Thanks. I'll have a look at Cambridge Brain Science. I saw that Posit was developing software for sz. I was pretty excited by that. I own one of their software programs which is designed to sharpen up auditory processing, but it's mainly aimed at older people. I don't think my son has those kinds of issues. Actually, though, since it allows two people to use it, I could have him try it. I just don't want to annoy him by pushing something useless on him.
