Children learn math concepts long before they enter school. Across all cultures, children are exposed to number and spatial language to varying degrees during everyday home routines. Yet most studies of math talk occur in the lab and target non-Hispanic, English-speaking families. We expanded inquiry to the spontaneous math language (i.e., number…

Purpose: Fathers play a critical but underresearched role in their children's cognitive and linguistic development. Focusing on two-parent families with a mother and a father, the present longitudinal study explores the amount of paternal input infants hear during the first 2 years of life, how this input changes over time, and how it relates to…

Purpose: This study was conducted in a large Midwestern metropolitan area to examine the language environments at home and in center-based childcare for young children who are living in poverty. We compared child language use and exposure in the home and childcare settings using extended observations with automated Language Environment Analysis to…

Research Findings: This study investigated the long-term interrelations among children's language competencies, their home literacy environment (HLE), and 3 aspects of socioemotional development from ages 3 to 8, controlling for characteristics of the child and family. For this sample of 547 typically developing German children, parents and…

This study examined the joint effects of home environment and center-based child care quality on children's language, communication, and early literacy development, while also considering prior developmental level. Participants were 95 children (46 boys), assessed as toddlers (mean age = 26.33 months; Time 1) and preschoolers (mean age = 68.71…

The purpose of the study was to evaluate the language status of 120 young, Latino dual language learners living in poverty in the United States. Maternal language input and home language and literacy environments were examined with regard to language development at 24 and 36 months. Results suggested that even when combining English and Spanish…

This longitudinal assessment concentrated on the relation between the home literacy environment (HLE) and early language acquisition during infancy and toddlerhood. In study 1, after controlling for socio-economic status, a broadly defined HLE predicted language comprehension in 50 infants. In study 2, 27 children returned for further analyses.…

Home environment quality is a well-known predictor of school readiness (SR), although the underlying processes are little known. This study tested two hypotheses: (a) child language mediates the association between home characteristics (socioeconomic status and exposure to reading) and SR, and (b) genetic factors partly explain the association…

Major innovations are becoming available for research in language development and disorders. Among these innovations, recent tools allow naturalistic recording in children's homes and automated analysis to facilitate representative sampling. This study employed all-day recordings during the 2nd year of life in a child exposed to three languages,…

The belief that a child has to abandon his home language to learn English implies that the young brain has limited learning capacity. Early childhood teachers need to help families understand that children can learn two languages at the same time. What matters is that the infant/toddler is in an effective language-learning environment, whether it…

A methodological study of 33 2-year-olds shows that child speech occurs at about the same level in different settings (the familiar home vs. the unfamiliar laboratory), but that children speak more and in more differentiated ways with different people (mother vs. stranger). (Author/VWL)

Intended for parents and others caring for young children, this viewer's guide and videotape leads adults along the path of child's language acquisition and demonstrates how to use a language-rich environment to communicate with infants, toddlers, and preschool children in ways to foster language development. The first half of the guide presents…

This study investigated patterns of acquisition of English and Japanese by a toddler, aged 16-23 months, living in Japan. The child's mother and father are British and Japanese, respectively. The focus of the study was on early grammatical morpheme and transformational rule acquisition as demonstrated in the child's utterances. The study is…
