But how should that complexity of perceptual content be explained or analyzed? I argue that perceptual representations normally have a double or two level nested structure of content, so as to adequately incorporate information both about contextual aspects Y(X) of an object X, and about the object X itself. On this double content (DC) view, perceptual processing starts with aspectual data Yprime(Xprime) as a higher level of content, which data does not itself provide lower level X-related content, but only an aspectually encoded form of such data. Hence the relevant perceptual data Yprime(Xprime) must be ’de-contextualized’ or decoded to arrive at the X-related content Xprime, resulting in a double content structure for perceptual data, that persists in higher-order conscious perceptual content. Some implications and applications of this DC view are also discussed.", pages = "225-243(19)", url = "http://www.ingentaconnect.com/content/klu/synt/2005/00000146/00000003/00006209" doi = "doi:10.1007/s11229-004-6209-3" }
