        abstract = {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.
