken to reliably use off-the-shelf differentiating voltage probes attached to coaxial transmission lines. The results obtained prove that indeed such probes are a valid and simple instrument for measuring nanosecond and subnanosecond voltage impulses.

Repulsive Aftereffects of Visual Space

open access: yesVision, 2023
Prolonged exposure to a sensory stimulus induces perceptual adaptation aftereffects. Traditionally, aftereffects are known to change the appearance of stimulus features, like contrast, color, or shape.

Peptide-Conjugated Quantum Dots Act as the Target Marker for Human Pancreatic Carcinoma Cells

open access: yesCellular Physiology and Biochemistry, 2016
Background/Aims: In the present study, we describe a novel and straightforward approach to produce a cyclic- arginine-glycine-aspartic (RGD)-peptide-conjugated quantum dot (QD) probe as an ideal target tumor biomarker.

Aging Impairs Disengagement From Negative Words in a Dot Probe Task. [PDF]

open access: yesFront Psychol, 2018
Age differences in emotional processes have been of great interest. Previous studies using the dot probe task show that older adults can be more influenced by negative emotionally valenced faces than younger adults. Subsequent work has demonstrated two distinctive ways people engage with stimuli in this task, namely orienting to and disengaging from ...

Monofunctional Quantum Dot Probes for Single-Molecule Imaging [PDF]

open access: yesBiophysical Journal, 2010
Recently, it has been shown that the optical properties of quantum dot (QDs) nanoparticles enable novel experiments at the single molecule level in live cells, thereby opening new prospects for the understanding of cellular processes. One difficulty with these experiments is that the complex biological environment imposes stringent design requirements ...
