This paper compares explicit instruction in second-language Spanish with a control treatment on a written picture description task and a timed auditory grammaticality judgment task. Participants came from two intact, third-year US high school classes, with one experiencing a week of communicative lessons on the Spanish clitic "se"…

This study evaluated the acquisition of incidental and observational information presented to 6 children with autism in a small group instructional arrangement using a constant time delay (CTD) procedure. A multiple probe design across behaviors, replicated across 6 participants, was used to evaluate the effectiveness of the CTD procedure and to…

Children with autism often have difficulty successfully applying newly acquired skills to novel situations. Naturalistic teaching procedures have been developed to help address this problem with generalization. These naturalistic procedures promote generalization through the use of natural consequences, diverse training, and the incorporation of…

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…

Incidental teaching procedures were used to train a 16-year-old mildly handicapped student to use social amenities in a resource classroom. Generalization to another resource room and an art classroom was assessed. Results indicated increased use of social amenities in the training setting and generalization settings. (Author/PB)

This study assessed effects of a procedure to train two therapists and a college intern in the techniques of incidental teaching. Training took place in a community-based group home serving five autistic children. The training procedure promoted generalization of skills across materials, settings, children, and group size.

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…

Three typical preschoolers were trained as peer tutors for three young children with autism. Tutors used incidental teaching to obtain verbal labels of preferred toys by children with autism. Adult supervision and assistance were faded systematically with resulting maintenance of increased reciprocal interactions. (Author/JDD)

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.…

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…
