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.…

This study compared the lexical-semantic organization skills of bilingually developing deaf children in American Sign Language (ASL) and English with those of a monolingual hearing group. A repeated meaning-association paradigm was used to assess retrieval of semantic relations in deaf 6-10-year-olds exposed to ASL from birth by their deaf…

Parent-child conversations are a potential source of children's developing understanding of the biological domain. We investigated patterns in parent-child conversations that may inform children about biological domain boundaries. At a marine science center exhibit, we compared parent-child talk about typical sea animals with faces (fish) with…

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…

Topic choice, topic synchrony, and utterance function during mother-child play sessions at age 3 were examined in 32 late talkers and 21 comparison children, matched at intake on age, socioeconomic status, and nonverbal ability. Late talkers and comparison children did not differ in number of utterances, topic initiation, topic synchrony, use of…

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…

Research and theory on language acquisition and language socialization are examined and compared. The language acquisition perspective is that the central question is how children acquire forms and patterns of language, with syntax at the core, so early and so rapidly. From the viewpoint of language socialization, the issue is not only of…

Reports on two studies of the similarities and differences in communicative style between Japanese- and English-speaking parents. Findings reveal that Japanese mothers pay considerable attention to their children's narratives and facilitate frequent turn exchanges, whereas English-speaking mothers allow their children to take long monologic turns…

Compares the prosodic modifications in mothers' and fathers' speech to preverbal infants in American and British English, French, German, Japanese, and Italian. Speech samples were instrumentally analyzed to measure mean fundamental frequency, variability, utterance, duration, and pause duration. (67 references) (Author/CB)

A comparison is presented of a mother's language to her Down Syndrome two-year-old and his normally developing twin. When interacting with the Down Syndrome twin, the mother used shorter mean length of utterance, greater type-token ratio, more confirmations, more verbal directives, fewer yes-no and true questions, and more directive questions.…

A study investigated the patterns of question use in Mandarin Chinese-speaking parents' and caregivers' interactions with children, and how they characterize social class differences. Subjects were 10 children, aged 21-23 months, and their families, selected from immunization records in Beijing, China. Parents were all native speakers of Mandarin…

This paper discusses findings from a study of the speech patterns of 10 mothers interacting with their own younger child, their own older child, and with an adult. Results are discussed in terms of the temporal-acoustic pattern and content of the mothers' speech. Two claims are made about the kinds of speech a child hears: (1) The flow of speech…

Comparison of maternal speech to three-month-olds between American (N=20) and Japanese (N=20) mother-infant dyads revealed that infant gaze affected the intended functions of maternal speech differently for the two groups. Cultural differences were also seen in the nature of function-form and function-referent relationships. (Author/CB)

This longitudinal pilot study, which extends Veneziano's (1987) work on phonetically and semantically contingent maternal response types, compared, microanalytically and globally, maternal response types and mother-child dyadic interactions of normally developing and Down syndrome children. Participants were three normally developing infants, five…
