Independent mechanisms for processing local contour features and global shape.
The visual system can extract the global shape of an object from highly variable local
contour features. We propose that there are separate systems for processing local and …

[HTML][HTML] Lateral inhibition between banks of orientation selective channels predicts shape context effects: a tilt-illusion field
The perceived shapes of almost circular paths are modified by concentrically placed context
paths. These induced changes have previously been attributed to curvature masking. This …

[HTML][HTML] Global processing of random-phase radial frequency patterns but not modulated lines
Previously, researchers have used circular contours with sinusoidal deformations of the
radius (radial frequency [RF] patterns) to investigate the underlying processing involved in …

[HTML][HTML] Visual search reveals a critical component to shape
Abstract Objects are often identified by the shape of their contours. In this study, visual
search tasks were used to reveal a visual dimension critical to the analysis of the shape of a …

[HTML][HTML] Convergent evidence for global processing of shape
There is an ongoing debate over whether there is convincing evidence in support of global
contour integration in shape discrimination tasks, particularly when using radial frequency …

[HTML][HTML] Integration of shape information occurs around closed contours but not across them
Scenery and complex objects can be reduced to a combination of shapes, so it is pertinent
to examine if the integration of information found occurring around simple contours also …

Separate banks of information channels encode size and aspect ratio
Size and aspect ratio are ecologically important visual attributes. Relative size confers
depth, and aspect ratio is a size-invariant cue to object identity. The mechanisms of their …

[HTML][HTML] Rejecting probability summation for radial frequency patterns, not so Quick!
Radial frequency (RF) patterns are used to assess how the visual system processes shape.
They are thought to be detected globally. This is supported by studies that have found …

[HTML][HTML] The effect of spatiotemporal displacement on the integration of shape information
Within a natural scene it is not uncommon for an object's shape to be revealed over time. We
investigated whether the same integration of shape information that happens around a fully …
