Thanks everyone for your questions to Dr. Steven Gutstein, developer of RDI, and Carol Gray, developer of Social Stories (tm). I am now working with the staff at RDI to develop an article that also answers some of your specific questions. I've also sent Carol Gray your questions, and anticipate chatting with her in the next few weeks. Keep checking back here over the next few weeks; I expect to have articles on both topics posted on the site before the July 4th weekend!
