Background: This study aimed to compare developmental courses of structural and pragmatic language skills in school-aged children with Williams syndrome (WS) and children with idiopathic intellectual disability (IID). Comparison of these language trajectories could highlight syndrome-specific developmental features. Method: Twelve monolingual…

This study moves beyond previous investigations to examine whether an educational intervention combining shared book reading with a vocabulary game increases children's vocabulary knowledge. Four-year-olds (N = 44) were randomly assigned to dyads in either an intervention (shared book reading plus vocabulary review game) or comparison condition…

This study moves beyond previous investigations to examine whether an educational intervention combining shared book reading with a vocabulary game increases children's vocabulary knowledge. Four-year-olds (N = 44) were randomly assigned to dyads in either an intervention (shared book reading plus vocabulary review game) or comparison condition…

The unique relation of language use (i.e., output) to language growth was investigated for forty-seven 30-month-old Spanish-English bilingual children (27 girls, 20 boys) whose choices of which language to speak resulted in their levels of English output differing from their levels of English input. English expressive vocabularies and receptive…

Parent-child interaction plays a crucial role in early language acquisition. In young typically developing children, direct and indirect relationships between parent gesture, child gesture and child language have been observed. Far less is known about these relationships in atypical language development. The present study investigated parent…

This study investigated contributors of English reading comprehension outcomes among predominantly U.S.-born 1st- and 3rd-grade (N = 73) dual language learners (DLLs) from Spanish-speaking, low-income homes who attend English-only instructional schools in the Southern region of the United States, which is experiencing historic rates of school-age…

Infants from low-socioeconomic status (SES) households hear a projected 30 million fewer words than their higher-SES peers. In a recent study, Hirsh-Pasek et al. (Psychological Science, 2015; 26: 1071) found that in a low-income sample, fluency and connectedness in exchanges between caregivers and toddlers predicted child language a year later…

Preschool teachers from a high-poverty, urban school district were trained to implement Story Talk, a book reading intervention designed to increase children's vocabulary and language development using supportive materials and strategic individualized coaching. Thirty-five teachers were randomly assigned by site to the intervention (20) or the…

This study aimed to investigate if a universal 24-week oral language and emergent literacy programme delivered to students in the first year of schooling positively impacts reading performance 2 years post intervention. Eighty-nine participants were second grade students from three primary schools in low socio-economic status areas. Using a…

This study examined the incidental acquisition of English prepositions by Arabic-speaking English as a foreign language (EFL) learners. Employing reading comprehension exercises as a treatment, we adopted the experimental design of a pre- and post-test to determine the effectiveness of the treatment on the participants' incidental acquisition of…

We investigated whether individual differences in overall receptive vocabulary knowledge measured at the beginning of the year moderated the effects of a kindergarten vocabulary intervention that supplemented classroom vocabulary instruction. We also examined whether moderation would offset the benefits of providing Tier-2 vocabulary intervention…

Research Findings: The present study compared effects of explicit instruction on and practice with the phonological form of words (form-focused instruction) versus explicit instruction on and practice with the meaning of words (meaning-focused instruction). Instruction was given via interactive storybook reading in the kindergarten classroom of…

Background: Late language emergence is a risk indicator for developmental language disorder. Parent-implemented early language intervention programmes (parent programmes) have been shown to have positive effects on children's receptive and expressive language skills. However, long-term effectiveness has rarely been studied. Additionally, little is…

This book provides a rich and unique longitudinal account of content and language integrated learning (CLIL). The chapters report on the findings from a large-scale, three-year research project undertaken at senior high school level in Sweden. The ecological perspective, with quantitative and qualitative methods, gives voice to both learners and…

This study investigates the relationship between nonword repetition (NWR) and vocabulary in 2-year-olds. Questions addressed are whether (1) NWR and vocabulary are associated, (2) phonotactic probability affects NWR, and (3) there is an interaction effect between phonotactic probability and vocabulary on NWR performance. The general aim of the…
