In two sentence repetition experiments, we investigated whether four- and five-year-olds master distinct representations for intransitive verb classes by testing two syntactic analyses of unaccusatives (Burzio, 1986; Belletti, 1988). Under the assumption that, with unaccusatives, the partitive case of the postverbal argument is realized only on…

The present study compared the performance of twenty-seven French-speaking internationally adopted (IA) children from China to that of twenty-seven monolingual non-adopted French-speaking children (CTL) matched for age, gender, and socioeconomic status on a Clitic Elicitation task. The IA children omitted significantly more accusative object…

Two studies investigated syntactic productivity in three-year-old Mandarin speakers' use of verbs in the SVO and S"ba"OV constructions. In Study 1, children were taught novel verbs in one construction and assessed for their production in the other construction. Children produced verbs taught in the "ba" constructions in…

To understand how children develop adult argument structure, we must understand the nature of syntactic and semantic representations during development. The present studies compare the performance of children aged 2;6 on the two intransitive alternations in English: patient ("Daddy is cooking the food"/"The food is cooking")…

The objective of this work was to analyze morphosyntactic development in a wide sample of children with Down syndrome (DS) ("n" = 92) and children with typical development (TD) ("n" = 92) with a mental age (MA) of 20 to 29 months. Children were individually matched for gender and MA (Analysis 1) and for vocabulary size…

The aims of the study were to establish whether there is a correlation between the socioeconomic background of Afrikaans-speaking children and their performance on a dialect-neutral language test, and to ascertain whether the allowance the test currently makes for parental education level is sufficient. The Afrikaans version of the…

This longitudinal study examined the predictive validity of the MacArthur Communicative Developmental Inventories-Short Form (CDI-SF), a parent report questionnaire about children's language development (Fenson, Pethick, Renda, Cox, Dale & Reznick, 2000). Data were first gathered from parents on the CDI-SF vocabulary scores for…

We studied spontaneous speech noun-phrase production in eight French-speaking children with SLI (aged 5;0 to 5; 1) and controls matched on age (4;10 to 5;11) or MLU (aged 3;2 to 4;1). Results showed that children with SLI prefer simple DP structures to complex ones while producing more substitution and omission errors than controls. The three…

There are differences and similarities between Modern Standard Arabic (MSA) and spoken varieties of Arabic, in all language domains. To obtain preliminary insights into interactions between the acquisition of spoken and standard varieties of a language in a diglossic situation, we employed forced-choice grammaticality judgments to investigate…

Priming methodology was previously used to investigate children's ability to represent abstract syntactic forms. Existing evidence indicates that following exposure to a particular syntactic structure (such as the passive voice), English-speaking children increase their production of that structure with new lexical items. In the present work, we…

This paper investigates early productivity of morpheme use in Hungarian children aged between 2 ; 1 and 5 ; 3. Hungarian has a rich morphology which is the core marker of grammatical functions. A new method is introduced using the novel word paradigm in a sentence repetition task with masked inflections (i.e. a disguised elicited production task).…

The present study exposed five-year-olds (M=5 ; 2), seven-year-olds (M=7 ; 6) and adults (M=22 ; 4) to instances of a novel phrasal construction, then used a forced choice comprehension task to evaluate their learning of the construction. The abstractness of participants' acquired representations of the novel construction was evaluated by varying…

This study examines the word order phenomenon of optional scrambling in Ukrainian. It aims to test factors such as semantic features and object type that have been shown to affect scrambling in other languages. Forty-one children between 2 ; 7 and 6 ; 0, and twenty adult speakers participated in an elicited production experiment. The picture…

Previous research has found that children who are acquiring argument-drop languages such as Turkish and Chinese make use of syntactic frames to extend familiar verb meanings (Goksun, Kuntay & Naigles, 2008; Lee & Naigles, 2008). This article investigates whether two-year-olds learning Japanese, another argument-drop language, make use of argument…

We report a syntactic priming experiment that examined whether children's acquisition of the passive is a staged process, with acquisition of constituent structure preceding acquisition of thematic role mappings. Six-year-olds and nine-year-olds described transitive actions after hearing active and passive prime descriptions involving the same or…
