Comparison of the relative effectiveness of oral and total communication training models for teaching expressive labeling skills to three echolalic autistic children (six-nine years old) demonstrated that total communication was the most successful approach with each of the Ss. (Author/CL)

The study demonstrated the utility of the alternating treatments design in determining the most efficacious language training approach with mentally retarded children. Oral communication, total communication, and modified total communication were each used with two children in three trials. The preferred approach was consistent within each subject…

The effectiveness of verbal, sign, and simultaneous systems for the acquisition of receptive language by an autistic boy was investigated. Results suggest nonsignificant differences among the three methods. (Author/SEW)

Five children with severe educational retardation, aged 5-12, were involved in sign training in which the spoken words corresponding to signs were receptively known to participants. Whether signs were taught concurrently or in a serial fashion, signs taught by total communication were acquired faster than those taught by sign-alone training.…

Total communication procedures were used with three severely mentally retarded children (mental ages 2 to 4) to examine the effects of receptive speech on the acquisition and maintenance of manual signing. Signs corresponding to known words were generally acquired faster and retained better than signs corresponding to unknown words. (Author/JW)

The relative effectiveness of total communication and oral communication training in a parent-assisted, home-based language intervention program was studied with 15 Down's syndrome children, 18-36 months old. (Author/SEW)
