This study focuses on parental use of parentese: the acoustically exaggerated, clear, and higher-pitched speech produced by adults across cultures when they address infants. While previous research shows that parentese enhances language learning and processing, it is still unclear what drives the variability in the amount of parental parentese…

Children begin to show symptoms of neurodevelopmental disorders early on in their development. Providing early intervention that is culturally responsive to both families and the child receiving the service is vital for the child's growth. The purpose of this study was to qualitatively explore 14 Latin American Spanish-speaking parents' reactions…

Research Findings: Early elementary school is a crucial time for the development of executive functions, but less is known about the impact of parent-child narratives on executive function development in children of this age group. This study aims to investigate the influence of parental scaffolding styles in parent-child co-constructed narratives…

Children need to learn the demands of their native language in the early vocabulary development phase. In this dynamic process, parental multimodal input may shape neurodevelopmental trajectories while also being tailored by child-related factors. Moving beyond typically characterized group profiles, in this article, we synthesize growing evidence…

Numerous studies indicate that the language and literacy development of young children is highly contingent upon the construction of an enriching home literacy environment. Using sociocultural theory as a framework, in this article I explore how a bilingual child's language and literacy acquisition is embedded as a social practice within the home…

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…

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…

Previous research shows that infants of parents who are more likely to engage in socially contingent interactions with them tend to have larger vocabularies. An open question is "how" social contingency facilitates vocabulary growth. One possibility is that parents who speak in response to their infants more often produce larger…

Purpose: Talkers adapt their speech according to the demands of their listeners and the communicative context, enhancing the properties of the signal (pitch, intensity) and/or properties of the code (enhancement of phonemic contrasts). This study asked how mothers adapt their child-directed speech (CDS) in ways that might serve the immediate goals…

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.…

The number of U.S. children living in households with extended families has greatly increased in the last 4 decades. This demographic shift calls for a reevaluation of the impact of household size on children's development. Household density (HHD), measured as the ratio of people to bedrooms in a home, has been shown to negatively relate to…

What is vision's role in driving early word production? To answer this, we assessed parent-report vocabulary questionnaires administered to congenitally blind children (N = 40, Mean age = 24 months [R: 7-57 months]) and compared the size and contents of their productive vocabulary to those of a large normative sample of sighted children (N =…

Research on "parentese," the acoustically exaggerated, slower, and higher-pitched speech directed toward infants, has mostly focused on maternal contributions, although it has long been known that fathers also produce parentese. Given recent societal changes in family dynamics, it is necessary to revise these mother-centered models of…

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…
