ROUTIER, Cédric P.. Relational frame theory (R.F.T.) and acceptance and commitment therapy (A.C.T.): emperor's tailors or knights of the holy Grail?. Acta comport. [online]. 2007, vol.15, n.spe, pp. 45-69. ISSN 0188-8145.

Relational Frame Theory (Hayes, Barnes-Holmes et Roche, 2001) and Acceptance and Commitment Therapy (Hayes, Strosahl et Wilson, 1999) are the two sides of a récent proposition about human language and cognïtion analysis: Relational Frame Theory analyses and explains the phenomena of interest on a theoretical ground, offering a framework to Acceptance and Commitment Therapy, the clinical side, and thus affording it to better develop its practîcal implications. The authors insist both on their neobehaviorist roots, inspired as they are by Kantor and Skinner, and on their ability to cope with areas that were previously investigated mostly by cognitivists models: we question the legitimacy of some of their claims. We evoke their insistence on the rôle of context, a feature similar to others authors that consider communication as a process too. We also underline that Hayes and colleagues are nevertheless strong proponents of some main principles of behavior analysis. We conclude by mentioning the promises but aiso the dangers of the authors' conceptual choices, and use two metaphoric taies (Andersen's Emperor's New Suit and that of the famous Knights of the Holy Grail) to illustrate some of our gênerai conclusions.
