Purpose: We measure typically developing monolingual child Spanish speakers' lexical development with a range of standard expressive and receptive tests. We also measure their comprehension of sentences with the existential quantifier "algunos" "some" to determine their abilities to generate "some, but not all" scalar…

An utterance such as "Show me the large rabbit" potentially generates a "contrastive inference," i.e., the article "the" and the adjective "large" allow listeners to pragmatically infer the existence of other entities having the same noun (e.g. a "small" rabbit). The primary way to measure…

How to help babies and young children right from birth to become competent in talking as well as emergent literacy is illustrated by research findings as well as with specific clinical stories. Both kinds of knowledge can serve to galvanize parents and teachers to increase awareness of infant and preschool language development and the crucial role…

The main goal of this article is to study the respective role of language typology and context on the noun to verb asymmetry in caregiver speech. The speech of 20 French- and 20 Turkish-speaking mothers addressed to their children in two different situations (book-reading and toy-play) were analysed in terms of noun to verb ratio as well as in…

In two experiments, one hundred ninety-two 3-year-olds, 4-year-olds, and adults heard a novel word for a target object and then were asked to extend the label to one of two test objects, one matching in shape-based object category (the shape match) and the other matching in a property other than shape (the property match). We independently…

Children's production of bare nominals is universal. When acquiring languages disallowing bare nominals, children will develop from the bare to the non-bare stage. However, Mandarin nominals may appear bare or non-bare in various positions with all kinds of interpretations. This dissertation conducts two acquisition studies to examine the…

This study investigates the acquisition of the discourse/pragmatic notion of topic, based on an experimental task eliciting topic vs. focus subjects. In spoken French, these are obligatorily realized as dislocated vs. nondislocated noun phrases. The results provide overwhelming evidence for the early mastery of topic, even by the youngest children…

This paper documents the occurrence of form variability through diminutive "wordplay", and examines whether this variability facilitates or hinders morphology acquisition in a richly inflected language. First, in a longitudinal speech corpus of eight Russian mothers conversing with their children (1.6-3.6), and with an adult, the use of diminutive…

Examines (1) preschool children's production of multiple, hierarchically related labels; (2) the pragmatic consequences of the inherent asymmetry of inclusion relations; and (3) the influence of morphology (modifier plus noun constructions vs. simple lexemes) at the subordinate level. Performance shows an inability to label objects flexibly at…

Investigates the ability of 32 two-year-old children to use syntactic (i.e., form class) and semantic (i.e., type of referent) information to interpret the meaning of new nouns. Subjects were taught either a common noun or a proper noun for a block-like or animal-like object and then asked to select the named toy. (Author/CB)

Examines pragmatic factors that bias English-speaking children to produce more of the nouns and fewer of the verbs than they know. Data from 44 parent-child dyads in the New England directory of the CHILDES data base were analyzed. (Author/VWL)

In a recent paper [Lidz, J., Gleitman, H., & Gleitman, L. (2003). Understanding how input matters: Verb learning and the footprint of universal grammar. "Cognition," 87, 151-178], we provided cross-linguistic evidence in favor of the following linked assertions: (i) Verb argument structure is a correlate of verb meaning; (ii) However, argument…

Two hundred forty English-speaking toddlers (24- and 36-month-olds) heard novel adjectives applied to familiar objects (Experiment 1) and novel objects (Experiment 2). Children were successful in mapping adjectives to target properties only when information provided by the noun, in conjunction with participants' knowledge of the objects, provided…

Inferences about linguistic competence in children are typically based on spontaneous speech. Children's use of complex object and adverbial noun phrase is seen as a reflection of pragmatic factors. Similar adult patterns indicate children's lack of subject clauses may be due to the nature of spontaneous speech. (CHK)

The findings from a number of recent studies indicate that, even in cases of successful bilingual first language acquisition, the possibility remains of a certain degree of crosslinguistic influence when the choice between syntactic options is affected by discourse pragmatics. In this study we focussed on the use of referring expressions, prime…
