Global shape processing involves feature-selective and feature-agnostic coding mechanisms

Bell, Jason; Forsyth, Mimosa; Badcock, David Russell; Kingdom, Frederick A A

Description

Recent research and modeling proposes that a closed shape is accurately described by both the curvature and angular location of its parts relative to the shape center, implying that the shape is coded along with its overall orientation.We tested this proposition. Radial frequency (RF) patterns were employed as stimuli as they can represent a range of familiar closed shapes and are processed globally. We measured a RF amplitude aftereffect (RFAAE) as a function of the shape orientation...[Show more]
