Abstract

Traditional phonological analysis tools (rewrite-rules, templates, OT,
etc.) are all useful in describing particular aspects of child phonology, but none of them, I claim, can tell the whole story of phonological development insightfully, largely because of the high degree of lexical variation that is often present in child speech. I present some typical (Ferguson & Farwell, 1975) and atypical data (Schmidt, unpublished) that support these claims. I and my students Brent Nicholas and Ellen Schmidt offer a new exemplar-based attractor model, building on Vihman & Croft (2007) with Nicholas’ visualization of the relationships between adult and child forms.

This model combines strengths of previous attempts to understand phonological development and provides a major improvement in psycholinguistic plausibility. It incorporates phonetic/phonological information, frequency information, the notion that doing/thinking actually changes the brain and the phonological system, and the importance of what is salient/relevant to the child. Our goal is to provide a representation of associations between elements in the child’s phonology and the impact they exert upon one another which could be modeled computationally.
