On representation of solids: A note

Current theories of representation of 3-D objects assume that they are geometrical facsimiles of represented objects and, therefore, imply that various aspects of the representations arc as concordant as are those of the objects themselves. Empirical data presented here question this as they show that subjects' choices of distinct views of objects are not mutually concordant. This being so, it seems unlikely that a facsimile representation of a solid yields a full description of the process of representation.
