Invited Tutorial #21
CE Offered: PSY/BACB
SQAB Tutorial: Domain Effects, Obesity, and Delay Discounting
Saturday, May 27, 2017
10:00 AM–10:50 AM
Hyatt Regency, Centennial Ballroom D
Area: EAB; Domain: Basic Research
PSY/BACB CE Offered. CE Instructor: Erin B. Rasmussen, Ph.D.
Chair: Steven R. Lawyer (Idaho State University)
Presenting Authors: : ERIN B. RASMUSSEN (Idaho State University)

Delay discounting refers to a preference for smaller, sooner over larger, delayed outcome. Domain effects refer to a tendency for some outcomes to be more strongly discounted than others. We will review research that reports domain effects across a variety of special populations, but focus on an outcome that is one of the most steeply discounted food. Our laboratory, which examines delay discounting with obese rats and humans has uncovered a consistent pattern of domain-specific discounting effects with food as the outcome. In other words, the largest differences in obese and healthy-weight subjects tend to be with food or food-related outcomes. This domain-specific finding also has been shown in response to the treatment of mindful eating. Implications for using multiple relevant outcomes in discounting studies will be discussed. This presentation will also serve as an introduction to a panel discussion on the application of behavioral economics to obesity.

Instruction Level: Intermediate
Target Audience:

Certified behavior analysts, licensed psychologists, graduate students.

Learning Objectives: At the conclusion of the event, the participant will be able to: (1) describe delay discounting and how it is measured; (2) state what a domain effect is and give an example of food as a domain-specific outcome; (3) describe how domain effects have been found in obesity and with mindful eating as a treatment.
ERIN B. RASMUSSEN (Idaho State University)
Erin Rasmussen received her Ph.D. from Auburn University in the Experimental Analysis of Behavior with an emphasis in behavioral toxicology and pharmacology, under the direction of Dr. Chris Newland. She is currently a Professor of Psychology at Idaho State University. In her twelve years at ISU, she helped build a new Ph.D. program in Experimental Psychology. She conducts translational research on the behavioral economics of obesity using humans and animal models. Her recent work has been published in such journals as Physiology and Behavior, Experimental and Clinical Psychopharmacology, Behavioral Brain Research, Behavioral Pharmacology, Behavioural Processes, Behaviour Research & Therapy, Psychopharmacology, Appetite, and Health Psychology. She was recently awarded a three-year research grant from the National Institutes of Health to investigate delay discounting and obesity in food-insecure women. She currently serves as Associate Editor of The Behavior Analyst and just finished a term on the ABAI Science Board. She also served as past-president of Four Corners Association for Behavior Analysis and as the program chair for the Southeastern Association for Behavior Analysis.
