Relational Frame Theory A Post-Skinnerian Account of Human Language and Cognition

"A remarkably brilliant book that integrates some of the main theories of radical behaviorism with cognitive behavioral theories and practices of psychotherapy. This book gives more plausible explanations of why people behave the way that they do, and particularly why they are frequently dysfunctional, than any other I can think of."

(Albert Ellis, Albert Ellis Institute, New York)

"[An] exciting and innovative book. It indicates that a behavioural account can shed light on many more of the complexities of language and cognition than had previously been supposed... it is abundantly clear from this book that the behavioural approach is alive and kicking, and full of vitality."

(W. Eysenck, Royal Holloway University of London)

"This is a truly remarkable book... If Chomsky had seen this work 40 years ago, the history of psychology could have been very different."

(Paul M. Smeets, Leiden University, The Netherlands)

"The book is certainly a tour de force and clearly merits a much wider readership among those interested in empirical and theoretical issues in language and cognition."

(Contemporary Psychology, APA Review of Books, 48:4 (2003)
