Observational learning and children with autism: discrimination training of known and unknown stimuli.

We extended past observational learning research by incorporating stimuli already known to participants into training. We used a multiple-baseline design across three participants to determine the effects of discrimination training on the discrimination of consequences applied to modeled responses using both known and unknown pictures. During baseline, participants were exposed to modeled correct and incorrect picture labels and were observed to imitate modeled responses that were incorrect and followed by negative feedback.
