Lexis or parsing? A corpus-based study of syntactic complexity and its effect on disfluencies in interpreting [PDF]
, 2018 Cognitive load is probably one of the most cited topics in research on simultaneous interpreting, but it is still poorly understood due to the lack of proper empirical tests.

Alzheimer's &Dementia, Volume 21, Issue S3, December 2025.Abstract Background The locus coeruleus (LC) is an early site of neurodegeneration in Alzheimer's disease. Its health and functional status are important correlates of, and potentially mediators of, disease progression. Improving the functional health of the LC may be possible using transcutaneous auricular vagus nerve stimulation (taVNS) to modulate ...

Pupil light reflex evoked by light-emitting diode and computer screen: methodology and association with need for recovery in daily life [PDF]
, 2018 Objectives: Pupil light reflex (PLR) has been widely used as a method for evaluating parasympathetic activity. The first aim of the present study is to develop a PLR measurement using a computer screen set-up and compare its results with the PLR ...

Pupillometry as tool to assess cognitive and affective processing in aging
Brain DisordersThe present manuscript synthesizes research using pupillometry to assess cognitive and affective processing in the aging population. There are two main findings: first, pupil size tends to enlarge as the cognitive load increases in older adults and a ...

Sympathetic and Parasympathetic Modulation of Pupillary Unrest
Frontiers in Neuroscience, 2020 Pupillary unrest is an established indicator of drowsiness or sleepiness. How sympathetic and parasympathetic activity contribute to pupillary unrest is not entirely unclear.

Attention Mobilization as a Modulator of Listening Effort: Evidence From Pupillometry
Trends in HearingListening to speech in noise can require substantial mental effort, even among younger normal-hearing adults. The task-evoked pupil response (TEPR) has been shown to track the increased effort exerted to recognize words or sentences in increasing noise ...

Evaluation of Cholinergic Deficiency in Preclinical Alzheimer’s Disease Using Pupillometry
Journal of Ophthalmology, 2017 Cortical cholinergic deficiency is prominent in Alzheimer’s disease (AD), and published findings of diminished pupil flash response in AD suggest that this deficiency may extend to the visual cortical areas and anterior eye.

Using Pupil Diameter to Measure Cognitive Load
, 2018 In this paper, we will present a method for measuring cognitive load and online real-time feedback using the Tobii Pro 2 eye-tracking glasses. The system is envisaged to be capable of estimating high cognitive load states and situations, and adjust human-
