A six-year-old nonvocal girl with autism who had acquired a variety of signs and imitative responses consistently failed to acquire a tact (labeling) repertoire. When procedures to transfer stimulus control from verbal to nonverbal stimuli were implemented, the subject quickly learned to tact all 18 target stimuli. (Author/DB)

Four nonverbal autistic children (10-15 years old) were taught expressive sign labels for common objects, using a training procedure that consisted of prompting, fading, and stimulus rotation. (Author/BD)

Total communication procedures were used with three severely mentally retarded children (mental ages 2 to 4) to examine the effects of receptive speech on the acquisition and maintenance of manual signing. Signs corresponding to known words were generally acquired faster and retained better than signs corresponding to unknown words. (Author/JW)

Senior drivers are vulnerable to automobile crashes and subsequent injury and death. Safety belts reduce health risks associated with auto crashes. Therefore, it is important to encourage senior drivers to wear safety belts while driving. Using a repeated baseline design (AAB), we previously reported that motivating signs boosted safety belt usage…

A program was implemented to increase the manual signing of five profoundly retarded (mean age, 19 years) and four autistic (mean age, 9 years) youth within their daily environment. (Author)

A study of three adults with profound mental retardation examined the effectiveness of functional communication training in reducing self-injurious behavior (SIB) and in shaping an alternative (communicative) response while SIB continued to be reinforced. Results found when extinction was added to the training procedure, SIB decreased and manual…

Illegal parking in spaces reserved for people with physical disabilities was examined across three conditions: a vertical sign alone or in combination with a message sign announcing public surveillance or a message device dispensing reminder notes and announcing community involvement. Messages increasing expectation of negative social consequences…
