Language just gradually came in, one or two stressed words a time. Before then, I would just scream. I couldn't talk. I couldn't get my words out. So the only way I could tell someone what I wanted was to scream. If I didn't want to wear a hat, the only way I knew to communicate was screaming and throwing it on the floor.
Temple GrandinBy looking at autistic kids, you can't tell when you're working with them who you're going to pull out, who is going to become verbal and who's not. And there seem to be certain kids who, as they learn more and more, they get less autistic acting, and they learn social skills enough so that they can turn out socially normal.
