Reports published in Vision Research during the late years of the 20th century described
surprising effects of long-term sensitivity improvement with some basic visual tasks as a …

Visual coding is a highly dynamic process and continuously adapting to the current viewing
context. The perceptual changes that result from adaptation to recently viewed stimuli …

Perception is our key to the world. It plays at least three different roles in our lives. It justifies
beliefs and provides us with knowledge of our environment. It brings about conscious mental …

A motion sequence may be represented as a single pattern in x–y–t space; a velocity of
motion corresponds to a three-dimensional orientation in this space. Motion sinformation …

A letter in the peripheral visual field is much harder to identify in the presence of nearby
letters. This is “crowding.” Both crowding and ordinary masking are special cases of …

We propose a model of how humans sense the velocity of moving images. The model
exploits constraints provided by human psychophysics, notably that motion-sensing …

Gordon Lynn Walls, a comparative anatomist, observed,“If asked what aspect of vision
means the most to them, a watchmaker may answer 'acuity,'a night flier 'sensitivity,'and an …

Seeking to understand how people recognize objects, we have examined how they identify
letters. We expected this 26-way classification of familiar forms to challenge the popular …

This study is the first to report the benefits of spatial covert attention on contrast sensitivity in
a wide range of spatial frequencies when a target alone was presented in the absence of a …

The spatial and temporal frequency selectivity of 148 neurones in the striate cortex, V1, and
of 122 neurones in the second visual cortical area, V2, of the macaque monkey were studied …
