Reports a case study of a British 2-year old that shows a stage in syntactic development without a subject agreement protection but with a tense phrase. A sharp contrast in use of verb forms suggests that the child had left the Optional Infinitive stage and entered a transitional stage, where the major development is that the status of the bare…

Two studies investigated developmental changes, and inter-linguistic and inter-individual variations, in the expansion and composition of young French children's early lexicons. Results indicated that lexical productivity strongly increased with age, whereas lexical diversity showed little developmental progression. Inter-individual variability in…

Twenty-two Spanish-speaking children ages 3 to 6 years participated in an elicited production study designed to test whether children's ability to produce subjunctive relative clauses related to their ability to pass a false-belief task. Results indicated a strong correlation between children's ability to use the subjunctive mood in relative…

Compared expressive vocabulary data from a systematic diary study of one child's early language development with data from longitudinal administration of the MacArthur Communicative Development Inventories spoken vocabulary checklist (CDI). The CDI underestimated the number of words in the diary study. Logistic curves were the best-fitting model…

Explores the acquisition process of relative clauses in Japanese and Korean. Examines the issue of whether Korean "kes" and Japanese "no" found in Korean and Japanese relative clauses are each a complementizer or a head noun.(Author/VWL)

Examines controversial interactions between children, a group generally overlooked in second-language acquisition research. Specifically, the research focuses on (1) whether children can negotiate for meaning, (2) what strategies they use, and (3) whether there are differences between the ways adults and primary school children negotiate for…

Assessed long-term predictive validity of the MacArthur Communicative Development Inventories: Words and Sentences (CDI:WS) for children's expressive and receptive vocabulary development. Sixty-one New Zealand children were assessed with a New Zealand version of the CDI, and with the Expressive Vocabulary Test and Peabody Picture Vocabulary…

Explores two Mandarin-speaking children's ability to refer to the past in mother-child conversation. The approach encompasses morphosyntactic, semantic, and discourse-pragmatic perspectives. Results show that the children tend to refer to immediate past spontaneously, but rely heavily on elicitation when referring to earlier past. (Author/VWL)

Investigates the cross-linguistic patterns of the overgeneralization of the intransitive/transitive alternations found in children's speech and provides new evidence from findings based on the acquisition of French. The morphosyntatic characterization of such phenomena in English and Hebrew child language is followed by a description of the…

Evaluates the claim of uniform size and shape restrictions in prosodic development using a cross-sectional database of English-speaking children's multisyllabic word productions. Suggests children's increasing faithfulness to unstressed syllables can be explained by different constraint rankings that relate to edge alignment, syllable structure,…

Explores the possibility that particular properties of how number words are used within sentences inform children of the semantic class to which they belong. Analysis of transcripts of the spontaneous speech of three children and their parents suggests that the relevant cues are available as input in parents' speech to children and that children…

Compared production of gestures, signs, and words by a child simultaneously acquiring sign language and speech to that of a group of children exposed only to speech. Found that exposure to sign language influences the extent to which the manual modality of expression is used for communicative purposes but does not alter the rate or course of…

Various commentaries are included in response to an article on filler syllables and their status in emerging grammar. (Author/VWL)

Investigates acquisition of the rhyme using cross-sectional and longitudinal data from 14 English-speaking children between 1- and 2-years of age. Focuses on four questions pertaining to rhyme development that are motivated from current theories of prosodic acquisition. (Author/VWL)

Studied the case of bilingual acquisition across two modalities to examine diverging hypotheses about the types of knowledge underlying early bilingualism. Three children acquiring Langues des Signes Quebecoise and French, and three children acquiring French and English were videotaped over a year while novel and familiar speakers of each child's…
