Odum, Amy – Delay Discounting: Who, What, When, Where, Why, and How? - Delay discounting is the decrease in the present value of an outcome when its receipt is remote in time. Many problematic behaviors (e.g., drug action, obesity, gambling) can be conceptualized as problems of extreme delay discounting. Delay discounting has been extensively studied in humans and non-humans, using a variety of procedures, populations, and outcome types. Most (but as yet not all) of the basic findings in the area have been substantial generally across these features. In this tutorial I will describe how to conduct research in delay discounting. I will give examples of illustrative procedures to measure delay discounting and evaluate their unity in different research situations. I will then provide a step-by-step description of how to use quantitative modeling to analyze the resulting data. I will explain different models and their strengths and weaknesses. Finally, I will provide a summary of major finding in the literature and possible future directions for the feild.
