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)

This review of research discusses how children with autism may acquire equivalence classes after learning to supply a common oral name to each stimulus in a potential class. A proposed methodology for researching referent naming and class formation, analysis of stimulus classes, and generalization is offered. (CR)

A time delay procedure was used to teach three children (ages 5-9) with autism to ask the question "What's that?" when novel stimuli were presented, and generalization of the skill was assessed. Results suggest that children with autism can be taught to ask questions that lead to acquisition of new information. (Author/DB)

This study found that naturalistic conversation training improved the spontaneous speech production of two children (ages three and four) with speech production disabilities. (Author/DB)
