Abstract
Dysfunctional control exerted by reason-giving in adult psychopathology is interpreted from a radical behavioral perspective. Verbal-social contingencies which support the establishment of reason-giving and its control over maladaptive actions are reviewed. A contextual approach to psychotherapy, comprehensive distancing, which attempts to weaken dysfunctional verbal control is described briefly. Data relevant to therapeutic process are presented. The overall results suggest that comprehensive distancing facilitates therapeutic change through a process consistent with a behavioral analysis of reason-giving. Suggestions for further research and radical behavioral approaches to psychotherapy are discussed.
