Active eye modeling: a tool for estimating retinal image quality across the visual field in everyday life

This paper introduces active eye modeling to estimate retinal image quality across the visual field during everyday activities, finding that near work under dim lighting increases peripheral blur.

Motor "laziness" constrains fixation selection in real-world tasks

The paper investigates fixation selection in real-world tasks and finds that motor 'laziness' drives return saccades and center biases, contradicting lab-based principles like inhibition-of-return.

Perceptual learning improves discrimination while distorting appearance

The paper shows that perceptual learning improves discrimination accuracy but distorts appearance estimates, suggesting learning enhances category distinctions.

A unified model of the task-evoked pupil response

This paper challenges the linear model of task-evoked pupil response and proposes an alternative model based on shared neural inputs driving saccades and pupil size, showing better alignment with behavioral and physiological predictions.

Task-related hemodynamic responses in human early visual cortex are modulated by task difficulty and behavioral performance

Heading Perception Depends on Time-Varying Evolution of Optic Flow

This paper tests the hypothesis that heading perception during rotation relies on instantaneous optic flow by introducing a novel stimulus and showing that time-varying optic flow is necessary for accurate heading judgments.

Uncharacteristic task-evoked pupillary responses implicate atypical locus coeruleus activity in autism

This study finds that individuals with ASD show atypical pupillary responses to distractor stimuli, suggesting altered locus coeruleus activity during attentional tasks.
