Background: Language development is critical for children's life chances. Promoting parent-child interactions is suggested as one mechanism to support language development in the early years. However, limited evidence exists for a causal effect of parent-child interactions on children's language development. Methods: Data from the Language in…

Mental State Talk (MST) is utterances describing invisible mental aspects. The first aim of this study was to investigate the characteristics of Parental MST and Child MST and their concurrent association in a Swedish population, and the second aim was to relate these MST measures to the children's general language abilities. Seventy-seven dyads…

Understanding the sequential associations between caregiver responsivity and child communication is pivotal for enhancing child outcomes and guiding effective interventions. This dissertation study evaluates the LENA Start™ on caregiver-child communication, focusing on sequential association between caregiver and child communicative behaviors.…

This study explored responsive and linguistic parent input features during parent-child interactions and investigated how four input categories related to children's production of diverse, simple sentences. Of primary interest was parent use of responsive, simple declarative input sentences. Responsive and linguistic features of parent input to 20…

This study investigated differences in adult-child language interactions when parents and their three-to-four-year old children engage in wordless book reading, text-and-picture book reading and a small-world toy play activity. Twenty-two parents recorded themselves completing each activity at home with their child. Parent input was compared…

Pointing plays a significant role in communication and language development. However, in spoken languages pointing has been viewed as a non-verbal gesture, whereas in sign languages, pointing is regarded to represent a linguistic unit of language. This study compared the use of pointing between seven bilingual hearing children of deaf parents…

High-quality communicative interactions between caregivers and children provide a foundation for children's social and cognitive skills. Although most studies examining these types of interactions focus on child language outcomes, this paper takes another tack. It examines whether communicative, dyadic interactions might also relate to child…

The rate at which young children are directly spoken to varies due to many factors, including (a) caregiver ideas about children as conversational partners and (b) the organization of everyday life. Prior work suggests cross-cultural variation in rates of child-directed speech is due to the former factor, but has been fraught with confounds in…

Both the amount "and" responsiveness of adult language input contribute to the language development of autistic and non-autistic children. From parent-child interaction footage, we measured the amount of adult language input, overall parent responsiveness, and six discrete parent responsive behaviours ("imitations, expansions,…

To address the variability of naturalistic developmental behavioral intervention outcomes, the current study sought to isolate the effects of the instructional strategies of caregiver-mediated naturalistic developmental behavioral interventions. In this comparative efficacy trial, mothers of 111 autistic children (18-48 months) were randomized to…

It is well established in Australian research and policy literature that children attending schools in regional, rural, and remote locations will benefit from access not only to experiences and interactions offered in their own communities but also to the sorts of experiences available to those in more populated areas of Australia as well. Virtual…

Children acquire language embedded within the rich social context of interaction. This paper reports on a longitudinal study investigating the developmental relationship between conversational turn-taking and vocabulary growth in English-acquiring children (N = 122) followed between 9 and 24 months. Daylong audio recordings obtained every 3 months…

Researchers agree that early literacy activities, like book sharing and parent-child play, are important for stimulating language development. We hypothesize that book sharing is most powerful because it elicits more interactive talk in young children than other activities. Parents of 43 infants (9-18 months) made two daylong audio recordings…

Preliminary findings from a follow-up study of 33 children, assessed for their socioemotional development from 18 months of age, are presented. At 77 months, they were evaluated again in a laboratory context, recording on video a situation of discussion of a conflict with the caregiver and then coding these videos using the CIB instrument.…

This meta-analysis aims to clarify the relationship between teacher-child interaction and children's outcomes in language, mathematics, literacy, social development, and self-regulation based on the perspective of the Classroom Assessment Scoring System (CLASS). A total of 24 studies with 139 independent effect sizes and 67,919 participants were…
