Fran,
You recently shared with us Nancy Perry- executive functions and Autism - looking forward for the next instalment . My initial reaction to the article is that the prensence of the therapist , the structure and rewards did manage to get her initially interested in cooperating. In the longer term she will need help in aquiring skills like executive functions etc to sustain the progress, she is staring to lose interest in the rewards and not developing any intrinsic motivation and self pride , intrinsic reward in the things she does. Most parents can't reproduce the structure of a Residential Treatment Center (RTC) or maintain the same atmosphere that existed when the therapist was in.
