Echolalia can negatively impact multiple skill areas in children diagnosed with autism spectrum disorder (ASD), including skills related to academic and social performance. The purpose of this study was to employ a multiple probe across participants design to evaluate the effects of tact training on delayed echolalia in three children in China…

This paper analyses disfluencies and ungrammatical expressions in the speech of 11-13-year-old Finnish-speaking boys with ASD (N = 5) and with neurotypical development (N = 6). The ASD data were from authentic group therapy sessions and neurotypical data from teacher-led group discussions. The proportion of disfluencies and ungrammatical…

Although pragmatic speech impairments have been found across the autism spectrum, how these manifest in minimally verbal (MV) individuals with autism spectrum disorder (ASD) has not been studied. We compared the pragmatic speech profiles of MV (n = 50) and verbally fluent (VF) individuals with ASD (n = 50; 6-21 years-old) based on natural language…

Although perseverative speech is a common characteristic of individuals with high-functioning neurodevelopmental disabilities, little is known about the operant functions of these verbalizations. We conducted analogue functional analyses of perseverative speech for 2 students using reinforcement contingencies that included alone, attention,…

Music-based speech language interventions have shown promise to support young children with autism, other speech and language deficits, and Dual Language Learners (also known as DLL, English Language Learners, or ELL). Online edtech learning programs may produce greater positive outcomes for children by including parents as mediators of the…

Purpose: This study aimed to provide detailed descriptive information about the speech of a heterogeneous cohort of children with autism spectrum disorder (ASD) and to explore whether subgroups exist based on this detailed speech data. High rates of delayed and disordered speech in both low-verbal and high-functioning children with ASD have been…

Children with autism spectrum disorder (ASD) who have limited speech are often taught to communicate using a speech-generating device (SGD). We evaluated procedures for teaching a mand for information (i.e., "Where" is [item]?) using an interrupted behavior chain procedure. In Experiment 1, all participants (3 children with ASD who…

Purpose: Previous studies have shown enhanced pitch and impaired time perception in individuals with autism spectrum disorders (ASD). However, it remains unclear whether such deviated patterns of auditory processing depending on acoustic dimensions would transfer to the higher level linguistic pitch and time processing. In this study, we compared…

South Australian, Lyndall Hendrickson AM (1917-2017) led a lifetime of achievements as a prodigy, concert violinist, polio survivor, violin instructor and teacher of language and music to non-verbal autistic students. Her career halted when she contracted poliomyelitis at the age of 34. To regain motor skill, Hendrickson researched theories of…

Sotos syndrome is a congenital overgrowth syndrome associated with intellectual disability. This study investigated communicative abilities of children with Sotos syndrome (n = 31), using the Children's Communication Checklist, second edition. A cross-syndrome approach was used to establish the specificity of these abilities. Children with…

Background: Sleep problems are common in children with autism spectrum disorder (ASD). There is also emerging evidence that sleep quality influences language learning in typical development. However, there is a gap within the literature in regards to sleep and developmental language disorder in children (DLD). Objectives: The aims of this study…

Accurate diagnosis of Autism Spectrum Disorder (ASD) at an early age is increasingly sought so that the child and family can access early intervention and supports. However, not all children neatly fit into the diagnostic criteria for ASD, and additional assessment and supports are often required as providers continue to evaluate the possibility…

Although choice of task has been effective in reducing noncompliance, it may provide an opportunity to escape from less-preferred tasks. We used a reversal design to evaluate the effects of choice of a low-preference task sequence on noncompliance, task engagement, and duration to complete activities across two individuals with autism spectrum…

Ohio's public schools provide special education services to children with disabilities as early as preschool. Every year, the Ohio Department of Education reports the number of preschool children who received state-funded special education services during the previous year. The 2016-2017 school year had an overall increase of 1,142 (5.9 percent)…

Individuals with autism spectrum disorder (ASD) often exhibit disordered speech prosody, but sources of disordered prosody remain poorly understood. We explored patterns of temporal alignment and prosodic grouping in a speech-based metronome repetition task as well as manual coordination in a drum tapping task among Cantonese speakers with ASD and…
