We recently had our son tested, and the tests were very helpful. What was more surprising is that the psychologist's evaluation/assessment seems to fit one of the types perfectly. We have already adjusted our approach signicantly, with results already apparent. What we thought was a stubborn, rude beligerant little boy, is actually a very sensitive feeler, who is actually very remorseful over innocent mistakes. By reading this book, parents may become more aware that what appears to be ADD, or a learning disability may be a minority personality type, or a child trying to "live out of type". It is fascinating to learn that a lot of your child's supposedly weird charecteristics are actually normal for him, and that he may just march to the tune of a different drummer.
