JOURNAL OF THE EXPERIMENTAL ANALYSIS OF BEHAVIOR 2004, 81, 189±204 NUMBER 2(MARCH) DATA IN SEARCH OF A PRINCIPLE: A REVIEW OF RELATIONAL FRAME THEORY: A POST-SKINNERIAN ACCOUNT OF HUMAN LANGUAGE AND COGNITION DAVID C. PALMER SMITH COLLEGE Responding to derived relations among stimuli and events is the subject of an accelerating research program that represents one of the major behavior analytic approaches to complex behavior. Rela- tional Frame Theory: A Post-Skinnerian Account of Human Language and Cognition (Hayes, Barnes-Holmes, & Roche, 2001) offers a conceptual framework for this work and explores its implications for verbal behavior and a variety of other domains of complex human behavior. The authors dismiss Skinner's interpretation of verbal behavior as unproductive and conceptually ¯awed and suggest a new de®- nition and a new paradigm for the investigation of verbal phenomena. I found the empirical phe- nomena important but the conceptual discussion incomplete. A new principle of behavior is prom- ised, but critical features of this principle are not offered. In the absence of an explicit principle, the theory itself is dif®cult to evaluate. Counterexamples suggest a role for mediating behavior, perhaps covert, thus raising the question whether a new principle is needed at all. The performance of subjects in relational frame experiments may be a mosaic of elementary behavioral units, some of which are verbal. If so, verbal behavior underlies relational behavior; it is not de®ned by it. I defend Skinner's de®nition of verbal behavior and argue that an account of relational behavior must be integrated with Skinner's analysis; it will not replace it. Key words: equivalence classes, de®nition of verbal behavior, private events, relational frame theory, relational frames, verbal behavior Relational frame theory made its debut in requires that, whatever our biases, we weigh 1985 in a paper presented by Steven Hayes it carefully. and Aaron Brownstein at a meeting of the The 13 chapters in the book are separate Association for Behavior Analysis and has fos- papers, written by shifting subsets of the 19 tered considerable empirical work, concep- authors.
