The clinical similarity among different neuropsychiatric disorders (NPDs) suggested a shared genetic basis. We catalogued 23,109 coding de novo mutations (DNMs) from 6511 patients with autism spectrum disorder (ASD), 4,293 undiagnosed developmental disorder (UDD), 933 epileptic encephalopathy (EE), 1022 intellectual disability (ID), 1094…

Purpose: This study was designed to test the incremental validity of more expensive vocal development variables relative to less expensive variables for predicting later expressive language in children with autism spectrum disorder (ASD). We devote particular attention to the added value of coding the quality of vocalizations over the quantity of…

Children with autism spectrum disorder benefit from early, intensive interventions to improve social communication, and parent-implemented interventions are a feasible, family-centered way to increase treatment dosage. The success of such interventions is dependent on a parent's ability to implement the strategies with fidelity. However,…

The use of robots to teach students with autism spectrum disorder communication skills has basis in the literature; however, research investigating the effects of teaching coding or programming of robotics to promote learning in STEM to this population has not yet been conducted. The purpose of the current study was to evaluate the effects of…

Research on teaching STEM, especially in the areas of teaching coding for students with ASD, is lacking. The purpose of the current study was to evaluate the effects of using model-lead-test to teach an elementary-aged student with ASD and severe problem behavior the following dependent variables: (a) calibrating the robot; (b) drawing tracks for…

This study examined the effects of participation of peer volunteers in the Transitions Program for young adults with Autism Spectrum Disorder (ASD), a program that facilitates social skills and social interactions. Participants in this study were peer volunteers in the Transitions Program. Each peer volunteer completed a questionnaire, following…

The co-occurrence of psychotic and autism spectrum disorder (ASD) symptoms represents an important clinical challenge. Here we consider this problem in the context of a computational psychiatry approach that has been applied to both conditions--predictive coding. Some symptoms of schizophrenia have been explained in terms of a failure of top-down…

Increased numbers of young children identified with autism combine with changing paradigms for service delivery models to create a need to ensure that information is available to facilitate implementation of effective practices in children's natural learning environments. A recent synthesis that identifies evidence-based practices (EBPs) for…

Video-based modeling is an evidence-based practice for teaching social and communication skills, functional and daily living skills, and some academic skills (i.e., math) to students with autism spectrum disorder. The efficacy of video-based modeling, however, has not yet been established for STEM skills related to science, technology, or…

Purpose: We present the first study of echolalia in deaf, signing children with autism spectrum disorder (ASD). We investigate the nature and prevalence of sign echolalia in native-signing children with ASD, the relationship between sign echolalia and receptive language, and potential modality differences between sign and speech. Method: Seventeen…

Educators have used narrative fiction to expand knowledge and facilitate awareness about underrepresented populations, including those with disabilities. This study is a content analysis of nine award-winning young-adult narrative fiction books with characters depicting individuals with ASD. The analysis yielded a total of 285 symptoms that were…

This article is intended to synthesize the broader literature investigating the effectiveness and salient features of interventions designed to enhance the social competence of youth and adults with autism spectrum disorder. Outcomes for adults with autism spectrum disorder remain poor with only minimal improvement shown for decades. Among 796…

A qualitative study of three parents and their toddlers with autism was conducted to investigate the communicative functions underlying parent-toddler interactions and how the instrumental or social nature of one partner's actions influenced the other's engagement. Parent-child interaction videos collected from a separate intervention study were…

Parent-child interaction videos collected from a separate intervention study were…

The prevalence of both bilingual children and children with autism spectrum disorder (ASD) is growing rapidly, and early childhood educators may be increasingly likely to encounter bilingual children with ASD in their classrooms. Because ASD significantly affects communication, many parents and professionals may have questions or concerns about…
