BRIAN A. IWATA (University of Florida)
Dr. Brian Iwata received his Ph.D. in Clinical and School Psychology from Florida State University as a student of Jon Bailey. He subsequently held faculty appointments at Western Michigan University and at the Johns Hopkins University School of Medicine, and he is currently Professor of Psychology and Psychiatry at the University of Florida, where he directs research programs on self-injurious behavior, the Prader-Willi syndrome, and autism. Brian’s primary areas of interest are research methodology, developmental disabilities, functional analysis of severe behavior disorders, and program evaluation. He has published over 200 articles and chapters on these topics and has received over $5 million in research grants to support that work. Brian is the former editor of JABA and past president of ABA, APA Division 33, FABA, SABA, and SEAB. He has chaired study sections for both NIH and NIMH and is a fellow in AAMR, ABA, APA, and APS. Brian has received a number of significant awards for his work, including the D.F. Hake Award for Contributions to Basic and Applied Research as well as the Award for Applied Research from APA, the Award for Distinguished Contributions to Service from ABA, and the R. B. Dillard Award for Excellence in Research from AAMR. Brian is just as much a teacher of researchers as he is a researcher: Half of the recipients of the B. F. Skinner Award (APA Division 25) have been his former Ph.D. students.

Extinction is the most direct method for reducing the frequency of behavior. Nevertheless, the procedure is prone to misapplication, may produce undesirable effects, and can be difficult to implement. This presentation will consider some limitations associated with the use of extinction and will suggest alternative strategies.
