Three language-delayed autistic children (6-11 years old) were taught expressive use of prepositions to describe the location of preferred edibles and toys. Traditional highly structured training and incidental teaching procedures were used in a classroom setting, and generalization was assessed during free-play sessions. Results clearly indicated…

A review of research on language handicapped, disadvantaged, and other children, indicates that incidental language teaching (natural unstructured interactions between adults and children and which allow adults to transmit new information and give children practice in developing communication skills) is a promising language intervention technique…

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…

This study, involving two three-year-olds with mild mental retardation, found that milieu language intervention can directly enhance the acquisition and generative use of lexical and semantic forms used for varied pragmatic functions and that adult systematic commenting and child spontaneous imitation may interact to facilitate the teaching…

The effectiveness of training mothers to use four incidental language teaching procedures with their language-delayed preschoolers was evaluated. Six mothers were trained to use the following techniques: first, the Model Procedure, which provides the response for the child to imitate; second, the Mand-Model Procedure, which elicits information the…

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…

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…

Delays in language acquisition can have serious deleterious effects on the education and social development of children. A number of related language intervention procedures have been developed for use in natural settings. These procedures include incidental teaching, modeling, manding, time-delay, and milieu language teaching. The present paper…
