This list serves as a forum for scientists, scholars, practitioners, and students to discuss Relational Frame Theory (RFT), an explicitly psychological account of human language and cognition. RFT is an approach designed to be a pragmatically useful analysis of complex human behavior, providing empirical and conceptual tools to conduct an experimental analysis of substantive topics in this arena. It is based on the principles of behavior analysis and contextual behavioral science. RFT is looked to as the conceptual basis for Acceptance and Commitment Therapy, as well as an increasingly large array of other applied interventions such as language training program, or programs designed to develop a sense of self in developmentally delayed children. The list is restricted to those who are professional or student members of the Association for Contextual Behavioral Science (ACBS). The list is owned and managed by ACBS and membership supports the infrastructure to keep it going. So before you join, go join ACBS at www.contextualpsychology.org. This should not be a big barrier since ACBS dues are "values-based" and the amount is up to you (down to $1). You will also need a Yahoo account but that is a formality (they do not spam or sell their lists so it is safe).
