Stunting has been negatively associated with children's development. We examined the range of height by testing hypotheses: (a) height is positively associated with children's development, with associations moderated by inflammation and (b) home environments characterized by nurturance and early learning opportunities is positively associated with…

Play is a powerful influence on children's learning and parents can provide opportunities to learn specific content by scaffolding children's play. Parent-child synchrony (i.e., harmony, reciprocity and responsiveness in interactions) is a component of parent-child interactions that is not well characterized in studies of play. We tested whether…

Previous studies have suggested that parents may support the development of theory of mind (ToM) in their child by talking about mental states (mental state talk; MST). However, MST has not been sufficiently explored in deaf children with cochlear implants (CIs). This study investigated ToM and availability of parental MST in deaf children with…

Although evidence has suggested that social skills interventions yield social and symptom benefits for autistic children, significant variability in outcomes between studies has raised important questions regarding efficacy and moderators of intervention outcomes (i.e., which interventions yield positive effects and which autistic children are…

The aim of this study is twofold: To examine if deafness is invariably associated with deficits in executive function (EF) and to investigate the relationship between sign language proficiency and EF in deaf children of deaf parents with early exposure to a sign language. It is also the first study of EF in children acquiring Polish Sign Language.…

The purpose of this study was to investigate the role of variability in teaching prepositions to preschoolers with typical development (TD) and developmental language disorder (DLD). Input variability during teaching can enhance learning, but is target dependent. We hypothesized that high variability of objects would improve preposition learning.…

This study used data from Early Childhood Longitudinal Study -- Birth Cohort (ECLS-B) and examined the relations between children's Head Start exposure and their early academic skills (i.e., language, literacy, and math skills) in the United States. Two groups of children who shared similar socio-economic status and disability status but received…

Prior work has found links between consistency in toddler handedness for the fine motor skill role-differentiated bimanual manipulation (RDBM), and language development at 2 and 3 years of age. The current study investigated whether consistency in handedness from 18 to 24 months (N = 90) for RDBM predicts receptive and expressive language…

Assessing vocabulary knowledge is an important part of establishing language proficiency in bilingual children. The crosslinguistic lexical tasks (CLTs) provide a framework for testing vocabulary development in three-to-six year-olds using a standard procedure and comparable items for multiple languages. This study describes the development of the…

Children with autism spectrum disorder (ASD) and hyperlexia (HPL) have both advanced word reading skills and a reading comprehension disorder, alongside impaired oral language. We developed a unique, parent-supported, tablet-based intervention aiming to improve oral and reading comprehension at the word-, phrase- and sentence-level, for…

A relatively large number of children with autism spectrum disorder (ASD) exhibit disruptive behavioral problems. While accumulating data have shown behavioral parent training programs to be efficacious in reducing disruptive behaviors for this population, there is a dearth of literature examining the impact of such programs across the range of…

Purpose: Childhood apraxia of speech (CAS) is hypothesized to arise from deficits in speech motor planning and programming, but the influence of abnormal speech perception in CAS on these processes is debated. This study examined speech perception abilities among children with CAS with and without language impairment compared to those with…

Bilingual children demonstrate varying levels of proficiency in each of the two languages to which they are exposed. Even though it is widely acknowledged that bilingual children are not a homogenous group, existing studies on dual-language profiles in bilingual children have focused on expressive language profiles. In this study, we used the…

Purpose: This study examined vocabulary profiles in young cochlear implant (CI) recipients and in children with normal hearing (NH) matched on receptive vocabulary size to improve our understanding of young CI recipients' acquisition of word categories (e.g., common nouns or closed-class words). Method: We compared receptive and expressive…

This study investigated bilingualism effects on the production of focus in 5- to 9-year-old Cantonese-English bilingual autistic children's L1 Cantonese, compared to their monolingual autistic peers as well as monolingual and bilingual typically developing children matched in nonverbal IQ, working memory, receptive vocabulary and maternal…
