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 …

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

Studies have shown that spatial aftereffects increase with eccentricity. Here, we demonstrate
that the shape-frequency and shape-amplitude aftereffects, which describe the perceived …

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 …

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 …

Prior studies using brief stimulus sequences revealed “opponent shape aftereffects”,
indicative of direct opponent coding of global shape attributes such as aspect ratio, skew …

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 …

Contextual influences on neurons in the primary visual cortex have largely been studied
using simple visual stimuli and their functional role is still poorly understood. Using a novel …

Radial Frequency (RF) patterns can be used to study the processing of familiar shapes, eg
triangles and squares. Opinion is divided over whether the mechanisms that detect these …
