Single-unit neurophysiology and human psychophysics have begun to reveal distinct neural
mechanisms for processing visual stimuli defined by differences in contrast or texture …

Visuo-perceptual processing in autism is characterized by intact or enhanced performance
on static spatial tasks and inferior performance on dynamic tasks, suggesting a deficit of …

Visual detection and discrimination thresholds are often measured using adaptive
staircases, and most studies use transformed (or weighted) up/down methods with fixed step …

In simple tests of preference, infants as young as newborns prefer faces and face-like stimuli
over distractors. Little is known, however, about the development of attention to faces in …

Visual textures are a class of stimuli with properties that make them well suited for
addressing general questions about visual function at the levels of behavior and neural …

Second-order textures—patterns that cannot be detected by mechanisms sensitive only to
luminance changes—are ubiquitous in visual scenes, but the neuronal mechanisms …

What is visual texture, and how might a study of the visual perception of texture help us to
better understand human vision? In this chapter we will attempt to give the reader a feel for …

The apparent contrast of a central stimulus is affected by the presence of surrounding
stimuli. For some stimulus conditions, the apparent contrast is suppressed and for other …

Cuing covert spatial attention can increase spatial resolution. Here we pinpointed the
specific locus of this effect using texture segmentation. At the level of visual cortex, texture …

In natural vision, the central nervous system actively selects information for detailed
processing through mechanisms of visual attention. It is widely held that simple stimulus …
