Background: Parental input plays a central role in typical language acquisition and development. In autism spectrum disorder (ASD), characterized by social communicative and language difficulties, parental input presents an important avenue for investigation as a target for intervention. A rich body of literature has identified which aspects of…

Pragmatics lies at the point where language meets the social world and encompasses both the linguistic and the social dimensions of communication. However, the relationship between pragmatic abilities, other language skills, and socio-cognitive aspects such as mentalizing is still a matter of wide debate. This study sets out to investigate the…

Background: Children's language abilities set the stage for their education, psychosocial development and life chances across the life course. Aims: To compare the efficacy of two preschool language interventions delivered with low dosages in early years settings (EYS): Building Early Sentences Therapy (BEST) and an Adapted Derbyshire Language…

Associations between home learning opportunities, parental growth mindset (the belief that intelligence is malleable), and children's academic skills have been documented primarily in European descent communities. Less is known about other communities. This study examined associations among home learning opportunities, parental mindsets, and child…

As an initial step of a larger grant-funded project, this pilot study examined how providing preschool teachers in low socio-economic urban areas with a traditional professional development workshop and subsequent coaching on dialogic reading (DR) strategies affected their storybook reading. Effects on children's receptive and expressive language…

Purpose: This study examined the efficacy of the Vocabulary Acquisition and Usage for Late Talkers (VAULT) treatment in a version that manipulated the length of clinician utterance in which a target word was presented (dose length). The study also explored ways to characterize treatment responders versus nonresponders. Method: Nineteen primarily…

While it is established that parental "wh"-questions, as a high-quality language input, are associated with child language outcome, less is known about the role of children's "wh"-questions in their language development. This study examines whether children's "wh"-questions during a dinnertime conversation are…

We examined differences between children with autism spectrum disorder and typically developing children over an 8-month period in: (a) longitudinal associations between expressive and receptive vocabulary and (b) the extent to which caregiver utterances provided within an "optimal" engagement state mediated the pathway from early…

This study explored participation- and impairment-based outcomes for 24 late-to-talk toddlers (M age = 20.46 months, SD = 3.09, 62.5% male) whose parents participated in Target Word™, The Hanen Program® for Parents of Children who are Late Talkers in community clinics across Ontario. Parents completed the MacArthur-Bates Communicative Development…

Purpose: In this review article, meta-analysis was used to summarize research investigating language skills in maltreated children. Method: A systematic search of published studies was undertaken. Studies were included in the meta-analysis if they investigated language skills in groups comprising maltreated and nonmaltreated children. Studies were…

Background: Evidence suggests that language and social, emotional and behavioural (SEB) difficulties are associated in children and adolescents. When these associations emerge and whether they differ by language or SEB difficulty profile is unclear. This knowledge is crucial to guide prevention and intervention programmes for children with…

Infants from low-socioeconomic status (SES) households hear a projected 30 million fewer words than their higher-SES peers. In a recent study, Hirsh-Pasek et al. (Psychological Science, 2015; 26: 1071) found that in a low-income sample, fluency and connectedness in exchanges between caregivers and toddlers predicted child language a year later…

The growth rate and the composition of expressive lexicon was studied in a sample of 903 infants between the age of 0;8 and 1;4 whose parents completed the Estonian adaptation of the MacArthur-Bates Communicative Development Inventory-Words and Gestures. As expected, older children had on average larger vocabularies compared to younger children.…

Research on immediate effects of background television during mother-infant toy play shows that an operating television in the room disrupts maternal communicative behaviors crucial for infants' vocabulary acquisition. This study is the first to examine associations between frequent background TV/video exposure during mother-infant toy play at…
