"Since RFT first appeared in the experimental literature, it has been hailed as a breakthrough in our scientific understanding of language and cognition with direct and important implications for clinical psychological practice. Yet, descriptions of RFT, written largely for technical audiences, have been, at best, curiously baffling, and at worst, maddeningly incomprehensible. In this book, Törneke has solved the puzzle of RFT! He summarizes the history of RFT, its key features, and its clinical implications with language that is user-friendly and easily understandable. I believe this book will make a huge difference for clinicians who wish to understand RFT and its implications for clinical practice. It also may be a useful learning tool for researchers and RFT experts themselves who wish to learn and see a beautiful example of how RFT can be presented clearly and comprehensively."

"For years, clinicians have asked me for recommendations about what they should read to learn RFT. There was really no good advice I could give except ‘be persistent.’ Finally, I have a better answer. If you want to understand relational frame theory, this is the place to start. Törneke’s RFT primer is both masterful and accessible."

"At times, while reading Törneke’s book, I have felt as though I were in the middle of a thriller about the psychopathological behaviors of humans. Clues to unraveling the mystery embedded in complex concepts like ‘arbitrarily applicable relational responding’ have alerted me, as the reader, to what is coming up next. Our ability for relational framing and for rule-governed behavior may at first glance seem fabulous—a gift from the gods—but darkness lurks around the corner. Our ability to problem-solve is the villain. This book helps me make sense of it all."

"Until now, explanations of relational frame theory have remained largely esoteric and even impenetrable to all but the most specialized scholars. For the first time, this extraordinary book provides a highly accessible account of relational frame theory, including its larger context within psychology, the current research in the field, and its many potential applications. Törneke strikes a fine balance between doing justice to relational frame theory and making the theory, research, and its implications readily comprehensible to the non-expert. This unique book is a must-read for scholars of human cognition, as well as clinicians, educators, others seeking to harness the power of basic psychological principles in their applied work, and anyone interested in the renaissance of modern behavior analysis."

—James D. Herbert, PhD, professor of psychology at Drexel University in Philadelphia, PA, and director of Anxiety Treatment and Research

"On rare occasions, the skills of writer, therapist, and theorist combine to give the field a sophisticated yet highly practical book. This much-awaited translation shows relational frame theory as an accessible, powerful tool for all who use talk therapy. A must-read for those interested in contemporary behaviorism."
