Two experiments with a total of 17 adolescents or adults with severe mental retardation evaluated the potential of exclusion procedures (selection of an undefined object in comparison with a defined object) as a means of training basic naming skills. Reliable exclusion and naming performance were demonstrated in nearly all subjects. (DB)

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…

A time delay procedure was used to teach three children (ages 5-9) with autism to ask the question "What's that?" when novel stimuli were presented, and generalization of the skill was assessed. Results suggest that children with autism can be taught to ask questions that lead to acquisition of new information. (Author/DB)

The primary and generalized effects of Enhanced Milieu Training were examined with six preschool children with significant language delays. Children systematically increased their use of target language skills during the intervention sessions, and these changes were maintained when treatment was discontinued. Some generalization to untrained…

Four students (ages seven to nine) with moderate mental retardation were successfully taught to name photographs of foods using a progressive time delay procedure. Presentation of the supermarket grocery department as part of the discriminative stimulus was effective in increasing the percentage of correct responding. Some generalization occurred…

This study found that naturalistic conversation training improved the spontaneous speech production of two children (ages three and four) with speech production disabilities. (Author/DB)

This study evaluated the effectiveness of an innovative treatment sequence designed to facilitate semantic/pragmatic language development in a 5-year old with high-functioning autism. The independent variable was a treatment sequence emphasizing video vignettes and role plays. Dependent variables included efficient gaze, responding without delays,…
