The positive effects of shared book reading on vocabulary and reading development are well attested (e.g., Bus, van Ijzendoorn, & Pellegrini, 1995). However, the role of shared book reading in GRAMMATICAL DEVELOPMENT remains unclear. In this study, we conducted a construction-based analysis of caregivers' child-directed speech during shared…

We report three studies (one corpus, two experimental) that investigated the acquisition of relative clauses (RCs) in Finnish-speaking children. Study 1 found that Finnish children's naturalistic exposure to RCs predominantly consists of non-subject relatives (i.e. oblique, object) which typically have inanimate head nouns. Study 2 tested…

In two studies we use a pointing task to explore developmentally the nature of the knowledge that underlies three- and four-year-old children's ability to assign meaning to the intransitive structure. The results suggest that early in development children are sensitive to a first-noun-as-causal-agent cue and animacy cues when interpreting…

This study investigates the coordination of matrix and subordinate clauses within finite complement-clause constructions. The data come from diary and audio recordings which include the utterances produced by an American English-speaking child, L, between the ages 1;08 and 3;05. We extracted all the finite complement-clause constructions that L…

We investigated whether children at the ages of two and three years understand that a speaker's use of the definite article specifies a referent that is in common ground between speaker and listener. An experimenter and a child engaged in joint actions in which the experimenter chose one of three similar objects of the same category to perform an…

In this article we report two studies: a detailed longitudinal analysis of errors in "wh"-questions from six German-learning children (age 2 ; 0-3 ; 0) and an analysis of the prosodic characteristics of "wh"-questions in German child-directed speech. The results of the first study demonstrate that German-learning children…

Young children answer many questions every day. The extent to which they do this in an adult-like way -- following Grice's Maxim of Quantity by providing the requested information, no more no less -- has been studied very little. In an experiment, we found that two-, three- and four-year-old children are quite skilled at answering…

Analyzing the development of the noun-to-verb ratio in a longitudinal corpus of four Chintang (Sino-Tibetan) children, we find that up to about age four, children have a significantly higher ratio than adults. Previous cross-linguistic research rules out an explanation of this in terms of a universal noun bias; instead, a likely cause is that…

Three- and four-year-old children were asked predicate-focus questions ("What's X doing?") about a scene in which an agent performed an action on a patient. We varied: (i) whether (or not) the preceding discourse context, which established the patient as given information, was available for the questioner; and (ii) whether (or not) the patient was…

English-speaking children make pronoun case errors producing utterances where accusative pronouns are used in nominative contexts ("me do it"). We investigate whether complex utterances in the input ("Let me do it") might explain the origin of these errors. Longitudinal naturalistic data from seventeen English-speaking two- to four-year-olds was…

Using the weird word order methodology (Akhtar, 1999), we investigated children's understanding of SVO word order in French, a language with less consistent argument ordering patterns than English. One hundred and twelve French children (ages 2;10 and 3;9) heard either high or low frequency verbs modelled in either SOV or VSO order (both…

The study investigates the development of English multiword negation, in particular the negation of zero marked verbs (e.g. "no sleep", "not see", "can't reach") from a usage-based perspective. The data was taken from a dense database consisting of the speech of an English-speaking child (Brian) aged 2;3-3;4 (MLU 2.05-3.1) and his mother. The…

Determined the degree to which a sample of one child's creative utterances related to utterances that the child previously produced. Utterances were intelligible, multi-word utterances produced by the child in a single hour of interaction with her mother. Results suggest the high degree of creativity in early English child language could be…
