Document Summary
10 changing the stimulus control of a behaviour with fading (part 2) Peter is diagnosed with autism and he possessed an extensive vocal mimicking repertoire. He could repeat words other people said but had little other verbal behavior. When asked what is your name, he said name or repeated the question: problem of stimulus control: questions evoked mimicking responses. Veronica taught peter to respond to what is your name. Because peter had been taught to work for tokens (poker chips) that could be exchanged for treats, she decided to use tokens are reinforcers. In a soft whisper she asked him what is your name. Then loudly, before peter responded, she shouted peter. Then peter mimicked peter, and veronica reinforced this with good boy and a token. Over several trials, she asked the question loudly and said the answer softly. On each trial, she continued to reinforcer peter.
