Children achieve better long-term language outcomes than adults. However, it remains unclear whether children actually learn language "more quickly" than adults during real-time exposure to input--indicative of true superior language learning abilities--or whether this advantage stems from other factors. To examine this issue, we…

Ambridge argues that the existence of exemplar models for individual phenomena (words, inflection rules, etc.) suggests the feasibility of a unified, exemplars-everywhere model that eschews abstraction. The argument would be strengthened by a description of such a model. However, none is provided. I show that any attempt to do so would immediately…

We present a neural network model of learning and processing the English past tense that is based on the notion that experience-dependent cortical development is a core aspect of cognitive development. During learning the model adds and removes units and connections to develop a task-specific final architecture. The model provides an integrated…

Generic sentences (e.g., "Birds lay eggs") convey generalizations about entire categories and may thus be an important source of knowledge for children. However, these sentences cannot be identified by a simple rule, requiring instead the integration of multiple cues. The present studies focused on 3- to 5-year-olds' (N = 91) use of…

This paper investigated children's ability to use syntactic structures to infer semantic information. The particular syntax-semantics link examined was the one between transitivity (transitive/intransitive structures) and telicity (telic/atelic perspectives; that is, boundedness). Although transitivity is an important syntactic reflex of telicity,…

Current views on the acquisition of PRO can roughly be divided into two areas: lexical and syntactic accounts. We present data on one verb, "decide," that yields data that not only differs from the data for other similar verbs with the same children, but does not lend itself easily to either type of account. Data from a sentence elicitation task…

Previous research has reported instances in which some two-year-olds failed to overextend in comprehension what they overextended in use. Fremgen and Fay found no instance of overextension in comprehension in separate experiments. From this Fremgen and Fay conclude children never overextend in comprehension. This conclusion is re-evaluated here.…

A line of reasoning used in recent research on language acquisition assumes that a child acquiring the language has only two reliable sources of information available about the target grammar: a set of grammatical principles and the primary data of the language spoken around him. A third kind of evidence, negative evidence, would be helpful but is…

A model for adult language learning should integrate theories in language acquisition with theories about learnability and proposals about adult language structures. Two particular problems in language acquisition are examined: (1) establishing what counts as a formal relationship in a particular domain, and (2) retreating from overgeneralizations…
