Purpose: Miniature linguistic systems (also known as matrix training) is a method of organizing learning targets to achieve generative learning or recombinative generalization. This systematic review is aimed at determining whether matrix training is effective for individuals with autism spectrum disorder (ASD) in terms of improving recombinative…

An experimental crossover research design was utilized to investigate the effects of multimedia-enhanced instruction on the vocabulary acquisition of dual language learners in the early childhood age range. Sixteen 3-year-olds stratified by classroom and randomly assigned to condition participated in an eight-week intervention that incorporated…

We investigated the effect of real-time technology-enhanced performance-based feedback delivered during three different routines on teacher practice and child outcomes. Participants were three early childhood special education teachers and three focus preschool children identified with autism spectrum disorder. We used a multiple-probe single-case…

Purpose: This study investigated the early rule-based sentence productions of 3- and 4-year-old children with severe speech disorders who used single-meaning graphic symbols to communicate. Method: Ten 3- and 4-year-olds requiring the use of augmentative and alternative communication, who had largely intact receptive language skills, received…

Purpose: This study was conducted to evaluate the effects of a conversation-based intervention on the expressive vocabulary and grammatical skills of children with severe motor speech disorders and expressive language delay who use augmentative and alternative communication. Method: Eight children aged from 8 to 13 years participated in the study.…

Lexicon Pirate was originally developed as a strategy intervention programme to treat lexical disorders of pre-school children. To evaluate the therapy's effectiveness for school-age students, a randomized controlled trial (RCT, N = 157) was conducted. Based on a pre--post-test design, the programme's impacts were compared with a control group…

Purpose: In this study, the authors examined the effects of the Teach-Model-Coach-Review instructional approach on caregivers' use of four enhanced milieu teaching (EMT) language support strategies and on their children's use of expressive language. Method: Four caregiver-child dyads participated in a single-subject, multiple-baseline study.…

Teachers working with children with autism spectrum disorders were surveyed to determine the characteristics of children with whom Social Stories are used, how extensively they are employed and the types of behaviors targeted by teachers; how and why teachers use Social Stories (including the extent to which Social Stories conform to recommended…

This study evaluated the "missing-item" language intervention with two moderately to severely retarded students (ages five and six) in a special class setting. The missing-item format produced effects in requests for targeted snack items and, after generalization training, a requesting repertoire that was durable and generalized across…

Three case studies are reported, illustrating use of Structured Role Play Therapy in teaching moderately language-delayed children, aged 4-6, to produce specifically targeted grammatical forms and to generalize production to sentences not included in therapy activities. The role-playing resulted in rapid increases in production accuracy of…

This study compared the relative effectiveness of imitative intervention and conversational recast language intervention applied to grammatical morpheme and complex sentences in 21 children with specific language impairment. The conversational procedure was found to require fewer presentations to first spontaneous use and to produce more…
