Purpose: Parental language input (PLI) has reliably been found to influence child language development for children at risk of language delay, but previous work has generally restricted observations to the preschool years. The current study examined whether PLI during the early years explains variability in the spoken language abilities of…

Fourteen-month-old infants are unable to link minimal pair nonsense words with novel objects (Stager & Werker, 1997). Might an adult's productions in a word learning context support minimal pair word-object association in these infants? We recorded a mother interacting with her 24-month-old son, and with her 5-month-old son, producing nonsense…

This paper investigates how negation develops in the speech of a Turkish-speaking child in the very early stages of language acquisition. The study features the video recordings of a child between the ages of 19 and 22 months and the analyses of negative forms in the recorded data. The development of negation in parent-child interactions is…

Purpose: This study examined relationships among family characteristics, caregiver change in use of strategies, and child growth in spoken language over the course of a parent-implemented language intervention (PILI) that was developed to address some of the challenges associated with the fragile X syndrome (FXS) phenotype. Method: Participants…

This study examined the nature of parents' shared reading with their preschoolers between and across two different alphabet trade books. The "busy" book contains more sentences and words per page, more complex illustrations per page, and the target letter takes up less of the page and appears in the same colour as the text. The…

Children use language structures as a basis for learning how to read. Therefore, literacy learning for young children must incorporate the child's personal use of oral language. It is their personal oral language that supports them as they attempt new concepts and become better readers. Because of the important role that oral language plays in a…

Individuals with sex chromosome trisomies (SCTs) have an increased risk of language delays and impairments. However, there are only a few data relative to their language development in early childhood. The present study aimed to investigate the preverbal skills shown by a group of 8-month-old children with SCTs to assess the presence of a possible…

This study investigated whether parent perceptions of their own and their child's levels of talkativeness were related to objective measures recorded via the Language Environment Analysis (LENA) System. Parents of 258 children aged 7 to 60 months completed a questionnaire on which they rated how much they and their child talked. Six months…

This study examined potential differences in vocabulary found in picture books and adult's speech to children and to other adults. Using a small sample of various sources of speech and print, Hayes observed that print had a more extensive vocabulary than speech. The current analyses of two different spoken language databases and an assembled…

Using an observational task followed by an experimental task with an Intermodal Preferential Looking Paradigm, we examined the effect of input on children's acquisition of class extension rules by investigating the relationship between the amount of polysemous noun-verb pairs in French-speaking 2-year-olds' input and both their spontaneous…

Mothers' mental state language in conversation with their preschool children, and children's preschool attachment security were examined for their effects on children's mental state language and expressions of emotional understanding in their conversation. Children discussed an emotionally salient event with their mothers and then relayed the…

Study of how the verbal component of "babytalk" affected three-month-olds' (N=40) vocal qualities suggested that conversational turn-taking facilitated a speak-listen pattern of infant vocalizations and indicated that what adults "say" to infants influences what infants "say" in response.

In this study, maternal speech was analyzed acoustically to see whether mothers spoke with the same simplitude in both real and play situations. Results showed that mothers use both pitch height and pitch range to introduce the preverbal infant to the difference between play and nonplay situations. (Author/JL)

Investigated the use of "mama" or similar sounds referred to as "mama" by 75 infants less than 6 months of age. Parents were directed to listen for "mama" sounds and to note the sounds made, the age of onset, whether the sounds appeared to be directed to any person or persons, or whether they appeared to have a purpose. (Author/VWL)

This study examines the distribution of nouns and verbs in maternal speech to one year olds. Mothers and children were videotaped. Nouns and verbs in maternal speech were coded for frequency, sentence position, and occurrence with grammatical inflections. Frequency of nouns and verbs varied with context. (33 references) (KM)
