The early language environment, especially high-quality, contingent parent-child language interactions, is crucial for a child's language development and later academic success. In this secondary analysis study, 89 parent-child dyads were randomly assigned to either the Music Together® (music) or play date (control) classes. Children were 9- to…

Maria Montessori's work remains popular and influential around the world. She provided fascinating descriptions of her observations of children's learning. Yet at the heart of her work is a lacuna: the issue of how children learn their first language. For Montessori, it was a marvel, a miracle--but a mystery. We argue that the later philosophy of…

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…

This longitudinal study investigated parents' different pretend play behaviors (substitution, animation, and role enactment) to their infants during free play and the bidirectional links with infants' vocabulary development at 14 months (Time-1: N = 34, M[subscript age] = 14.23 months) and 20 months (Time-2: N = 34, M[subscript age] = 20.33…

Infants begin to produce abstract "math" words -- such as numbers (e.g., "two"), spatial terms (e.g., "down"), and magnitude words (e.g., "more") -- during their second postnatal year. Math words, as all words, are likely learned in the home setting during interactions with caregivers. However, everyday…

Communication is commonly viewed as connecting people through conscious symbolic processes. Infants have an immature communication toolbox, raising the question of how they form a sense of connectedness. In this article, we propose a framework for infants' communication, emphasizing the subtle unconscious behaviors and autonomic contingent signals…

Adolescent mothers (AMs) often experience limited academic and financial attainment and higher rates of mental health disorders, which may affect their relationships with their children. Although children of AMs are at higher risk for developmental delays, there is no clear evidence of the relationships between mother characteristics and child…

Purpose: It is widely acknowledged that parental input plays an important role in typical language development. Less is known about the input provided to children with (suspected) developmental language disorder (DLD) or those at risk for DLD. These children may not benefit from parental input in the same way as their typically developing peers,…

Purpose: This study evaluates the impact of temporal synchrony between maternal touch and speech on children's early language development. It investigates whether the proportion of word-touch co-occurrence, overlap, and alignment precision in maternal input influences language acquisition, hypothesizing that such synchrony boosts infants'…

Researchers have demonstrated the important contribution of mothers' sensitive parenting to children's developing cognition over the first 5 years of life, yet studies examining sensitivity beyond the early years, controlling for earlier effects, are limited. In this exploratory study, we examined the developmental pathways through which mothers'…

The opportunity for language-building interactions, and specifically conversational turn-taking with a caregiver, is a critical foundation for enhancing a child's language development. In this secondary analysis of conversational turns, 89 parent-child dyads who previously completed 1 year of either weekly Music Together (music) or play date…

The first years of life are critical for language development. Numerous studies indicate that actively participating in music creates a neural processing advantage in brain regions that support language development. Nevertheless, shared social characteristics between music and language may also play a role in explaining the benefits of music…

Developmental research confirms the importance of early parental language input for building children's vocabulary and language skills (Hart & Risley, 1995). While reading with a caregiver is a common way for language input to occur, the approaches parents utilize often fail to capitalize on techniques for improving language and pre-literacy…

Engaged communication between mother and a child in their early developmental stages is one of the predictors of children's development of higher-order thinking skills. For deaf children, this engaged communication between mother and child hinges on the home language environment (HLE) being fully accessible to the child. This research uses…

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…
