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…

Purpose: The aim of this study was to compare the verbal and nonverbal cognitive profiles of children with specific language impairment (SLI) with problems predominantly in expressive (SLI-E) or receptive (SLI-R) language skills. These diagnostic subgroups have not been compared before in psychological studies. Method: Participants were…

The present study examined the longitudinal associations among birth weight status, maternal warmth, and children's cognitive competence within an at-risk sample (N = 1809) drawn from the Fragile Families and Child Wellbeing study. Of particular interest was whether birth weight moderated the associations between maternal warmth and indicators of…

Background: This study examined language development in young children with hearing loss and different types of additional disabilities (ADs). Method: A population-based cohort of 67 children who were enrolled in the Longitudinal Outcomes of Children with Hearing Impairment study took part. Language ability was directly assessed at 3 and 5 years…

The aim of this longitudinal study was to examine spelling acquisition in French children with developmental language disorder (DLD) over a school year. Through a fine-grained spelling error analysis, we investigated whether spelling profiles could be established in the DLD population. This study comprised three groups: a typically developing (TD)…

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…

The Peabody Picture Vocabulary Test (PPVT) is a widely used test of receptive vocabulary, but no researchers to date have examined the performance of low-educated, low-literate L2 adults, or compared these individuals' performances to their more highly educated peers. In this study, we used many-facet Rasch analysis and mixed-effects linear…

This paper attempts to investigate the repetition of Relative Clauses (RCs) in Mandarin children with Developmental Language Disorder (DLD) (aged 4; 5 to 6; 0) and their typically developing (TD) peers. The results of a sentence repetition task indicate that Mandarin children with DLD perform significantly worse than both groups of TD children,…

The current study assessed the impact of parents' dialogical storybook reading on their children's receptive vocabulary and reading attitudes. Forty parents and their preschoolers participated in the study. Parents were randomly assigned to experimental or control groups. The experimental group received dialogical storybook reading training.…

We examined language profiles of 2571 children, 30-68 months old, with autism spectrum disorder (ASD), other developmental disabilities (DD), and typical development from the general population (POP). Children were categorized as expressive dominant (ED), receptive dominant (RD), or nondominant (ND). Within each group, the ED profile was the least…

Gesture comprehension remains understudied, particularly in children with autism spectrum disorder (ASD) who have difficulties in gesture production. Using a novel gesture comprehension task, Study 1 examined how 2- to 4-year-old typically-developing (TD) children comprehend types of gestures and gesture-speech combinations, and showed better…

Children with autism spectrum disorder present with a variety of social communication deficits such as atypicalities in social gaze and verbal and non-verbal communication delays as well as perceptuo-motor deficits like motor incoordination and dyspraxia. In this study, we had the unique opportunity to study praxis performance in deaf children…

Purpose: This was an investigation of the dimensionality of oral and written language to test the hypothesis that a two-factor model with sound/word and sentence/discourse language levels would best fit language and literacy data for a population-based sample in the school-age years. Method: A stratified secondary data set of 1,500 participants…

Cognates are known to facilitate second language acquisition and use, as learners tend to assign to a new L2 word the meaning of a similar L1 word. Consequently, for L2 tests that rely largely on lexical items, performance may prove inflated for examinees whose L1 shares many cognates with the language being tested. This article examines the…

Research Findings: Promoting inhibitory control in preschoolers could increase the likelihood of positive developmental trajectories. Nevertheless, to date only a limited number of studies have focused on inhibitory control training, reporting mixed results. To examine the efficacy and the transfer effects of the training on preschoolers, seven…
