This paper introduces a dual-kernel deconvolution model to estimate latent attentional responses from pupil signals, revealing faster attentional dynamics previously obscured by the slow pupillary response.

The paper examines how prestimulus pupil size relates to detection performance in visual and auditory tasks, finding it improves visual detection but not auditory detection, suggesting different mechanisms in each domain.

The paper shows pupil constriction triggers retinal and visual cortex activity independent of visual stimuli, revealing a new mechanism in visual processing.

This study replicates previous findings that pupil size changes during exploration and exploitation but finds no effect of exploration on visual sensitivity.

This study shows that covert attention can be directed within afterimages, as evidenced by pupil size tracking the brightness of attended stimuli during and after their perceptual fading.

The paper investigates whether pupil size reflects moment-to-moment imagery vividness or individual differences in imagery, finding that pupil size correlates with moment-to-moment fluctuations but not with individual differences.

The paper shows that larger pre-stimulus pupil size improves near-threshold detection performance regardless of stimulus color, eccentricity, or retinal adaptation state.

The paper shows that saccade selection is driven by the effort (cost) associated with each saccade, with less costly directions being preferred even in natural scenes and under increased cognitive demand.

The paper examines how pre-stimulus pupil size and EEG power in alpha, beta, and theta bands influence near-threshold detection sensitivity and decision criteria.

This study challenges the traditional view of pupillary changes during respiration, showing pupils are smallest at inhalation onset and largest during exhalation across multiple conditions.

The paper investigates how pupil size fluctuations affect retinal responses to visual stimuli and finds that pupil size changes do not impact early retinal responses but the direction of change does.

This study investigates the relationship between resting-state pupil size and cognitive abilities, finding no significant associations after controlling for confounding variables.

The paper shows that pupil dilation occurs with increased attentional breadth, correlating with improved performance in peripheral vision tasks.

This study investigates whether continuous visual working memory representations require more mental effort than categorical ones by measuring pupil dilation during a delayed estimation task.

This study investigates how memory load and retention interval affect categorical bias in visual working memory, finding that bias increases with load and is stronger at longer intervals.

The paper tests adaptive gain theory by linking pupil size to exploration and exploitation behaviors in a visual search task using eye movements.

The paper investigates whether working-memory content guides attention during real-life search, finding that gaze is strongly directed towards memory-matching stimuli from the start of the search.

The paper tests whether multiple or single items in visual working memory guide attention during visual search using behavioral and computational models.

This study investigates how pupil size and peripheral brightness affect visual detection and discrimination performance, finding that small pupils improve discrimination of fine stimuli while large pupils enhance detection of faint stimuli.

This study shows that pupil size changes reflect visual working memory content through attention shifts during encoding and briefly after, suggesting a transient active memory state.

The paper replicates two studies on visual working memory and attentional capture, finding reliable results that suggest the need to determine boundary conditions for memory-driven capture.

The paper replicates findings that semantic brightness of words modulates pupil size, supporting the idea that language processing involves visual brain areas.
