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)

Four autistic children, age 8-15, exhibited fewer correct responses to a stimulus as the number of stimulus components was increased from 1 to 4. Training was effective in producing some generalized increases in responses to complex stimuli. (Author/JDD)

Two methods of prompting were compared for their relative effectiveness in teaching a group of autistic students, age 12-20, to discriminate line drawings used in picture communication books. Students required fewer trials to criterion and made significantly fewer errors in the delayed-prompting technique compared to the fading-of-prompts design.…

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)

Eleven autistic children, age 8-19, were administered a variation of the Stroop task which involved comprehending single words that differed along a concrete-abstract dimension and that exhibited varying amounts of interference. Both concrete and abstract words appeared as meaningful to autistic children as to reading-matched controls. (Author/JDD)

Twenty-three autistic children (age 4-19) and 23 mental age-matched controls completed a task of sustained attention. Results suggest that autistic children's difficulties in sustaining attention may be attributable to developmental delay and motivational contingencies of task rather than to a primary impairment in ability to sustain attention.…
