As before, I’ve included new research that has been published since the previous edition. Most of the new studies have been in the areas of (1) constitutional factors and (2) developmental, environmental, and learning factors. To make this dense material more digestible, I’ve divided each of these areas into a chapter that gives a broad overview of the research and a chapter that gives the fine details. The chapters on assessment and treatment have been updated as new material has become available and as I’ve gained a better understanding of how to assess and treat clients. I think the chapters on treating school-age children and on treating adolescents and adults are most different from those in the previous edition. My clinical experiences in these intervening seven years have given me a better sense of how to sequence treatment and what are crucial experiences for clients. Finally, I have provided some video clips online at LWW’s thePoint to illustrate our work with a variety of clients. These, along with new test material and PowerPoint slides, will make this a more complete text from which to teach. Comments on the last edition—from students, clinicians, and instructors—have made this edition better. I look forward to hearing how it works for you. — Barry Guitar 8 ACKNOWLEDGMENTS Many people have made this book a pleasure to write, especially the individuals who stutter and the students who have worked with me over the span of 40-something years. I would also like to thank my publisher, Lippincott Williams & Wilkins, who took a big chance on me and this text more than 20 years ago. One of their fine staff members, Staci Wolfson, has managed this project from beginning to end, with encouragement, direction, gentle prodding, and tact. I am most grateful to her. In addition, I appreciate the support from Mike Nobel, acquisitions editor; Shauna Kelley, marketing manager; Jen Clements, art director; and Bot Roda, the artist whose fine work you see throughout the book. As with earlier editions, Rebecca McCauley and Charles Barasch have contributed immensely to this text in many ways, from editing my chaotic writing to suggesting drawings and ancillary material to providing organizational ideas. I am indeed obliged to them. Finally, I wish to thank my wife, Carroll, who has listened patiently to my endless talk of stuttering and who has also carefully edited every page and chased down every reference, in addition to giving great help with the video clips. This edition is dedicated to Cully Gage and the memory of Charles Van Riper. 9 10
