Presents an outline for a theory of syntax acquisition, surveys other approaches to language acquisition, and addresses the following methodological issues: (1) the relevance of linguistic theory to the model; (2) how the model is tested; and (3) the domain of the theory. (Author/AM)

Ninety children between the ages of three and six described objects which differed on three simultaneous dimensions, using adjective combinations appropriate to the dimensions. Each child performed an imitation, comprehension, and production task. (Author/CFM)

The present study is an attempt to apply a paradigm to the shift of verbal behavior before and after the age of seven in order to see if linguistic contexts affect verbal behavior differentially before seven or after seven. (Author/CFM)

Sentences were constructed in which the terms "before" and "after" were embedded in logically constrained and logically reversible sequences. The preschool children in the study found the constrained sentences easier to comprehend. (Author/CFM)

This article discusses a study by Segalowitz and Galang that reports results showing better mastery of patient-focus sentences than agent-focus sentences for Tagalog children. (CFM)

This article discusses the way in which children use tense to distinguish between different realities in games of pretend. (CFM)

Inferences about linguistic competence in children are typically based on spontaneous speech. Children's use of complex object and adverbial noun phrase is seen as a reflection of pragmatic factors. Similar adult patterns indicate children's lack of subject clauses may be due to the nature of spontaneous speech. (CHK)

Acquisition of the words "this" and "that" was tested by a comprehension and a production task with children aged 4 and 7. It was confirmed that children would learn the spatial contrast between the words and apply it from the speakers viewpoint; non-egocentrism was not deemed necessary for correct use. (CHK)

Describes the transition from single to multiple word utterances in one child. The development illustrates the initial dissociation and later coordination of the temporal chaining of elements and meaning relatedness between elements and also the importance of repetition for the change from single-word utterances to meaning-related, multiword…

Input language addressed to language-learning children was analyzed to assess the quality of the semantic-syntactic correspondence posited by the semantic bootstrapping hypothesis. This correspondence was strong--objects were labeled with nouns, actions with verbs, attributes with adjectives--and may serve to make children's construction of…

In this longitudinal study, changes in parental labelling and infants' categorization skills were examined as potential predictors of vocabulary acquisition, the age of the naming explosion, and the acquisition of subordinate labels. Findings suggest that the influence of each factor varies as a function of the stage and aspect of lexical…

The claim that multiple-birth children use "twin language" was investigated by describing and comparing the phonological characteristics of the speech of 19 sets of multiple birth children (aged 2-4) and by measuring multiple-birth children's understanding of their twins' or triplets' context-free speech. Results indicated that multiple…

A blind child and her sighted twin sister were recorded at home once a month from 2;5 to 3;5, and their repetitions and routines were analyzed with respect to three dimensions. Results showed that the blind twin used routines and modified imitations and repetitions more frequently, and her use of modified repetitions increased during the study.…

Data from 34 children suggest that a range of Italian grammatical morphemes reach the level of mastery by age 3;6-4;0. In the period between 2;6 and 3;0, as use and comprehension of morphemes are being consolidated, homonymy and informativeness seem not to play a role, though number continues to exert an influence. Some form classes of Italian are…

This study tested the hypothesis that children as young as two years use what adults tell them about meaning relations when making inferences about new words. Subjects (n=18) learned two new terms, with instructions to treat one term as superordinate to the other or replace one with the other, and with no instructions. Children used both kinds of…
