Temporal discounting rate - large stakes is a measure of the tendency to discount future rewards and take an immediate but smaller payoff over waiting for a later but larger one. Temporal discounting tendency was estimated for both large and small stakes--this is the large stakes variable (i.e., the questions refer to larger amounts of money). The current payment is fixed at $1000 and the delay period is fixed at one year for all questions. Higher score means a participant is less likely to wait for a later but larger reward.

To estimate the subject specific discounting rate, we use a well-established hyperbolic function based on the odds of choosing the delayed reward over the immediate reward at different values. See reference for details.

Participants are asked the following questions:

1. $1200
2. $1100
3. $2200
