There's a tremendous Web page that examines this statement in detail, with several enlightening demonstrations. It's from Dr. Matt Davis, a researcher at the Cognition and Brain Sciences Unit, Cmabridge Uinervtisy... oh, you know what I mean.
Well worth a few minutes. http://www.mrc-cbu.cam.ac.uk/~matt.davis/Cmabrigde/
