Research-supported knowledge about how children develop language is considered foundational for high-quality instruction and as such, measuring and developing teachers' knowledge has been emphasized across the field of early childhood. However, there is a critical gap in understanding how this static knowledge gained through pre-service and…

This study examines the landscape of childcare providers (CPs) in Saudi Arabia, focusing on their pivotal role in supporting children's language development. While fundamental, understanding CPs' knowledge of child language development, self-efficacy, and professional training remains limited in this context. This study aims to provide a…

This paper reports a preliminary evaluation of the [Talkable] 10-week language learning programme. This training programme aims to help caregivers provide a rich language learning environment in a child's first 3 years of life through the provision of evidence-based information and practical strategies to promote language development delivered…

Background: Shared reading interventions can impact positively on preschool children's language development and on their caregiver's attitudes/behaviours towards reading. However, a number of barriers may discourage families from engaging with these interventions, particularly families from lower socio-economic status (SES) backgrounds. We…

Purpose: Understanding variability sources in early language interaction is critical to identifying children whose development is at risk and designing interventions. Variability across socioeconomic status (SES) groups has been extensively explored. However, SES is a limited individual clinical indicator. For example, it is not generally directly…

We designed a parent-directed home-visiting intervention targeting socioeconomic status (SES) disparities in children's early language environments. A randomized controlled trial was used to evaluate whether the intervention improved parents' knowledge of child language development and increased the amount and diversity of parent talk.…

This study evaluates the effects of Age of Exposure to English (AoEE) and Current Input/Output on language performance in a cross-sectional sample of Spanish-English bilingual children. First- (N = 586) and third-graders (N = 298) who spanned a wide range of bilingual language experience participated. Parents and teachers provided information…

This study investigated the role of parenting knowledge of infant development in children's subsequent language and pre-literacy skills among White, Black and Latino families of varying socioeconomic status. Data come from 6,150 participants in the Early Childhood Longitudinal Study-Birth Cohort. Mothers' knowledge of infant development was…

We examined whether preschoolers' ontological knowledge would influence lexical extension. In Experiment 1, four-year-olds were presented with a novel label for either an object with eyes described as an animal, or the same object without eyes described as a tool. In the animal condition, children extended the label to similar-shaped objects,…

An increasing emphasis is being placed on the importance of speech, language and communication (SLC) development during the first two years of life, since this contributes to cognitive ability and to later educational outcomes. This article explores what disadvantaged, first-time mothers know and understand about three key contributors to positive…

Two experiments examined young children's use of the familiarity principle when learning language. Found that even 2-year-olds successfully identified the referent of a proper name as the individual with whom the speaker was familiar. However, only 5-year-olds reliably succeeded at determining the individual with whom the speaker was familiar…

Language and vocabulary represent the very foundation of learning to read and write. Children who do not develop strong oral language skills and vocabulary in these early years will find it difficult to keep pace with their peers. Children use the natural medium of language for thinking. Those who acquire a substantial vocabulary are often able to…

Examined the impact of an educational intervention on knowledge of speech-language development among 66 caregivers of children. An educational handout containing information about basic speech and language development milestones was provided to the intervention group. Results of pre- and posttests indicated that the intervention group increased…

Examined how object shape, taxonomic relatedness, and prior lexical knowledge influenced children's overextensions (e.g., referring to pomegranates as apples). Researchers presented items that disentangled the three factors and used a novel comprehension task where children could indicate negative exemplars. Error patterns differed by task and by…

This paper examines two- to five-year-old children's knowledge of inversion in English yes/no questions through a new experimental study. It challenges the view that the syntax for inversion develops slowly in child English and tests the hypothesis that grammatical competence for inversion is present from the earliest testable ages of the child's…
