A unified model of the task-evoked pupil response

CS Burlingham, S Mirbagheri, DJ Heeger - Science Advances, 2022 - science.org
The pupil dilates and reconstricts following task events. It is popular to model this task-
evoked pupil response as a linear transformation of event-locked impulses, whose …

Microsaccadic modulation evoked by emotional events

K Kashihara - Journal of Physiological Anthropology, 2020 - Springer
Saccadic eye movements can allude to emotional states and visual attention. Recent studies
have shown that microsaccadic responses (ie, small fixational eye movements) reflect …

[HTML][HTML] Decision making and oddball effects on pupil size: Evidence for a sequential process

C Strauch, I Koniakowsky, A Huckauf - Journal of cognition, 2020 - ncbi.nlm.nih.gov
In our physical environment as well as in many experimental paradigms, we need to decide
whether an occurring stimulus is relevant to us or not; further, stimuli have uneven …

Using microsaccades to estimate task difficulty during visual search of layered surfaces

AT Duchowski, K Krejtz, J Żurawska… - IEEE transactions on …, 2019 - ieeexplore.ieee.org
We develop an approach to using microsaccade dynamics for the measurement of task
difficulty/cognitive load imposed by a visual search task of a layered surface. Previous …

The Costs of Paying Overt and Covert Attention Assessed With Pupillometry

D Koevoet, C Strauch, M Naber… - Psychological …, 2023 - journals.sagepub.com
Attention can be shifted with or without an accompanying saccade (ie, overtly or covertly,
respectively). Thus far, it is unknown how cognitively costly these shifts are, yet such …

Acceleration of inferred neural responses to oddball targets in an individual with bilateral amygdala lesion compared to healthy controls

A Abivardi, CW Korn, I Rojkov, S Gerster… - Scientific Reports, 2023 - nature.com
Detecting unusual auditory stimuli is crucial for discovering potential threat. Locus coeruleus
(LC), which coordinates attention, and amygdala, which is implicated in resource …

Do pupillary responses during authentic slot machine use reflect arousal or screen luminance fluctuations? A proof-of-concept study

AJ Kim, WS Murch, EH Limbrick-Oldfield, MA Ferrari… - Plos one, 2022 - journals.plos.org
Modern slot machines are among the more harmful forms of gambling. Psychophysiological
measures may provide a window into mental processes that underpin these harms. Here we …

Pupillary responses reflect dynamic changes in multiple cognitive factors during associative learning in primates

Y Zhang, T Wang, W Dai, Y Li, Y Yang… - Journal of …, 2024 - Soc Neuroscience
Associative learning involves complex interactions of multiple cognitive factors. While adult
subjects can articulate these factors verbally, for model animals such as macaques, we rely …

Pupil size is sensitive to low-level stimulus features, independent of arousal-related modulation

JH Kim, C Yin, EP Merriam, ZN Roth - Eneuro, 2023 - eneuro.org
Similar to a camera aperture, pupil size adjusts to the surrounding luminance. Unlike a
camera, pupil size is additionally modulated both by stimulus properties and by cognitive …
