Although vocabulary size is thought to index children's language abilities, an increasing body of work suggests that regularities in children's vocabulary composition, particularly the proportion of shape-based nouns (e.g., cup), support language development. Here we examine initial vocabulary composition in children with hearing loss following…

This study compared the use of delivering a single instruction (e.g., Who is it?) versus varied instructions (e.g., What's their name? Who is this? What about this one?) when teaching three children diagnosed with autism spectrum disorder (ASD) novel expressive label targets via direct telehealth. The present investigation utilized an adapted…

Background: Prelinguistic communication complexity refers to the use of different communication forms such as eye gaze, gestures and vocalisations and the degree to which these forms are coordinated and how directed to a communication partner. To date, little is known about the relationship between prelinguistic communication complexity and…

Purpose: The present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA). Method: Participants…

Researchers have demonstrated that dialogue-based intelligent tutoring systems (ITS) can be effective in assisting students in learning. However, little research has attempted to explore the necessity of equipping dialogue-based ITS with one of the most important capabilities of human tutors, that is, maintaining polite interactions with students,…

This study investigated the acquisition of early expressive vocabulary among young children who are deaf and hard-of-hearing (DHH; n = 68) using auditory technology (hearing aids and cochlear implants). Parents completed a standardized vocabulary checklist, which allowed analyses of (i) the size of their child's spoken vocabulary; (ii) composition…

The present study investigated the relationship between lexicon and grammar in individuals who use graphic symbol-based aided augmentative and alternative communication (AAC). Data came from 60 transcripts of generalization sessions that were part of two previous intervention studies, aimed at improving the expressive vocabulary and grammar of 12…

The gestures produced by children with intellectual disability (ID) in spatial tasks are rarely considered, although they have a supporting role in the formation of thought. In this research study, we analyzed the number of gestures, the type of gestures, and their role in the expression of knowledge of students with ID. Twenty students (12-17…

Background: Early intervention is recommended for pre-school children with low language. However, few robustly evaluated language interventions for young children exist. Furthermore, in many interventions the theoretical underpinnings are underspecified and the 'active ingredients' of the interventions not tested. This paper presents a…

Providing training for women intending to re-enter or increase their employment options in the science, technology, engineering, and mathematics (STEM) fields must address women's mathematics anxiety. Addressing women's anxiety is essential given that mathematics is often viewed as the foundation upon which the other STEM careers are built. This…

Objective: To provide an in-depth examination of whether pragmatic, expressive, receptive, and narrative language are associated with the social and academic functioning of children with ADHD. Method: Children with ADHD (n = 46) and neurotypical comparison (NC) children (n = 40) aged 7 to 11 years completed tasks measuring expressive, receptive,…

On average, deaf and hard-of-hearing (DHH) children have difficulty developing expressive spoken vocabulary comparable to hearing peers. Yet, there are no evidence-based practices to guide classroom instruction for teachers of the deaf. Retrieval practice--a robust learning strategy--has been shown to improve children's retention of vocabulary,…

The current study reports the results of a randomized controlled trial examining the impact of the Getting Ready parent-engagement intervention on expressive language skills of children (N = 267) with developmental concerns upon entry into preschool. Latent growth for expressive language and moderating roles of parental stress and parental…

Despite the importance of identifying children with developmental language delay, no accurate screening instruments are available for 3-year-olds. The aim of the present study is to compare the accuracy of the General Language Screen (GLS), focusing on receptive and expressive language and intelligibility with the accuracy of the VTO Language…

Purpose: The aim of this study was to explore relations between speech sound disorder severity and selective mutism in a group of children with 7q11.23 duplication syndrome (Dup7), a genetic condition predisposing children to childhood apraxia of speech (CAS) and other speech sound disorders and to anxiety disorders, including selective mutism and…
