A large number of people helped me to write this book. Special thanks must go to my editor Peter Robinson who patiently read every word more than once, invariably gave good advice, and never failed in his good humour and encouragement. Other people also read draft chapters and boosted my confidence as well as pointing out my failings: John Skelton, Ruth Sage, Sarah Lewis, Mark Holloway, Steve Fisher, two anonymous reviewers, and the entire classes of 1999/2000 MSc students endured at least some of my earlier efforts. (Of course any deficiencies are still my own.)
My students were also a source of inspiration as well as guinea-pigs-virtually everything in this book has been presented to or tried out on them-which probably explains why one reviewer wrote, "You can imagine the author delivering this material in a lecture theatre." I also thank my doctoral students, in particular, Andrew Day, Guy Lubitsh, Georgina Slaven, and Mike Rugg-Gunn for the many insights their "real world" practitioner research provoked. Caroline Osborne, Lucy Farr, Susan Rudkin, Kathryn Russel, and the staff of Psychology Press, were very supportive.
Lastly I must thank my son Thomas for his patience in putting up with the book writing in addition to my full-time job and long-distance commuting. It's a wonder he got any attention from me for the past 2-3 years!
