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…

In 'Against Stored Abstractions,' Ambridge uses neural and computational evidence to make his case against abstract representations. He argues that storing only exemplars is more parsimonious -- why bother with abstraction when exemplar models with on-the-fly calculation can do everything abstracting models can and more -- and implies that his…

Ambridge argues that there is widespread agreement among child language researchers that learners store linguistic abstractions. In this commentary the authors first argue that this assumption is incorrect; anti-representationalist/exemplar views are pervasive in theories of child language. Next, the authors outline what has been learned from this…

We present data from an artificial language domain that suggest new contributions to the theory of syntactic triggers. Whether a learning algorithm is capable of matching the achievements of child learners depends in part on how much parametric ambiguity there is in the input. For practical reasons this cannot be established for the domain of all…

This article investigates the acquisition of object shift in Norwegian child language. We show that object shift is complex derivationally, distributionally, and referentially, and propose a new analysis in terms of IP-internal topicalization. The results of an elicited production study with 27 monolingual Norwegian-speaking children (ages…

First written in 1986, prior to the many findings concerning the optionality of finiteness and the root infinitive phenomenon, this article attempts to extend the parameter-setting model of grammatical development to the acquisition of inflectional morphology. I propose that the Stem Parameter, which states that a stem is/is not a well-formed word…

Recent work on the acquisition of number words has emphasized the importance of integrating linguistic and developmental perspectives [Musolino, J. (2004). The semantics and acquisition of number words: Integrating linguistic and developmental perspectives. "Cognition 93", 1-41; Papafragou, A., Musolino, J. (2003). Scalar implicatures: Scalar…

This dissertation investigates the acquisition of early verb inflection in child Slovenian from morphosyntactic and morphophonological perspectives. It centers on the phenomenon of root nonfinites, particularly the patterns of omission and substitution errors in verb inflection marking. It argues that every acquisition model needs to account…

Where do the two languages of the bilingual child interact? The literature has debated whether bilingual children have delays in the acquisition of direct objects. The variety of methods and languages involved have prevented clear conclusions. In a transitivity-based approach, null objects are a default structural possibility, present in all…

Outlines descriptive, theoretical, and methodological advances in child language research since the first volume of the "Journal of Child Language" was published. Papers in this volume build on earlier research, point the way to new research avenues, and open new lines of inquiry. (Contains 36 references.) (JP)

Presents examples of how children acquire language through the principles-and-parameters model, a highly modular system in which different theories interact so that only permissible sequences arise, and highlights research on Spanish syntax and semantics. (136 references) (CB)

Argues that the data used to claim that morphosyntactic development of Italian-speaking children are inconsistent with nativist, parameter-setting models of language development is irrelevant to the specific hypothesis being evaluated. (25 references) (JL)

Argues that to improve the parameter model as a theory of language acquisition it has to be constrained in several ways. Results on the acquisition of subject-verb agreement, verb placement, empty subjects, and negation in German child language are presented. (55 references) (JL)

A model of the child's learning of the past tense forms of English verbs is discussed. This connectionist model takes as input a present-tense verb and provides as output a past tense form. A new simulation is applied to 13 problems raised by critics of the model, presented as fundamental flaws in the conceptualizations underlying connectionism.…

This paper discusses the development of children's communicative abilities in relation to three models: the psycholinguistic model, which posits that grammatical competence is achieved through children's innate ability to abstract linguistic rules and apply them in creating sentences; the Bernstein hypothesis, which holds that not everyone…
