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…

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,…

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…

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,…

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…

Developmental difference is a common characteristic of autism spectrum disorder (ASD) with unclear sex differences. The current study included 610 children with ASD, aged between 2 and 7 years, with completed language profiles. We used a nonparametric item response theory model called Mokken scale analysis to examine the order of acquisition of…

The developmental, characteristics and educational competencies of students who need special education are developing slowly in compared to their agemates. This is because their expressive language is different. In order to overcome these challenges, assistive technologies can be used under the supervision of the teachers. In this paper, a person…

Joint attention and imitation are thought to facilitate a developmental cascade of language and social communication skills. Delays in developing these skills may affect the quality of children's social interactions and subsequent language development. We examined how responding to joint attention and object imitation skills predicted rate of…

The aim of this study was to investigate individual differences in mathematical problem-solving among 3- to 5-year-old children (N = 328; n[subscript 3-year-olds] = 115, n[subscript 4-year-olds] = 167, n[subscript 5-year-olds] = 46). First, we examined the extent to which children in this age group were able to solve open and closed non-routine…

Background: Previous studies have explored the size and word type composition (nouns, predicates, etc.) of expressive vocabularies of preschool children with Down syndrome, both spoken and signed. Separately, overall preferences for modality of expression have also been explored. Aims: To extend previous findings by describing the relationships…
