This systematic review examined definitions of "nonverbal" or "minimally verbal" and assessment measures used to evaluate communication in intervention studies focusing on improving expressive verbal communication in children with autism spectrum disorder (ASD). We reviewed sample size, number of participants, participant age,…

Purpose: The aims of this systematic review are to (a) synthesize the literature on interventions targeting expressive communication in adults with autism spectrum disorder and (b) evaluate the effectiveness of the interventions. Method: The literature search resulted in 7,196 articles. The research team used 2 reviewers and consensus for…

The traditional recommendation for sequencing speaker and listener instruction has been to teach listener skills prior to teaching speaker skills. In a review of the research literature prior to 2011, Petursdottir and Carr (2011) concluded that research did not support this recommendation. We reviewed the most recent research on the efficiency of…

This study compared pronoun use in individuals with autism to their typically developing peers via meta-analysis and systematic review of 20 selected articles to examine differences in overall pronoun usage as well as in personal, ambiguous, possessive, reflexive, and clitic pronoun usage. Summary effects indicated significant differences between…

Naturalistic developmental behavioral intervention is an emerging class of interventions for young children with autism spectrum disorder. The present article is a meta-analysis of outcomes of group-design studies (n = 27) testing interventions using naturalistic developmental behavioral intervention strategies. Small, significant positive effects…

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…

Children with autism spectrum disorders (ASDs) often demonstrate delays in early language and literacy skills. Shared reading, the practice of adults reading aloud to children while using behaviors (e.g., asking questions) that are meant to promote interaction between the adult and child, is an intervention that has had positive effects on those…

The purpose of this review was to identify naturalistic language interventions for increasing spontaneous expressive language (defined in this review as absence of verbal prompt or other verbalization from adults or peers) in young children with autism spectrum disorder. Also, the methodological rigor and effectiveness of each study were evaluated…

This review of research examines investigations that have focused on the effect of reinforcer specificity on the acquisition of both language comprehension and production skills by learners with severe handicaps. Issues regarding the use of intervention strategies that employ reinforcer specificity are discussed. (Author/JW)

Review of literature on indicators of the effectiveness of language intervention programs for autistic children showed that mitigation in echolalia was a critical characteristic, as it implied that the prerequisites for language were accessible through speech. Children whose speech ranged from mutism to unmitigated echolalia had a more negative…

Two approaches to intervention geared to autistic children's characteristics are presented: one stressing speech and the other sign and speech. Some findings relevant to implementation of simultaneous sign and speech are discussed, and due to observed variability in processing and responsiveness to intervention, the need for individual programing…

This article discusses the potential of applying research based on the principles of stimulus equivalence and related phenomena to the investigation and remediation of language disabilities, particularly with individuals with intellectual disabilities and autism. It describes studies which have applied an equivalence framework to different aspects…
