T. V. Joe Layng is a Fellow of the Association for Behavior Analysis International and was the 2020 recipient of the APA: Division 25 Fred S. Keller Behavioral Education Award. Joe has over 50 years of experience in the experimental and applied analysis of behavior with a particular focus on the design of teaching/learning environments. He earned a Ph.D. in Behavioral Sciences (biopsychology) at the University of Chicago. At Chicago, working with pigeons, he investigated animal models of psychopathology, specifically the recurrence of pathological patterns (head-banging) as a function of normal behavioral processes. Also working with pigeons, Joe collaborated with Paul Andronis and Israel Goldiamond on investigating the production of untrained recombinant, complex symbolic repertoires in pigeons from simpler behavioral components, a process they described as contingency adduction. Joe has extensive clinical behavior analysis experience with a focus on ambulatory schizophrenia, especially the systemic as well as topical treatment of delusional speech and hallucinatory behavior. In 1984 he founded Enabling Technologies, a software firm which was one of the first to use gamification to teach business software, as well as an array of business products and advanced 3D modeling software. In the 1990s, Joe was Director of Academic Support and then Dean at Malcolm X College in Chicago where he founded the award winning Personalized Curriculum Institute. In 1999, he co-founded Headsprout where Joe led the scientific team that developed the technology that formed the basis of the company’s patented Early Reading and Reading Comprehension online reading programs used by millions of children, for which he was the chief architect. Joe has spent the last several years mentoring students, and interested investigators and practitioners in nonlinear contingency analysis. He has published over 50 articles or chapters, a range of software applications, coauthored a self-instruction book on Signal Detection Theory for behavior analysts and recently coauthored the book Nonlinear Contingency Analysis: Going Beyond Cognition and Behavior in Clinical Practice. Joe is currently a partner in Generategy, LLC.
