Establishing evidence- and research-based practices relies upon research synthesis of individual studies in reviews and meta analyses. Further summarizing scientific evidence about a specific topic by synthesizing reviews is an area of need to determine practices that have a strong evidence base and to identify areas of methodological weakness and…

Between 30 and 50% of individuals with Autism Spectrum Disorder (ASD) do not develop vocal language deemed functionally acceptable to meet their daily communication needs. As a result, individuals with ASD may require intervention alternatives to vocal speech, such as augmentative and alternative communication (AAC). However, very little is known…

This article explores the available research literature on language development and language interventions among deaf and hard of hearing (d/hh) children. This literature is divided into two broad categories: Research on natural languages (specifically American Sign Language and spoken English) and research on communication systems (specifically…

For d/Deaf and hard-of-hearing prereaders who communicate predominately in spoken and/or signed English (DHH-English), Teachers of the d/Deaf (TODs) read books aloud to increase English skills, auditory-verbal comprehension, sequencing skills, verbal reasoning, background knowledge, and sight word recognition. Teachers struggle to select…

Background: Children who are learning English as an Additional Language (EAL) may start school with smaller vocabularies than their monolingual peers. Given the links between vocabulary and academic achievement, it is important to evaluate interventions that are designed to support vocabulary learning in this group of children. Aims: To evaluate…

A six-year longitudinal evaluation was made of the effectiveness of the various early intervention strategies being emphasized in seven preschool programs for hearing-impaired children. (Author/DLS)

A multimodal intervention program designed for a nine-year-old with severe communication problems (secondary to cerebral palsy, receptive dysphasia, and auditory agnosia) combined manual signs and graphic symbols to help her communicate. The intensive, highly structured program had significant positive results. (Author/CB)

The use of nonspeech symbol sets (including manual signs and Blyssymbols) in language intervention with mentally retarded students is discussed. The selection and use of aided or unaided nonspeech symbol sets are considered, along with cognitive, sociocommunicative, technological, and motoric factors. (CL)

During an eight-month treatment regimen utilizing simultaneous sign/speech input, all of the words of a young girl with Down's Syndrome were recorded. Analyses revealed that most of the words she initially signed were later spontaneously spoken and that most of her signed productions evolved into spontaneous spoken productions. (Author/JDD)

Disfluencies in the verbal and signed language of a 10-year-old moderately mentally retarded boy were analyzed. Discussion addresses implications for the accurate characterization of stuttering in manual communication and appropriate approaches to management in such cases. (DB)

One member from each of two object pairs was assigned as a reinforcer during a generalized requesting intervention using manual signs or graphic symbols with two severely handicapped learners (age 18). Prior generalized request training and reinforcer use did not influence effectiveness of later instruction in acquisition and generalized use of…

Evaluates a comprehensive intervention program for deaf children under age three in Vancouver, British Columbia. Twelve subjects were compared with a matched sample of children undergoing less-systematic intervention. Results indicated more developmentally mature communication and higher quality interaction in families who had received…

This paper argues that current practices in total communication classrooms have basically assigned the responsibility of communication to hearing-impaired students who must adapt to the variation in communication behaviors displayed by each of their teachers. The paper advocates use of a model communication and language policy designed to…
