Maternal input influences language development in children with Down syndrome (DS) and typical development (TD). Telegraphic input, or simplified input violating English grammatical rules, is controversial in speech-language pathology, yet no research to date has investigated whether mothers of children with DS use telegraphic input. This study…

Many children learn language, in part, from the speech of non-native speakers who vary in their language proficiency. To investigate the influence of speaker proficiency on the quality of child-directed speech, 29 mothers who were native English speakers and 31 mothers who were native speakers of Spanish and who reported speaking English to their…

Parent-child interaction is critical for early language and literacy development. Parent training programs have proliferated to support early interactions. However, many environmental and psychosocial factors can impact the quality of parent-child language and literacy interactions as well as training program outcomes. This preliminary randomized…

Caregiver speech is not a static collection of utterances, but occurs in "conversational exchanges," in which caregiver and child dynamically influence each other's speech. We investigate (a) whether children and caregivers modulate the prosody of their speech as a function of their interlocutor's speech, and (b) the influence of the…

This study assessed the status of te reo Maori, the indigenous language of New Zealand, in the context of New Zealand English. From a broadly representative sample of 6327 two-year-olds ("Growing Up in New Zealand"), 6090 mothers (96%) reported their children understood English, and 763 mothers (12%) reported their children understood…

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…

This study examined the vocabulary development of Norwegian second language (L2) learners with Urdu/Punjabi as their first language (L1) at two time-points from kindergarten to primary school, and compared it to the vocabulary development of monolingual Norwegian children. Using path models, the associations between number of picture books in the…

In this article we report two studies: a detailed longitudinal analysis of errors in "wh"-questions from six German-learning children (age 2 ; 0-3 ; 0) and an analysis of the prosodic characteristics of "wh"-questions in German child-directed speech. The results of the first study demonstrate that German-learning children…

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 study investigates the development of English multiword negation, in particular the negation of zero marked verbs (e.g. "no sleep", "not see", "can't reach") from a usage-based perspective. The data was taken from a dense database consisting of the speech of an English-speaking child (Brian) aged 2;3-3;4 (MLU 2.05-3.1) and his mother. The…

Using an events-history approach with 40 child-mother dyads, researchers examined prediction from three indexes of children's language, starting at 0;9, and mothers' verbal responsiveness at 0;9 and 1;1, investigating development of language milestones in year 2. Together, children's initial propensities to speak and mothers' responsiveness at the…

Describes a study which examined the relationship between mother's speech and the rate of child syntax growth for 22 two-and-a-half-year-old children. Results suggest that linguistic experience does contribute to syntax development but that the relation between linguistic input and language growth is different for different domains of language and…

A study investigating mothers' ideas of appropriate speech to children aged 1;6-3;6 looked at the explicitness of action directives given. Results support several theories and the notion that differences in mothers' language use reflect their ideas of what the child can understand. (MSE)

Discusses the variation and stability of mother speech patterns across individuals. Analyzes the functionally coded speech of 11 mothers and provides a typology of mother styles, based on the intentions of mothers to direct or converse with their children. (EKN)

Analyzes mothers' speech in free-play interactions with their 12- to 27-month-old children for frequency and type of fantasy relationships. Results indicate that the older the child, the more fantasy talk a mother is likely to use. (EKN)
