A study of five autistic children in a segregated preschool, five mainstreamed autistic children, and four nonhandicapped, integrated peers found that all of the groups made better than normative progress in language development. There were no significant differences in changes in language ability between segregated and mainstreamed autistic…

Six autistic children, age 3-6, and 6 children with Down syndrome were followed over a period of 12-26 months. Autistic children followed the same general developmental path as the Down syndrome children in the acquisition of grammatical and lexical aspects of language. (Author/JDD)

Preschool children with autism (n=9) and their normally developing peers (n=9) were compared before and after one school year. The autistic children had narrowed the gap after treatment--making a nearly 19-point increase in intelligence quotient and an 8-point gain in language quotient. Results support the value of a language enriched early…

Compared to age-matched and language-matched controls, 15 autistic children (mean age of 45 months) who were administered the Early Social-Communication Scales displayed deficits in gestural joint attention skills in 2 testing sessions 13 months apart. The measure of gestural nonverbal joint attention predicted language development in subjects.…

The authors review research on attempts to promote speech acquisition in severely handicapped students. Studies on verbal imitation, syntactic forms, and semantics are summarized. Implications for instruction are noted, including careful selection of responses likely to occur in the child's normal environment and which have intrinsic reinforcing…

The study compared the attention-directing behaviors of 15 autistic children, 14 children with developmental language delay, and 13 young normal children. Although the autistic children's behavior was most unlike that of the other groups, autistic children did not produce more attention-directing behavior when a high degree of adult direction was…

Sensorimotor functioning in 10 autistic children, age 3-7, was assessed on object permanence, means-end, causality, vocal and gestural imitation, the construction of objects in space, and schemes for relating objects. The number and diversity of pragmatic functions in the children's communication were also analyzed and related to sensorimotor…

Two mentally retarded boys with autism and one girl with Down syndrome were successfully taught to initiate and play a ball game with an adult. The program targeted both nonverbal responses (such as ball contact and cooperative play) and verbal responses for play initiation and compliment delivery. (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…
