%A Michael W Spratling %A Mark H Johnson %J Visual Cognition %T A feedback model of perceptual learning and categorisation %X Top-down, feedback, influences are known to have significant effects on visual information processing. Such influences are also likely to affect perceptual learning. This article employs a computational model of the cortical region interactions underlying visual perception to investigate possible influences of top-down information on learning. The results suggest that feedback could bias the way in which perceptual stimuli are categorised and could also facilitate the learning of sub-ordinate level representations suitable for object identification and perceptual expertise. %N 2 %K Perception; Learning; Neural Networks; Representation; vision %P 129-165 %V 13 %D 2006 %L cogprints4885
