This study examined early Hebrew verb acquisition, highlighting CDS-CS relations across inflectional and derivational verb learning. It was carried out on a corpus of longitudinal dense dyadic interactions of two Hebrew-speaking toddlers aged 1;8-2;2 and their parents. Findings revealed correlated patterns within and between CDS and CS corpora in…

This paper examines the way children younger than two use non-verbal devices (i.e., deictic gestures and communicative functional acts) and pay attention to discourse status (i.e., prior mention vs. newness) of referents in interactions with caregivers. Data based on semi-naturalistic interactions with caregivers of four children, at ages 1;00,…

Onomatopoeia are frequently identified amongst infants' earliest words (Menn & Vihman, 2011), yet few authors have considered why this might be, and even fewer have explored this phenomenon empirically. Here we analyze mothers' production of onomatopoeia in infant-directed speech (IDS) to provide an input-based perspective on these forms.…

The present study investigates flexibility of verb use in the early stages of English multiword development, and its relationship with patterns attested in the input. The data is taken from a case study of a monolingual English-speaking boy aged 2; 5-2; 9 and his mother while engaged in daily activities in the home. Data were coded according to…

The phonetic characteristics of canonical babbling produced by Korean- and English-learning infants were compared with consonant and vowel frequencies observed in infant-directed speech produced by Korean- and English-speaking mothers. For infant output, babbling samples from six Korean-learning infants were compared with an existing English…

Examines naturalistic adult-to-child speech of Italian middle class mothers to determine which patterns characterize linguistic input to infants. Because Italian is a pro-drop language, adult-to-child speech revealed bias toward more salient semantic and morphological significance of verbs relative to nouns, and verbs will likely occupy…

The present research investigated whether children's referential choices for verb arguments are motivated by pragmatic features of discourse referents across different developmental stages, not only for children learning null argument languages but also for those learning overt argument languages. In Study 1, the form (null, pronominal, or…

Followup to earlier report that focused on initial uses of first 10 words produced by 4 children is presented. Results of analysis of subsequent use of these 40 words is presented. Findings indicate that the role of linguistic input in early lexical development may decline sharply once a child has established initial uses for words. (24…

Explores the possibility that the early predominance of infinitival forms in children acquiring Dutch as their first language is related to patterns in the language input. Analyzed a corpus of utterances addressed by two Dutch-speaking mothers to their 2- and 3-year-old sons. Root infinitive utterances amounted to 10%, and auxiliary-plus…

Many recent generativist models attribute grammatical knowledge to young children on the basis that children's language patterns the same way as the target adult language. It has been proposed that the child acquires this knowledge early on in development by a process of parameter setting. Wexler (1996) presents the "Very Early Parameter Setting…

Maternal infant-directed speech in Mandarin Chinese and Turkish (two mother-child dyads each) was examined to see if cues exist in input that might assist infants' assignments of words to lexical and functional item categories. Results show that sets of distributional, phonological, and acoustic cues distinguishing lexical and functional items are…
