5-Trial Adjusting Delay Discounting Task
A brief, 5-question delay discounting task that takes under a minute to administer designed by Koffarnus, Warren, and Bickel (2014).
Delay and Probability Discounting Procedure (random adjustment)
The Delay Discounting Task developed by Richards, Zhang, Mitchell, and De Wit (1999). The procedure uses a random adjustment algorithm to produce discount estimates (i.e., indifference points) for 10 different delays.
Delay Discounting Task - ABCD Consortium
An adaptation of the delay discounting task for adolescents used in the ABCD Consortium's longitudinal study on cognitive development from childhood to early adulthood.
Delay Discounting Task - ABCD Consortium - Smart Phone
An adaptation of the delay discounting task for adolescents used in the ABCD Consortium's longitudinal study on cognitive development from childhood to early adulthood.
Delay Discounting Task - ABCD Consortium - Tablet
An adaptation of the delay discounting task for adolescents used in the ABCD Consortium's longitudinal study on cognitive development from childhood to early adulthood.
Delay Discounting Task (short term)
The Delay Discounting Task developed by Cherek, Moeller, Dougherty, and Rhoades (1997). The task provides a measure of impulsivity by evaluating discount rates for rewards delayed by 10 seconds.
Delay Discounting Task with Money and Food
The Delay Discounting Task involving money and food. The task modeled off of the task used by Odum, Baumann, and Rimington (2006) and in developmenet by Leonard Epstein et al (2010).
Experiential Discounting Task
Then Experiential Delay Discounting Task used by Reynolds & Schiffbauer (2004) to measure value assigned by a participant to experienced delays.
