It is part of the library series that has been created for the many people interested in the field of autism spectrum disorders who want up-to-date, authoritative informa- tion without having to locate and read through the original sources. Our goal in this series is to review, synthesize, and organize the infor- mation so that it can be presented comprehensively and clearly. This volume is the culmination of over a decade of clinical work identifying, organizing, writing, and editing the most current informa- tion available about this high functioning group of people with autism spectrum disorders from current reputable sources. The book explores the history and emphasizes the diagnosis, assessment, and treatment of these people and their families. We hope that we have done justice to this extensive literature so that it can be of use to these people them- selves as well as to their many friends,colleagues, and families, and to the interested citizens who are seeking more information about this intriguing area of inquiry. V Acknowledgments We are indebted to many people for their help on this project, and we want to acknowledge their substantial contributions. First and foremost we want to thank our TEACCH colleagues and the many families and professionals who have worked with us. Their interest in our views, perceptive comments about HFA/AS, their support, and their assistance have been invaluable. There are many exciting and rewarding aspects of living and working in North Carolina, but most important are the terrific people we meet and work with. Joan Berry has been particularly important throughout this pro- ject, typing numerous drafts, changes, corrections, and insertions. She has done all of this work with a smile on her face and her usual accu- racy and efficiency. Leia Grossman, a student research assistant, did many of the mundane tasks that are so essential for an accurate and comprehensive final product. Her assistance in tracking down and checking references has added immeasurably to this final product. Finally, as with all our projects collaborating with Kluwer, our editor, Mariclaire Cloutier, has to be thanked for her responsiveness, assistance, and all-around excellence. Her patience as we wrote and rewrote the final drafts is especially appreciated. Finally, our friends, families, and colleagues are to be thanked for enduring our absence as we worked the demanding schedule that a project like this requires. Their interest and understanding made all of this bearable, even during the most intense periods of working on this manuscript. Special thanks are due to Joan Goodrich Lang for her ongoing interest and support. vii Contents 1.
