A unified model of the task-evoked pupil response
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 …

Predicting visual search task success from eye gaze data as a basis for user-adaptive information visualization systems
Information visualizations are an efficient means to support the users in understanding large
amounts of complex, interconnected data; user comprehension, however, depends on …

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
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
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
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
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
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
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 …
