Teaching Children with Autism to Identify Known and Unknown Information across Self and Others.

This study evaluated procedures for teaching three children diagnosed with autism spectrum disorder the perspective-taking skill of identifying known and unknown information by others based on what they were sensing across all five senses: see, taste, feel, hear, and smell. Using a multiple baseline across participants design, this study evaluated a training package consisting of rules, multiple exemplar training, error correction, and reinforcement. The treatment package successfully taught participants to identify known/unknown information based on what individuals sensed. Generalization across untrained stimuli and people was observed from baseline to posttraining for all participants.
