Eric J. Fox, Ph.D.

An Introduction to Relational Frame Theory was written and developed by Dr. Eric J. Fox (Doc Fox), the founder and director of Foxylearning. Doc Fox was a contributing author to the first book-length treatment of Relational Frame Theory (RFT), developed the original Association for Contextual Behavioral Science (ACBS) website (and the RFT and ACT websites that preceded it), was a founding member of the ACBS Board of Directors, and has presented and published on RFT numerous times. He holds a doctorate in Learning & Instructional Technology from Arizona State University and a master’s degree in behavior analysis from the University of Nevada, Reno. He has two decades of experience in instructional design and previously served as a faculty member in the psychology department of Western Michigan University, Dean of Instruction at Saybrook University, Director of Instructional Design for Altius Education, Senior Content Developer at Cengage Learning, and Director of Educational Technology for The Ohio State University College of Medicine. His love of learning, technology, and behavioral science is coupled with an unhealthy affinity for Batman.

Upon completing the tutorial, the learner should be able to:

1. Identify two of the distinguishing characteristics of human language and how they are accounted for by Relational Frame Theory (RFT)
2. Identify definitions and examples of key theoretical concepts in RFT (including derived stimulus relation, functional contextual theory, relational responding, generalized operant, multiple exemplar training, mutual entailment, combinatorial entailment, transformation of stimulus functions, and contextual cues)
3. Specify the process by which relational responding leads to derived stimulus relations
4. Analyze samples of natural language using the terms and concepts of RFT

The tutorial requires only an active internet connection and a relatively modern web browser with JavaScript enabled.

The content of this tutorial should be considered quite accurate, as it was written by an expert in the field and reviewed for accuracy by Dr. Steven C. Hayes, who led the development of RFT and Acceptance and Commitment Therapy (ACT), and Dr. Dermot Barnes-Holmes, who is one of the most prolific RFT researchers and scholars in the world. This tutorial should benefit any psychologist, behavior analyst, student, or behavioral science professional who would like to have a conceptual framework for analyzing human language and cognition that is more functional and pragmatic than the structural analyses of traditional linguistics or cognitive psychology. It will be particularly beneficial to those wishing to understand the theoretical basis of ACT or those working to establish verbal repertoires with children or adults who have language delays. This tutorial will not provide you with training in specific interventions or methods based on RFT, but it will provide you with a conceptual understanding of the theoretical basis of such interventions and methods. There is little to no risk associated with completing this tutorial, aside from the physical risks associated with any computer work (e.g., repetitive stress injuries and eyestrain) and possibly severe boredom.

This tutorial was initially developed as part of the author’s dissertation research at Arizona State University. The topic was selected to introduce the complex concepts of Relational Frame Theory (RFT) to a broad audience. A beta version was introduced in 2003, with the first full release in 2004. The tutorial earned the author the Nova Southeastern Award for Outstanding Practice by a Graduate Student in Instructional Design from the Design & Development division of the Association for Educational Communications & Technology. With an award name that long, you know it’s got to be good. The first commercial version (developed in Adobe Flash) was launched on Foxylearning in January 2010 and the first HTML5 version was launched in May 2012. Significant updates were also released in June 2013, June 2019, and January 2020.
