How does attention optimize our visual system for the task at hand? Two mechanisms have
been proposed for how attention improves signal processing: gain and tuning. To …

We introduce a novel framework for estimating visual sensitivity using a continuous target-
tracking task in concert with a dynamic internal model of human visual performance …

Damage to the primary visual cortex typically causes cortical blindness (CB) in the hemifield
contralateral to the damaged hemisphere. Recent evidence indicates that visual training can …

The job of any sensory system is to create objects in the world out of the incoming proximal
stimulus energy. The energy is neutral; it does not specify the objects itself. Thus, sensory …

To assess influences of fixational drift eye movements on motion detection, lower thresholds
for motion and drift amplitudes were measured in normal subjects. The threshold was higher …

Global motion perception matures during childhood and involves the detection of local
directional signals that are integrated across space. We examine the maturation of local …

Purpose.: Sensitivity to moving structure decreases with age and slow speeds may be
selectively impaired. This loss could be caused by elevated internal noise in the responses …

The human visual system has specialised mechanisms for encoding mirror-symmetry and
for detecting symmetric motion-directions for objects that loom or recede from the observers …

purpose. Primary open angle glaucoma (POAG) is a leading cause of irreversible adult
blindness and is characterized by progressive optic neuropathy and constriction of the visual …

We compared thresholds for discriminating changes in speed by 5-year-olds and adults for
two reference speeds: 1.5 and 6° s− 1. Both adults and 5-year-olds were more sensitive to …
