This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

This study analyses variation sets in a sample of child-directed speech (CDS) in Turkish in terms of their structure and effect on child speech. The term "variation set" was first introduced to describe the sequences of repetitions, in which the intention behind expressions stays the same throughout the whole conversation while the form…

The present study examined the relation between language and social ability in a sample of 268 preschoolers aged 18-35 months. Expressive language was assessed with the Italian adaptation of the Language Development Survey (LDS), and Social Competence was assessed with the Questionnaire on Peer Interactions in the Kindergarten (QPI). Results…

This article addresses a child language stage that has figured prominently in the current debate on children's early linguistic competence: the Optional Infinitive (OI) stage, a relatively extended period during which children freely alternate between finite and nonfinite structures in contexts where adults only use finite forms. The study…

In the 1980s, researchers in child language devised several new experimental techniques to assess children's emerging linguistic competence. Innovations in methodology were needed to bridge the apparent gap between the expectation of rapid language acquisition, based on linguistic theory, and the protracted acquisition that was being witnessed…

This dissertation studies the acquisition of verb argument structure in the basilectal subvariety of Jakarta Indonesian (henceforth, bJI). There are two characteristics of bJI that potentially affect the acquisition of verb argument structure. First, bJI sentences can surface not only in the full frame but also in truncated frames. Second, the…

This article investigates the acquisition of the focus particle "auch" "also" by German-learning children. We report data from spontaneous and elicited production of utterances with the focus particle "auch" by 1- to 4-year-olds complementing earlier findings of a delayed production of the unaccented "auch" compared to the accented one. But in…

Outlines work suggesting that research into children's learning of linguistic structure has progressed little in the last decade or so, identifying attitudinal and methodological difficulties, and suggesting a comparative method for identifying learning strategies as developed by individual children.

Three experiments on the comprehension and acquisition of temporal terms are described. Methodological innovations were applied to control for possible methodological effects on children's performance. Each experiment involved 24 children aged 3 to 5. In the first experiment, subjects manipulated toys in response to instructions containing the…

An experiment was undertaken with young children to look at the relative contribution of discourse constraints, subject anaphors, and the semantics of verbs to the integration of an utterance into its discourse representation. Children aged 5, 7, and 10 years heard a series of short stories, each consisting of three sentences and an incomplete…

The proposal that young children's communicative intentions stem from prelinguistic cognitive abilities is examined in detail. The most developed available formulation of this proposal, that provided by Brown (1973), is evaluated, and the evidence in support of it is found to be insufficient. Three crucial problems, which must be solved before an…

Discusses the use of linguistic resources the child has already acquired when he comes to school in helping him learn to read and communicate effectively. (Author/RB)

A study was conducted in which a series of stories was used to teach six four- to five-year-olds to identify objects as "nouns," attributes of objects as "adjectives," and actions as "verbs." All the children appeared to have well-formed semantic fields for the three form classes. (Author/RM)
