Parent input during interaction with young children varies across languages and contexts with regard to the relative number of words from different lexical categories, particularly nouns and verbs. Previous work has focused on spoken language input. Little is known about the lexical composition of parent input in American Sign Language (ASL). We…

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…

When talking to infants, adults, especially mothers, espouse a particular type of speech known as Infant-directed Speech (IDS) or "babytalk" or "babytalking" , which contains a set of specialized speech with simplified grammatical construction; more repetitive; and more grammatical than adult-directed speech. Specifically, this…

The syntactic structure of sentences in which a new word appears may provide listeners with cues to that new word's form class. In English, for example, a noun tends to follow a determiner ("a"/"an"/"the"), while a verb precedes the morphological inflection [ing]. The presence of these markers may assist children in…

This cross-linguistic study investigated whether the native language has any influence on lexical composition among Italian (N = 125) and Finnish (N = 116) very preterm (born at <32 gestational weeks) children at 24 months (controls: 125 Italian and 146 Finnish full-term children). The investigation also covered the effect of maternal education…

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…

Via naturalistic observations, parent interview, and direct assessments, we examined language proficiency, language use, and differentiation of a 3-year, 4-month-old bilingual child exposed to Mandarin and English via the "one parent-one language" principle. Although noun versus verb dominance has been explored across verb-based…

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…

Using an observational task followed by an experimental task with an Intermodal Preferential Looking Paradigm, we examined the effect of input on children's acquisition of class extension rules by investigating the relationship between the amount of polysemous noun-verb pairs in French-speaking 2-year-olds' input and both their spontaneous…

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 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…
