BACKGROUND AND AIMS: Visual experience appears rich in detail despite the poor
performance of the vast majority of the visual field, as a result of the integration of coarse …

A polygon is regular if all its angles and sides are equal. We manipulated regularity along a
continuum by fixing the length of one side of a triangle and allowing the lengths of the …

A contrast-gain control (normalization) has been demonstrated by having observers
subjectively rate the perceived texture segregation of element-arrangement textures from …

We assessed whether the visual system's ability to discriminate subtle perturbations from
smoothness in curved shapes was based on 1st-order properties or 2nd-order properties …

The effects of background luminance, contrast, and background wavelength on the
perceived size of small line figures were studied at mesopic levels of light adaptation …

Purpose: Gurnsey and Browse (1987) showed that the textures comprising randomly rotated
Ls, embedded in a background of randomly rotated Xs are more easily detected than Xs …

Why do the equally spaced dots in figure 1 appear regularly spaced? The answer 'because
they are'is naive and ignores the existence of sensory noise, which is known to limit the …

The perception of object structure in the natural environment is remarkably stable under
large variation in image size and projection, especially given our insensitivity to spatial …

Abstract Recently, Burr and Ross (2008) reported a negative adaptation after-effect on the
perceived numerosity of dot displays. Based on these findings, they proposed that …

In three experiments a simple Euclidean transformation (reflection, translation, rotation) was
applied to collections of twelve dots in such a way that they contained equal lower-order …
