Pictorial representation is a subject of interest to both cognitive science and aesthetics. Standard theories of depiction often draw on vision science, and vision science must give an account of picture perception. I offer a critical overview of standard theories of depiction and argue that none of them is adequate. I then describe ways in which new theories of perception blend elements of representationalism with an emphasis on attention and motor control. Such theories, in effect, limit the reliance on mental (...) representation in perceptual tasks. This work provides the basis for a theory of depiction in which pictorial representation is explained in terms of both mental representations and perceptual strategies. I argue that, in the case, the mental representations are most plausibly individuated by the functional and conceptual roles, rather than by causal links to the external world. (shrink)

A novel account of semantic information is proposed. The gist is that structural correspondence, analysed in terms of similarity, underlies an important kind of semantic information. In contrast to extant accounts of semantic information, it does not rely on correlation, covariation, causation, natural laws, or logical inference. Instead, it relies on structural similarity, defined in terms of correspondence between classifications of tokens into types. This account elucidates many existing uses of the notion of information, for example, in the context of (...) scientific models and structural representations in cognitive science. It is poised to open a new research program concerned with various kinds of semantic information, its functions, and its measurement. (shrink)
