This paper investigates English-speaking children's acquisition of raising constructions (e.g. "John seems to Mary to be happy") and fnds an asymmetric effect of NP type on their comprehension: an improvement in performance is observed when a lexical NP is raised across a pronominal experiencer (e.g. "John seems to her to be…

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…

One important mechanism suggested to underlie the acquisition of grammar is rule learning. Indeed, infants aged 0 ; 7 are able to learn rules based on simple identity relations (adjacent repetitions, ABB: "wo fe fe" and non-adjacent repetitions, ABA: "wo fe wo", respectively; Marcus et al., 1999). One unexplored issue is…

Corpora of child language are essential for research in child language acquisition and psycholinguistics. Linguistic annotation of the corpora provides researchers with better means for exploring the development of grammatical constructions and their usage. We describe a project whose goal is to annotate the English section of the CHILDES database…

There are numerous models of how speech segmentation may proceed in infants acquiring their first language. We present a framework for considering the relative merits and limitations of these various approaches. We then present a model of speech segmentation that aims to reveal important sources of information for speech segmentation, and to…

The study examines strategies multilingual children use to interpret grammatical relations, focusing on their two primary languages, Lajamanu Warlpiri and Light Warlpiri. Both languages use mixed systems for indicating grammatical relations. In both languages ergative-absolutive case-marking indicates core arguments, but to different extents in…

Thai has imperfective aspectual morphemes that are not obligatory in usage, whereas English has obligatory grammaticized imperfective aspectual marking on the verb. Furthermore, Thai has verb final deictic-path verbs that form a closed class set. The current study investigated if obligatoriness of these grammatical categories in Thai and English…

How might syntactic bootstrapping apply in Turkish, which employs inflectional morphology to indicate grammatical relations and allows argument ellipsis? We investigated whether Turkish speakers interpret constructions differently depending on the number of NPs in the sentence, the presence of accusative case marking and the causative morpheme.…

Fikkert (1994) analyzed a large corpus of Dutch children's early language production, and found that they often add targetless syllables to their words in order to create bisyllabic feet. In this note we point out a methodological problem with that analysis: in an important number of cases, epenthetic vowels occur at places where grammatical…

Parent report instruments adapted from the MacArthur-Bates Communicative Development Inventories (CDI) examined vocabulary development in children aged 0 ; 8 to 2 ; 6 for two Chinese languages, Mandarin (n = 1694) and Cantonese (n = 1625). Parental reports suggested higher overall scores for Mandarin- than for Cantonese-speaking children from…

In an experiment investigating aspects of children's comprehension of sentences containing the connective "if," young children judged correct and reversed "Y if X" and "If X, Y" sentences as "sensible" or "silly." The comprehension of the role of "if" in sentences appears to be a…

Reports on research that sought to clarify Brown's (1973) research on acquisition order, syntactic complexity, semantic complexity, and the relationship among the three. (Author/AM)

Describes early word usage in four children aged 1.6 to 1.9. The research investigated the children's use of words whose referents are unknown to them. (Author/AM)

Examined effects of direct intervention on language learning. Using a toy manipulation task, 18 children aged 3;6 to 4;6 were systematically taught linguistic structures beyond their developmental grasp. Solid improvement was found in the experimental conditions; no significant improvement was noted in control conditions, showing that the language…

Compares Lodge's (1979) examples of children's use of the past tense in pretend play with examples of the use of other moods and of modal auxiliaries. (AM)
