Dissociations of perception and action do not automatically imply independent visual processing streams

Abstract:
Abstract Since the publication of Milner and Goodale's perception-action model of visual processing, there has been a general tendency to attribute any dissociation in the performance of perceptual and action tasks to a difference in the abilities and limitations of the ventral and dorsal visual streams. However, behavioral dissociations do not necessarily imply different underlying neural systems. In particular, there is a class of illusions, brought about by distortions of the observer's egocentric reference frame, that can cause perception-action dissociations without requiring or implying the existence of separate visual processing streams.
