Investigating word order processing using pupillometry and event-related potentials
… using a psychophysiological measure known as pupillometry as well as Event-Related Potentials (ERP). The scope of the the- sis was broad, investigating the processing of several different movement constructions with native speakers of English and second language learners of English, as well as …

Measuring children’s sensitivity to phonological detail using eye tracking and pupillometry
… paradigms suitable for infants: single-picture pupillometry and intermodal preferential looking. Such paradigms have the potential to uncover lexical knowledge that may be masked otherwise due to cognitive limitations. The study reported in Chapter 2 obtained a differential response in pupil …

Distinguishing moral disgust and anger using pupillometry and responses to economic behaviours
… distinguishing moral disgust from moral anger: pupillometry and an economic game. First, across two studies, we found that self- reported feelings of disgust, but not anger, predicted significant pupil dilation to emotionally engaging sounds and images. Second, we used this method to investigate …

A Neurophysiological Investigation of Listening Effort in Normal Hearing Adults Using fNIRS and Pupillometry
… increasing cognitive demand. I proposed that pupillometry can be used to characterize the cortical response, such that changes in pupil size would be associated with neural activation that directly relates to effortful processing. The primary goal of this study was to investigate the …

Investigating pupillometry as a novel mechanism for detecting emotional regulation difficulties in individuals with PTSD
Objective: Individuals with posttraumatic stress disorder (PTSD) have been found to exhibit emotional regulation difficulties. However, much remains to be learned about the specific neural mechanisms that underlie such difficulties. This study aimed to use eye tracking to investigate the mechanisms …

A Window Into Autonomic Nervous System Functioning in Autism: Pupillometry in Adults on the Autism Spectrum
… symptoms of depression and anxiety? Pupillometry and symptom measures were conducted with a sample of adults on the autism spectrum (N=11) and adults without a diagnosis of autism (N=14). Primary variables were baseline pupil diameter, amplitude of dilation/constriction, latency to …

Emotion versus Motivation: Probing Dissociable Effects on Cognitive Control Through Task Performance, Pupillometry Methods, and Individual Differences
… performance was measured using high-resolution pupillometry as a secondary, high temporal-resolution measure of cognitive dynamics, and individual difference measures: both personality and cognition-related) were collected to examine whether the effects of emotional and motivational …

Exploring the utility of pupillometry as a biomarker for relationships between early life stress, emotion regulation, and cognition
… tools are not readily available. Recently, pupillometry has been recognised as a novel, non-invasive approach to identify potential abnormalities in cognitive and emotional functioning linked to ELS and stress-induced alterations in the locus coeruleus-norepinephrine (LC-NE) pathway. …

Simply (neuro-)stimulating: The effects of transcutaneous vagus nerve stimulation on phonological and lexical tone learning indexed by behavior and pupillometry
… as was physiological data in the form of pupillometry due to its ties both to cognitive effort and the most well-studied taVNS mechanism of action, the production of norepinephrine. Active taVNS groups received stimulation before or during multiple training and testing tasks across the two …

Extra-Linguistic Factors in Langauge Comprehension
… measures. Online measures, such as EEG or pupillometry, have not been included until recently. Pupillometry, which involves measuring the size of the pupil, is considered a reliable indicator of cognitive effort during language comprehension. Hubert-Lyall and Järvikivi are unique in their …

Virtual Reality Based System for Measurement and Interpretation of Pupillary Function
… cognitive load, fatigue, and focus. Traditional pupillometry techniques such as, infrared cameras, eye-tracking glasses etc., however, can be time-consuming, expensive, and invasive. These techniques can be painful or uncomfortable for the individual, which would decrease compliance and possibly …

Influence of Head Impact Exposure on Oculomotor Function and Pupillary Light Reflexes in Men and Women Soccer Players
… can be quantified via oculomotor function and pupillometry. Currently, King Devick (KD) style tests and Pupillary Light Reflex (PLR) are two popular tests that can be administered to athletes to gather clinical eye measures relating to oculomotor function and pupillometry. This study aimed to …

The influence of arousal on visuocortical processing in humans
… processing, this work comprised a series of pupillometry and functional magnetic resonance imaging (fMRI) experiments aimed to untangle the influence of cognitive and emotional arousal on contrast processing in human early visual cortex (V1-V3). The goal of the first two experiments was to …

Evaluating cognitive workload in an AR environment using pupil area responses
… learners' cognitive workload, using pupil-area pupillometry synchronized with established subjective measures. Participants engaged with biomechanics-focused AR modules while wearing eye-tracking glasses, enabling continuous recording of their pupil responses during both learning and …

Central and peripheral mechanisms of pain modulationthe role of the Locus coeruleus and pupillary dynamics in neuropathic and inflammatory pain
… The second study implemented longitudinal pupillometry in male and female mice following CCI to characterize the temporal evolution of pupil dynamics and to identify possible sex-dependent differences. Pupil recordings were obtained, in anaesthetized animals, under controlled conditions at …

Exploring non-clinical inattention in adults: prevalence, and links to working memory and self-regulation.
… four further studies we used behavioural and pupillometry measures to investigate the cognitive underpinnings of inattention with a view to differentiating it from hyperactivity and impulsivity. Research suggests a role for executive functions (EFs) and self-regulatory processes in ADHD, …

EEG theta oscillations during sleep deprivation
… conducted extensive questionnaires and collected pupillometry data. I found that sdTheta can be widespread across the brain, although the specific sources depend on the ongoing task. Curiously, theta mostly originated from areas not critical for the task. I found that sdTheta occurs in bursts, …

Implicit learning as a mechanism for syntactic acquisition and processing: Evidence from syntactic priming.
… thesis explored combining syntactic priming with pupillometry, a real-time psychophysiological measure. The implicit error-based learning account proposes a cognitive architecture that is continuous from children to adults, linking syntactic acquisition in children to syntax processing in adults. …
