The impact of cognitive load on processing efficiency and performance effectiveness in anxiety: evidence from event-related potentials and pupillary responses
Sign Up to like & getrecommendations! Published in 2018 at "Experimental Brain Research"
DOI: 10.1007/s00221-018-05466-y
Abstract: Anxiety has been associated with poor attentional control, as reflected in lowered performance on experimental measures of executive attention and inhibitory control. Recent conceptualisations of anxiety propose that individuals who report elevated anxiety symptoms worry… read more here.

Pupillary Responses Obey Emmert’s Law and Co-vary with Autistic Traits
Sign Up to like & getrecommendations! Published in 2020 at "Journal of Autism and Developmental Disorders"
DOI: 10.1007/s10803-020-04718-7
Abstract: We measured the pupil response to a light stimulus subject to a size illusion and found that stimuli perceived as larger evoke a stronger pupillary response. The size illusion depends on combining retinal signals with… read more here.

Acute stress enhances pupillary responses to erotic nudes: Evidence for differential effects of sympathetic activation and cortisol

DOI: 10.1016/j.biopsycho.2018.07.005
Abstract: Chronic stress attenuates reproductive behavior in many species, but evidence regarding the impact of acute stress on human sexual arousability is insufficient. Stressor-specific effects might result from divergent roles of both stress response systems. Social… read more here.

Task-evoked pupil dilation and BOLD variance as indicators of locus coeruleus dysfunction

DOI: 10.1016/j.cortex.2017.09.025
Abstract: Pupillary responses during cognitive tasks are linked to functioning of the locus coeruleus (LC). The LC is an early site of abnormal tau deposition, which may contribute to key aspects of Alzheimer's disease (AD) pathophysiology.… read more here.

Pupillary dilation responses as a midlife indicator of risk for Alzheimer's disease: association with Alzheimer's disease polygenic risk

DOI: 10.1016/j.neurobiolaging.2019.09.001
Abstract: Locus coeruleus (LC) tau accumulation begins early. Targeting LC (dys)function might improve early identification for Alzheimer's disease (AD) risk. Pupillary responses during cognitive tasks are driven by the LC and index cognitive effort. Despite equivalent… read more here.

DOI: 10.1038/s41598-017-10303-3
Abstract: Chromatic pupillometry is an emerging method for evaluating ocular health that relies upon the differential stimulation of rods, cones, and intrinsically photosensitive retinal ganglion cells (ipRGCs). Although it has been investigated in conditions affecting the… read more here.

Pupillary responses to short-wavelength light are preserved in aging

DOI: 10.1038/srep43832
Abstract: With aging, less blue light reaches the retina due to gradual yellowing of the lens. This could result in reduced activation of blue light-sensitive melanopsin-containing retinal ganglion cells, which mediate non-visual light responses (e.g., the… read more here.

DOI: 10.1080/00222895.2020.1869681
Abstract: This study examined the effects of focus of attention (FOA) instructions on learning a dart throwing task, quiet eye duration (QED) and pupillary responses. Thirty-six novices (M age = 33.6, SD = 19.7) learned using… read more here.

DOI: 10.1098/rsos.240606
Abstract: Pupillary responses serve as sensitive indicators of cognitive processes, attentional shifts and decision-making dynamics. Our study investigates how directional uncertainty and target speed (VT) influence pupillary responses in a foveal tracking task involving the interception… read more here.

DOI: 10.1192/j.eurpsy.2025.1074
Abstract: Introduction Melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs) are critical regulators of circadian rhythms and various non-image-forming visual functions, such as the pupillary light reflex (PLR), which adjusts the amount of light entering the eye.… read more here.
