A stimulus in need of a response: A review of relational frame theory: A post-skinnerian account of human language and cognition.

In this commentary, I describe relational frame theory (RFT) as an analysis of complex human behavior that has been insufficiently addressed within contemporary behavior analysis. The theory is described as having an exceptionally ambitious vision of the type that will render behavior analytic accounts more generally acceptable within the broader behavioral and cognitive sciences. In my own view, inductive empirically-driven analyses derived from current data on relational learning (including my own) have not been comparably ambitious; they have not addressed the full range of phenomena to which they might be profitably applied. By contrast, researchers in the RFT tradition have ambitious; they have not addressed the full range of phenomena to which they might be profitably applied. By contrast, researchers in the RFT tradition have tended to project their analyses to encompass a variety of plausible, attractive applications that are arguably within the reach of their current data or data that may be reasonably anticipated in the future. In order for RFT researchers to have its maximum impact, however, I suggest that certain critical steps must be accomplished. First, the theory must be reconciled with the basic behavioral processes that are the core of the experimental analysis of behavior. Second, certain experiments must be conducted that have thus far not been emphasized in the RFT tradition. In particular, I suggest that the current practice of studying college students and verbal school-aged children must be supplemented with comparably intensive studies of populations with developmental limitations (e.g., typically developing children who are just acquiring language). Absent such experimentation, it seems likely that RFT will remain a plausible account that merely competes with other plausible accounts without promoting ultimate resolution of the critical issues.
