A sensory extinction procedure (white noise programed through earphones) substantially reduced the stereotypic vocalization of two autistic children (9 years old) but had little practical effect on the clapping and object-dropping responses. (Author/CL)

The study compared the effectiveness and efficiency of constant time delay and system of least prompts in teaching two eight-year-old students with autism to name numerals. Results indicated that both procedures were effective but the constant time-delay procedure was more efficient with these two subjects. (Author/DB)

Signs were used successfully with a blind 10-year-old autistic girl. After eight months of training, she was able to acquire a functional sign vocabulary relying primarily on the tactile-kinesthetic and the auditory modalities. This newly acquired skill had a beneficial impact on the child's general functioning. (Author)

This study assessed effects of teaching sociodramatic play skills to three children (ages five to nine) with autism. Positive changes were observed in play, language, and social skills. These changes generalized across toys and settings, although little generalization to other play partners occurred. (Author/DB)
