Multiple contemporary theories emphasize the quantity and quality of child vocalizations for promoting spoken language acquisition. Yet, empirical evidence for facilitating vocal development is strikingly lacking including for children with autism spectrum disorder (ASD) who have difficulty developing language. We evaluate use of contingent…

The purpose of this review was to assess the effectiveness of tablet-based speech-generating devices (SGDs) in improving communication skills for individuals with autism spectrum disorder (ASD). A total of 31 single-case design intervention studies involving 84 individuals with ASD were reviewed and included in the analysis. We calculated Tau-U to…

Language difficulties exert profound negative effects on the cognitive and social development of autistic children. Pivotal Response Treatment (PRT) is a promising intervention for improving social communication in autistic children, but there is a lack of a comprehensive examination of language functions. This study aimed to investigate the…

Children with autism spectrum disorder (ASD) may struggle with verbal behavior related to recall in various contexts. However, relatively little research has evaluated methods for improving recall among this population, and even fewer from a verbal behavior perspective. One socially important set of skills that relies upon a behavioral repertoire…

Social Stories (SS) serve as a catalyst to increase social engagement for children with autism. While numerous studies have examined the impact of SS on behavior, the research has mostly focused on static, paper-based stories. This study breaks new ground by examining Interactive Social Stories (ISS), which offer a more inclusive and dynamic…

Echolalia, a language phenomenon whereby individuals imitate the speech of others, is commonly used by children and adults with autism. Research into the underlying nature and meanings associated with this repetitive behaviour is characterised by a lack of conceptual definitions and conflicting opinions about the functions of echolalia. A scoping…

Many autistic children require support to meet their learning needs. Given the heterogeneity within the autism spectrum it is plausible that different types of support might be better suited to different children. However, knowledge on what interventions work best for which children is limited. We examined the outcomes of autistic preschool-aged…

Children with autism spectrum disorder (ASD) who are also minimally verbal may require specialized interventions to promote the development of vocalizations. Preliminary research supports an innovative procedure called response contingent stimulus-stimulus pairing (SSP) as a potentially effective procedure to promote vocalizations. The primary aim…

Parents play a significant role in the educational development of their children. However, there is little research around utilizing parents to collect data on their children's language skills. In particular, children with autism oftentimes demonstrate delays in the acquisition and use of language. Having information on a child's language…

Naturalistic language interventions are commonly recommended to educators when teaching children to reliably share their wants, interests, and feelings with others. Recommendations include providing focused attention on a child and embedding multiple instructional opportunities within and across activities. Although such practices are commonly…

The purpose of this study was to determine the effectiveness of a peer mediated intervention to increase social communication acts of preschool children with autism spectrum disorder (ASD). Utilizing a single-subject A-B design across four peer dyads, I examined the overall effectiveness of the intervention in relation to specific nonverbal,…

The use of speech-generating devices (SGD) in early interventions for children with autism spectrum disorder (ASD) can improve communication and spoken language outcomes. The purpose of this study was to describe children's responsiveness to SGD input modeled by a social partner during adult-child play interactions over a 24-week intervention…

This systematic review evaluated the effect of speech interventions with the addition of speech generating devices on vocalizations of children with autism spectrum disorder (ASD) and complex communication needs. This review synthesized information across 18 studies published in the past three decades (1990-2023) with the primary focus on the…

Background: Children with autism spectrum disorder (ASD) may experience challenges with verbal communication (VC) and task engagement (TE) in daily and academic activities. Antecedent-based interventions (ABI) have been explored as evidence-based practices (EBP) to improve VC and TE for children with ASD. The purpose of this study was to examine…

Baseline child characteristics may predict treatment outcomes in children with or at elevated likelihood of developing autism (EL-ASD). Little is known about the role of child sensory and language features on treatment outcome. Participants were randomly assigned to a parent-mediated intervention or control condition. Analyses explored the…
