In Reply.  —We use the terms identification and localization with their usual connotation in the classic approach to the "what and where" problem. This approach distinguishes basically two visual systems for orienting and identifying1 and two cortical neural networks for the parallel processing of visual information related to object qualities (shape, color, size, and so on) and to object location in the extracorporeal space.2 Both object quality and location are properties that can be memorized and recognized. This recognition is obviously a perceptive process that presupposes some kind of "awareness," some conscious elaboration of the sensory experience. If we had chosen to restrict our investigation to "gnostic" functions, the comments of Dr Schady would have been entirely relevant, and his suggestion to improve the study of "topognostic" capacity are indeed most interesting. Our study, however, dealt with quite another facet of the localization function.
