The evidence base for relational frame theory.
Relational frame theory (RFT) is a contemporary account dealing with language and cognitition from a behavior analytic perspective. RFT has been debated and has created some controversy, especially concurring the empirical evidence for the theory.
The empirical base has been and still is expanding and Simon Dymond, Richard J. May, Anita Munnelly and Alice E. Hoon has taken on the task of examining the evidence base. They have summarized their findings in an article published in The Behavior Analyst (2010). They found that between 1991 and 2008 there was published 62 empirical articles on RFT, mostly with adults and the relational frame of sameness.
For those interested in RFT, this article gives å nice summary of the evidence base, and should be examined for further information.
