In learning language, children must discover how to interpret the linguistic significance of phonetic variation. On some accounts, receptive phonology is grounded in perceptual learning of phonetic categories from phonetic distributions drawn over the infant's sample of speech. On other accounts, receptive phonology is instead based on phonetic…

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 dissertation extracted 17,291 questions from Aki, Ryo, and Tai and their mother's spontaneously produced speech data available in the CHILDES database (MacWhinney, 2000; Oshima-Takane & MacWhinney, 1998). The children's age ranged from 1;3 to 3;0. Their questions were coded for (1) yes/no questions that include a sentence-final…

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…

The study sought to isolate and identify patterns occurring in language interactions between mothers and their nonhandicapped and Down Syndrome children. Data were collected as part of a 3-year study of language interaction. Twenty nonhandicapped (NH) and 20 Down Syndrome (DS) children and their mothers were evaluated via a demographic inventory,…

Investigation of French mothers' (N=6) use of pronouns to refer to their infants during free play showed that third- and first-person pronouns occurred more often in the context of affect-oriented activities than in goal-directed activities. Second-person pronoun usage occurred more frequently in goal-directed activities. (Author/CB)

Measures fathers' and mothers' linguistic involvement in the development of communication between young siblings--infants and toddlers. In a laboratory setting, 39 families, each with a mother, a father and two children, were videotaped in semistructured activities. Results suggest that fathers very actively direct sibling interactions, especially…

A longitudinal study of twenty-four (24) Hebrew-speaking mother-infant dyads during discussions of recent events indicated that mothers commented on a small set of events and tended to mark events with exclamations or formulaic expressions that gradually progressed to a true description of events as the children got older. (Author/CB)

This study was designed to examine complexity of maternal language to 4-, 6-, and 8-month-old male and female infants in a laboratory situation as measured by mean length of utternace (MLU), frequencies of certain sentence types, and other syntactic indices. Subjects were 36 mothers and their infants. There were six male and six female infants at…

Microanalyses of unstructured videotaped interactions of three mother-infant dyads revealed dramatic shifts in dyadic vocalization patterns from primarily overlapping to primarily alternating. These results suggest that the emergent patterns reflect increased potential for coordination within the dyad, which may be capitalized on by mother and…

In order to determine (1) the major speech characteristics of mothers and fathers and (2) the relationship between parental input and child language development, a longitudinal analysis of parents' input language was conducted during the period in which four first-born children progressed from no words to the stable use of one-word utterances in…

Discusses the modifications in the direction of simplified and more linear language (American Sign Language) used by deaf mothers with their deaf children. (EKN)

This study reports a replication of an earlier study by Kilbourne and Ginsberg (1980) which indicated the occurrence of a transition from predominantly coacting to predominantly alternating infant-mother vocalization patterns. In addition, the present study examined the modulating influences of nursing activity and mother's focus of attention upon…

Examines whether vocal exchanges between preverbal infants and their mothers show characteristics similar to those found to be typical of conversational exchanges between competent adult speakers. (HOD)

Examines issues relating to similarity neighborhoods of words in children's lexicons. Young children's receptive vocabularies were analyzed for three-phoneme, four-phoneme and five-phoneme words. The pattern of the original results from Charles-Luce & Luce (1990) was replicated. (18 references) (Author/CK)
