Research Interests

I am intrigued with applying concepts and procedures from behavioral economics to better understand human choice and behavioral decision making. With my colleagues and students, I conduct studies on temporal and probability discounting processes. The goals of this research are to (a) determine how these processes are affected by experimental manipulation (e.g., amount, sign) and (b) describe the quantitative characteristics of the functions that best describe these processes. Ultimately, such work may have implications for the understanding of impulsive and risky behavior.

Some of my other interests include the history, theory, and philosophy of behavior analysis and their relation to other psychological systems.

Service and Professional Interests

I regularly reviews articles for journals devoted to psychology and behavior analysis. I am on the editorial board of The Psychological Record, and have reviewed for numerous other journals, such as The Behavior Analyst, Behavioural Processes, and the Journal of the Experimental Analysis of Behavior. My students and I attend and participate in the annual meetings of the Society for Quantitative Analyses of Behavior, the Association for Behavior Analysis, and the Alabama Association for Behavior Analysis. I am also a program chair for Division 25 of the American Psychological Association.
