Abstract

A unified connectionist model of the perceptual magnet effect (the perceptual warping of vowels) is proposed, and relies on the concept of population coding in neural maps. Unlike what has been often stated, we claim that the imprecision of the classical ``sum of vectors'' coding/decoding scheme is not a drawback and can account for psychological observations. Furthermore, we show that coupling these neural maps allows the formation of vowel systems, which are shared symbolic systems, from initially continuous and uniform perception and production. This has important consequences for existing theories of phonetics.

Keywords: phonetics, self-organization, origins of language, population code, magnet effect, categorical perception
