perceptual codes

Show Summary Details

Quick Reference

In semiotic discourse, a fundamental interpretive framework within which human beings construct sensory experience. Some semioticians regard sensory perception as a code (see alsovisual semiotics). Various arguments are encountered, in particular: that interpretation cannot be separated from perception; that human perceptual apparatus differs from that of other organisms and so presumably different species inhabit different perceptual realities; and/or that even within the human species, that there are sociocultural, subcultural, and environmental differences in perception. Such perceptual codes must thus be learnt (even if, as the gestalt psychologists demonstrated, some processes of perceptual inference seem to be universal). As a semiotic code, perception involves representation. Unlike most codes, the notion of a perceptual code does not assume intentional communication (there need be no sender).
