Within the last five years, there have been a number of exciting new advances in our
knowledge and understanding of amblyopia. This article reviews recent psychophysical …

Amblyopes show specific deficits in processing second-order spatial information (eg Wong,
Levi, & McGraw (2001). Is second-order spatial loss in amblyopia explained by the loss of …

To understand how different spatial frequencies contribute to the overall perceived contrast
of complex, broadband photographic images, we adapted the classification image …

A fundamental task of the visual system is to extract figure–ground boundaries between
images of objects, which in natural scenes are often defined not only by luminance …

Humans with amblyopia have a well-documented loss of sensitivity for first-order, or
luminance defined, visual information. Recent studies show that they also display a specific …

Vision must analyze the retinal image over both small and large areas to represent fine-
scale spatial details and extensive textures. The long-range neuronal convergence that this …

To represent the local orientation and energy of a 1-D image signal, many models of early
visual processing employ bandpass quadrature filters, formed by combining the original …

Binocular combination for first-order (luminance-defined) stimuli has been widely studied,
but we know rather little about this binocular process for spatial modulations of contrast …

When observers detect an oriented, broadband contrast increment on a background of 1/f
spatial noise, thresholds will be lowest for obliquely orientated stimuli and highest for …

This study characterises the spatiotemporal “window of visibility” for first-order motion
(luminance-modulated noise) and three varieties of second-order motion (contrast …
