Task Presenting Modes, Mathematical Models, and Measures in Delay Discounting
摘要
Abstract
Delay discounting refers to the tendency to discount the subjective value of future reward as a function of the delay to receiving them. Researchers usually use hypothetical money choice task to ask subjects to make choices between smaller-sooner rewards and larger-later rewards. Experiment task can be presented via the mode of computer, index card, and questionnaire. The mathematical models include one-parameter model and two-parameter model. Discounting rate (k), area-under-the-curve (AUC), and ED50 are used to measure delay discounting. Future research should focus on the utility of two-parameter models, measurement indicators, and applicability of the one-shot delay discounting measure.关键词
