The present study aimed at investigating the contextual stability, the contextual continuity and the concurrent associations between maternal measures (general language, communicative functions and mind-mindedness) and child measures (total number of word types and tokens) in two different contexts, free-play and mealtime. To this purpose, the…

We explored whether supported (SJE) or coordinated joint engagement (CJE) between mothers recruited from the community and their 24-month-old children who were slow-to-talk at 18 months old were associated with child language scores at ages 24, 36, and 48 months (n = 197). We further explored whether SJE or CJE modifed the concurrent positive…

Maternal depression and anxiety are potential risk factors to children's language environments and development. Though existing work has examined relations between these constructs, further work is needed accounting for both depression and anxiety and using more direct measures of the home language environment and children's language development.…

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…

Previous research indicates that features of speech during mother-toddler interactions are dependent on the situational context. In this study, we explored language samples of 69 mother-toddler dyads collected during standardized toy play and book-reading situations across two countries, Germany and the United States (US). The results showed that…

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…

Twenty-nine infants aged 1;1 and their mothers were videotaped while interacting with toys for 18 minutes. Six experimental stimuli were presented to elicit infant communicative bids in two communicative intent contexts--proto-declarative and proto-imperative. Mothers' verbal responses to infants' gestural and non-gestural communicative bids were…

This study examined (a) the relationship between gesture and speech produced by children with specific language impairment (SLI) and typically developing (TD) children, and their mothers, during shared book-reading, and (b) the potential effectiveness of gestures accompanying maternal speech on the conversational responsiveness of children.…

In this study we investigated adopted Chinese girls' expressive English language outcomes in relation to their age at adoption, chronological age, length of exposure to English and developmental risk status at the time of adoption. Vocabulary and phrase utterance data on 318 girls were collected from the adoptive mothers using the Language…

Phonological neighborhood analyses of tow children's expressive lexicons, maternal input, and an adult lexicon were conducted. In addition to raw counts and frequency-weighted counts, neighborhood size was calculated as the proportion of the lexicon to which each target word is similar, to normalize for vocabulary size differences. Analyses…

Predictive relations were examined between measures of 20 mothers' behavioural and verbal general and specific responsiveness and intrusive and supportive directiveness and their children's subsequent expressive vocabularies during three developmental periods with endpoints at the beginning, middle, and end of the second year: 0;10 to 1;1, 1;1 to…

Data from two-year-old children and mothers were collected concerning age at which she began to read to child, frequency of home reading, number of stories read per week, frequency of visits by child to library. Picture-book reading exposure was more strongly related to receptive than expressive language. Age of onset of home reading routines was…

Videotapes of 45 subjects at 1;1 and 1;8 showed preexisting differences between mothers of earlier and later talkers as early as 1 year, 1 month. When the sample was divided according to stylistic preference at 1;8 (referential or expressive), associations between maternal language at 1;1 and mean length of utterance at 1;8 emerged only for the…
