Representações dinâmicas e distribuídas: indícios do português brasileiro adulto e infantil

Abstract

This paper argues for dynamic distributed representations of phonological units and categories on the basis of analyses of the following sets of Brazilian Portuguese data: phonotactic biases in the adult lexicon, phonotactic biases in a child acquiring the liquid class, and covert phonological distinctions in a group of children diagnosed as phonologically impaired. Together, the three data sets support the emergence of abstract phonological categories from lexical phone frequencies as a result of the interaction between articulatory dynamics and phonotactics. The fact that most phonological information is neither punctual nor local has important implications for language acquisition, a number of which are discussed throughout the paper.
