We compare the predictions of two different accounts of first language acquisition by investigating the relative contributions of abstract syntax and input frequency to the elicited production of main and embedded questions by 36 monolingual English-speaking toddlers aged 3;00 to 5;11. In particular, we investigate whether children's accuracy…

Two recent proposals link the use of nonagreeing "don't" to the Root Infinitive (RI) Stage. Guasti & Rizzi (2002) argue for a misset parameter involving how agreement is spelled out. Schütze (2010) proposes that Infl is underspecified in child language and that "do" surfaces to support the contracted clitic/affix…

This paper examines two issues concerning nonagreeing "don't" in child English, e.g., "He don't fit". (1) Do children know that "don't" consists of auxiliary "do" plus sentential negation, or do they misanalyze it simply as negation? I argue that the former claim yields both empirical (distributional) and conceptual advantages, while the latter…

The role of homophony in language change and in child morphological acquisition has often been made recourse to. Regarding the former it has been proposed that the threat of homophony can prevent a sound change from going to completion. With respect to the latter, it has been vaguely and contradictorily claimed that homophonous morphological…

There are problems in interpreting the naming behavior of children. Children may misname a word because the word is absent from their vocabulary, because it is not yet firmly established, or because of a word retrieval or lexical assessing problem. Preliminary results are reported of an experimental technique designed to account for these…

The count/mass disinction is often considered to be a semantic one because it distinguishes those nouns that refer to countable things from those that refer to non-countable things. However, exceptions indicate that semantic properties alone are not sufficient to determine noun sub-categorization. Therefore, such sub-categorization must be defined…

This study documents the emerging ability of children to use demonstrative expressions and definite and indefinite articles in order to establish a clear reference for the hearer in a natural discourse situation. The analysis is based primarily on transcripts of twins recorded over a period of nine months when they were 33 to 42 months old.…

Reports on a study which sought to compare syntax acquisition in French by francophone and non-francophone children, in order to establish the order in which French grammatical elements are acquired, and in order to create a French version of the Bilingual Syntax Measure. (AM)

Selected spontaneous errors of word choice made between the ages of two and five by two children whose language development had been followed longitudinally were analyzed for clues to semantic developmnet. (JMB)

The purpose of the paper was to map the language development of children at infant school and examine spontaneous corrections made by the children of their speech. (Author/NCR)

A cross-sectional and a longitudinal study of two-year-old children was performed to investigate the developmental relationship between understanding differences in spatial point of view and correct comprehension and production of I/you pronouns. Results suggest that understanding spatial points of view is a cognitive prerequisite to understanding…

Discusses results of study that attempted to determine whether subject-auxiliary inversion occurs in yes-no questions before wh-questions and whether noninversion errors are characteristic feature of acquisition of wh-questions. Findings do not support previous claims that inversion is acquired in yes-no questions before wh-questions. Rather,…

This is a quarterly report of a project involving the analysis of the language of four Puerto Rican children living in the Boston area who are learning Spanish as a first language. The children, all male, ranged in age from 17 months to 37 months during the period of study. All had some contact with English. The data were transcriptions of…

Reports on an experiment to check whether the use of articles by Italian preschool children corresponds to that of their English counterparts and on a second experiment to investigate the probability that subjects might produce the correct response distribution by following a rule based on the speaker's familiarity with the referent, not the…

Part one of this study discussed the characteristics of errors involving single fricative consonants made by English children learning their first language. Here, the second part discusses the distinctive features of the single fricatives most commonly mispronounced, as well as the characteristics of errors with clustered fricatives. (34…
