Incidental teaching and traditional discrete-trial procedures were used to teach two children (ages 10 and 12) with autism the expressive use of two color adjectives. Results demonstrated that traditional discrete-trial teaching was more efficient and produced faster acquisition but incidental teaching resulted in greater generalization and equal…

A peer-delivered incidental teaching procedure was used to instruct appropriate requesting in three adults with moderate/severe mental retardation or autism during lunch-preparation sessions. The procedure proved to be effective in increasing appropriate requesting. Generalization was obtained, and increased interaction between the residents was…

This study investigated the effectiveness of teacher-implemented naturalistic language intervention within play activities for four elementary students with moderate mental disabilities. While students showed significant increases in numbers of spontaneous language targets used during the intervention condition, they demonstrated minimal…

An instructional procedure to teach laundry skills to four high school students with moderate mental disabilities utilized least prompts with multiple exemplars of materials to facilitate generalization of skills across community settings and multiple exemplars of nontargeted information presented as instructive feedback. Students acquired and…

The effects of analog language teaching and natural language teaching on language generalization and long-term retention in 23 adults with autism and severe/profound mental retardation were examined. Natural language teaching was found to have many strengths and few drawbacks and to produce equal generalization and retention under conditions…

Five children (27 to 47 months old) with mild to borderline levels of mental retardation were given a milieu language intervention program of 3 or 4 small group training sessions weekly. Results indicated the training had a clear facilitative effect on the acquisition and generalized use of common nouns and verbs by four of the subjects.…

Four adolescents with moderate mental disabilities were taught by peers to read key words from labels of cooking products using constant time delay. Students mastered the reading of target key words in a relatively short amount of time with minimal errors, acquired some incidental learning of cooking definitions, and were able to generalize the…
