An intertemporal-choice task that measures the degree to which participants prefer smaller immediate rewards over larger delayed ones.
Configure parameters and run an interactive preview exactly as participants will experience it. No data is recorded.

Task parameters
Presents choices between smaller-sooner and larger-later rewards. Outputs: immediate choice proportion and hyperbolic discounting rate (k).
This is a researcher preview. No participant data is recorded.
Simulated participant view
An intertemporal-choice task that measures the degree to which participants prefer smaller immediate rewards over larger delayed ones.
No data is recorded
On each trial two option cards are shown — a smaller amount available today and a larger amount available after a stated delay — and the participant taps their preferred option.
Useful in addiction, impulsivity, self-regulation, health behaviour, and economic decision-making research where delay sensitivity is a target individual-difference variable.
Less suitable when the study requires clinically validated scoring rather than an exploratory hyperbolic-k estimate, or when currency framing may cause disengagement.
Keep amounts realistic and delays varied to spread out choice patterns. Use a minimum of 10–15 trials for a stable k estimate.
The k estimate provided is a simplified single-parameter proxy. For formal k fitting or AUC scoring, export the trial-level choice data and compute offline.
