This paper develops an fMRI method to measure contrast sensitivity across the visual field without requiring precise fixation, showing reliable patterns and tolerance to eye movement.

This study simulates visual deficits in healthy adults to determine if incomplete letter recognition issues in dementia patients are due to cortical or optical factors, finding cortical factors are more significant.

This study investigates foveal crowding in albinism, finding elevated crowding with nystagmus-related spatial anisotropy and lack of featural selectivity, suggesting both retinal motion and sensory deficits.

This study examines the development of visual acuity and crowding in children, finding that foveal crowding develops more slowly than acuity and shows similar selectivity to peripheral crowding.

This study shows that older adults maintain the ability to use prior knowledge for visual perception despite age-related sensory decline.

This study finds that older adults report fewer complex visual hallucinations than younger adults in an experimental setting, suggesting reduced hallucination proneness with age.

This paper shows that temporal confounds in fMRI studies of perceptual learning can create false signals of neural reorganisation, and suggests ways to mitigate these issues.

The paper examines hierarchical cortical plasticity in congenital sight impairment by comparing rod-only and typically developed visual systems, finding stability in early stages and compensatory reorganization in higher-order cortex.

The paper shows that face-selective brain regions share spatial sampling patterns with early visual cortex, supporting a hierarchical model of visuospatial organization in face recognition.

This study shows that perceptual reorganisation driven by prior knowledge develops late in childhood, as demonstrated by children's inability to recognize degraded images compared to adults and neural networks.

The paper examines brain connectivity delays during movie watching, finding sensory regions have the longest delays and reveal new spatial organisation patterns.

This study compares flicker and Ganzfeld techniques to determine if they share a common mechanism for inducing visual hallucinations, finding similar patterns in frequency and complexity.

This study investigates whether elevated foveal crowding in nystagmus is caused by eye movements or sensory deficits, finding that crowding is stronger with horizontal flankers, consistent with eye movement interference.

The paper introduces a dual-decisions method to infer confidence without explicit valuation, showing human confidence levels are discrete rather than continuous.

This study investigates age-related changes in population receptive field (pRF) properties in children and adults, finding no significant differences in pRF size, shape, or cortical magnification, suggesting visual perception improvements may stem from more efficient information use rather than neural tuning changes.
