I have an autism class. As you all know one of the biggest problems for those kids is to communicate. One of my students has the least desire to initiate communication. It's always, "Show me what you want", and stuff like that. A lot of prompting. This kid is 10 y.o., definitely has major developmental delays, and no intent to communicate. Oh yeah, he is also non-verbal. He is at the presymbolic stage, slowly moving to a symbolic stage, but he does not understand abstract pictures yet. We use photographs with him, because that's what he understands. Anyways, can you give me any suggestions on how to teach him to initiate communication. I know at home his parents do not encourage him to communicate. His mom says she knows exactly what he wants, plus everything is usually easily accessible at home, so he can just get what he wants. She told me she tried using pictures/icons with him, but he just stims off them, playing with velcro etc. If you guys also know of a good website or a book that explains in details the stages of PECS, I would appreciate any advice. Thanks!
