Is noun dominance in early lexical acquisition a widespread or a language-specific phenomenon? Thirty Singaporean bilingual English-Mandarin learning toddlers and their mothers were observed in a mother-child play interaction. For both English and Mandarin, toddlers' speech and reported vocabulary contained more nouns than verbs across book…

Many studies have addressed the question of the relative dominance of nouns over verbs in the productive vocabularies of children in the second year of life. Surprisingly, cross-class (noun-to-verb and verb-to-noun) relations between these two lexical categories have seldom been investigated. The present longitudinal study employed observational…

Because of its structural characteristics, specifically the prevalence of verb types in infant-directed speech and frequent pronoun-dropping, the Italian language offers an attractive opportunity to investigate the predictive effects of input frequency and positional salience on children's acquisition of nouns and verbs. We examined this…

This study investigated how forty-six mothers modified their talk about familiar and unfamiliar nouns and verbs when interacting with their children with Down Syndrome (DS), language impairment (LI), or typical development (TD). Children (MLUs < 2·7) were group-matched on expressive vocabulary size. Mother-child dyads were recorded playing with…

Twenty-nine infants aged 1;1 and their mothers were videotaped while interacting with toys for 18 minutes. Six experimental stimuli were presented to elicit infant communicative bids in two communicative intent contexts--proto-declarative and proto-imperative. Mothers' verbal responses to infants' gestural and non-gestural communicative bids were…

Ten mothers were observed prospectively, interacting with their infants aged 0 ; 10 in two contexts (picture description and noun description). Maternal communicative behaviours were coded for volubility, gestural production and labelling style. Verbal labelling events were categorized into three exclusive categories: label only; label plus…

Parents of 592 children between the age of 0 ; 8 and 1 ; 4 completed the Estonian adaptation of the MacArthur-Bates Communicative Development Inventory (ECDI Infant Form). The relationships between comprehension and production of different categories of words and gestures were examined. According to the results of regression modelling the…

Six tests of the spontaneous speech of twenty-one English-speaking children (1 ; 10 to 2 ; 8; MLUs 1[middle dot]53 to 4[middle dot]38) demonstrate the presence of the syntactic category determiner from the start of combinatorial speech, supporting nativist accounts. Children use multiple determiners before a noun to the same extent as their…

This study examines the distribution of nouns and verbs in maternal speech to one year olds. Mothers and children were videotaped. Nouns and verbs in maternal speech were coded for frequency, sentence position, and occurrence with grammatical inflections. Frequency of nouns and verbs varied with context. (33 references) (KM)

Fourteen mothers and their children participated in a storybook reading session in which the mothers taught their children both a basic-level count noun and a situation-restricted count noun for a series of object drawings. Analysis of mothers' spontaneous teaching strategies revealed that they typically taught a basic-level count noun before a…

This study shows that the noun bias in early vocabularies rests only in part on the acquisition of object names. An analysis of vocabulary composition from 45 children at I;8 indicates that more nouns are acquired than all other word classes but that only about half of the nouns acquired are the names of basic level object classes (BLOCs). (KM)

Mothers were found to respond differentially to their infants' object-related gestures. Pointing was found to have an especially strong correlation with mothers' object-labelling responses, which in turn were predictive of the child's object-naming vocabulary. (Author/JB)

Investigates structural and pragmatic aspects of caregiver input in English and Korean that relate to the early development of nouns and verbs. Twenty mothers in each language were asked to interact with their children in two contexts: Book-reading and toy-play. Data suggest that systematic comparisons of caregiver input within and across…

Examined individual growth rates in definitional skill over a period of 3 to 6 years, for 68 low-income children. Results of the study support the notion that definitional skill is related to being part of an academic culture; low-income mothers, whose formal schooling is complete, generally do not give oral definitions to simple nouns as well as…

This study investigated the use of generic noun phrases by preschool children and their mothers. Results indicate striking differences in the way generics and non-generics are distributed in the speech of both groups, suggesting generic noun phrases differ in their semantics and conceptual organization from non-generics and may reflect children's…
