We investigated whether contour-shape processing mechanisms are selective for color
direction using the shape-frequency and shape-amplitude after-effects, or SFAE and SAAE …

We investigated the first-order inputs to contour-shape mechanisms using the shape-
frequency after-effect (SFAE), in which adaptation to a sinusoidally modulated contour …

Previous research has shown that the mechanisms that process curved contours are
selective for low-level attributes such as luminance contrast polarity and luminance spatial …

Contour-shape coding is color selective (Gheorghiu & Kingdom, 2007a) and surround
textures inhibit the processing of contour shapes (Gheorghiu & Kingdom, 2011; Kingdom & …

The shape-frequency and shape-amplitude after-effects, or SFAE and SAAE, are
phenomena in which adaptation to a sinusoidal-shaped contour results in a shift in …

We investigated the binocular properties of curvature-encoding mechanisms using the
shape-frequency and shape-amplitude after-effects (or SFAE and SAAE). The SFAE and …

The shape-frequency and shape-amplitude after-effects, or SFAE and SAAE, refer
respectively to the shifts observed in the perceived shape-frequency and shape-amplitude of …

Radial frequency (RF) contours can be used to represent the boundaries of natural objects,
making them a useful stimulus with which to study shape processing. The current study used …

In the present study we investigated the detectability of three-dimensional (3D) cocircular
contours defined by binocular disparity and established the influence of a number of …

The visual system integrates discrete but aligned local stimuli to form percept of global
contours. Previous experiments using “snake” contours showed that contour integration was …
