I pulled the Early Start Denver Model book down and started reading it. One of the authors spent a bunch of time at UW -- do any of my regular readers know Geraldine Dawson? Of course it was inevitable that Lovaas' name would appear in the acknowledgments but I sort of wish it had not (<-- bad news). Luckily, the authors had made up for it by page 2, when they start by describing how Piaget was wrong-wrong-wrong and here's what the science says currently. (<-- good news) Piaget drives me utterly nuts; it's just tough for me to believe he ever spent any time around children, or really had any understanding of the physical world, either.
I am cautiously feeling optimistic about this book, even if their numbered lists of Why ESDM is Better than RDI or DIR or SCERTS strike me as, um, self-serving.
