Results support the argument that anaphoric relations are constrained by more than one module of grammar. (12 references) (Author/CK)

Presents a framework for studying the effects of the Maturation Hypothesis on the problem of language learning, parametrically conceived, and offers a method for finding all existing maturational solutions for any parametric hypothesis space and any learning algorithm that differs from Gibson and Wexler's Triggering Learning Algorithm.

Evaluates two developmental models incorporating innovations in prosodic theory using the phonological forms of one child's vocabulary documented for the first nine months of language production. Results indicate the relevance of the prosodic hierarchy in the early grammar as well as considerable early knowledge of prosodic structure below the…

Presents the results of an investigation into the acquisition of syllable structure and stress by a preschool Dutch child. Shows how the structure of the child's output approaches the adult models in stages and discusses a phenomenon called "mutation," in which all continuants are consistently replaced with "n-" in onsets.
