Investigating Phonological Representations: A Modeling Agenda
نویسنده
چکیده
This paperoutlines a bottom-up researchapproach to studying lexical representation, emphasizing the development of infant phonological perception as a source of data that can illuminate the nature of phonological representations. It is proposed that neural network formalisms can provide a useful framework for thinking about these issues. We identify a key set of empirical results, understanding of which would yield considerable insight; this defines a modeling agenda for investigation of phonological representations. We report preliminary simulations that explore this agenda, exemplifying how network modeling techniques can contribute to understanding of these phenomena.

Outstanding questions about phonological processing in dyslexia.
It is widely accepted that developmental dyslexia results from some sort of phonological deficit. Yet, it can be argued that phonological representations and their processing have been insufficiently tested in dyslexia research. Firstly, claims about how tasks tap into certain kinds of representations or processes are best appreciated in the light of an explicit information-processing model. He...
متن کاملAligning manifolds to model the earliest phonological abstraction in infant-caretaker vocal imitation
We argue that infants perform an abstraction over their auditory representations of the vowels of individual speakers, by mapping them to a mediating space of speaker-independent representations, guided by vocal imitative interaction with their caretakers, as a first step in the phonological acquisition process. Furthermore, we proffer a methodology for modeling this abstraction which involves ...
متن کاملModeling the control of phonological encoding in bilingual speakers
Phonological encoding is the process by which speakers retrieve phonemic segments for morphemes from memory and use the segments to assemble phonological representations of words to be spoken. When conversing in one language, bilingual speakers have to resist the temptation of encoding word forms using the phonological rules and representations of the other language. We argue that the activatio...
متن کامل"What you encode is not necessarily what you store": evidence for sparse feature representations from mismatch negativity.
The present study examines whether vowels embedded in complex stimuli may possess underspecified representations in the mental lexicon. The second goal was to assess the possible interference of the lexical status of stimuli under study. Minimal pairs of German nouns differing only in the stressed vowels [e], [ø], and [o], and derived pseudowords, were used to measure the Mismatch Negativity (M...
متن کاملAre phonological representations of printed and spoken language isomorphic? Evidence from the restrictions on unattested onsets.
Are the phonological representations of printed and spoken words isomorphic? This question is addressed by investigating the restrictions on onsets. Cross-linguistic research suggests that onsets of rising sonority are preferred to sonority plateaus, which, in turn, are preferred to sonority falls (e.g., bnif [symbol: see text] bdif [symbol: see text] lbif). Of interest is whether these grammat...
