- Participants chose between less money the same day vs. more money in a later day 
- Rewards: €1–€11, €2–€12, €3–€13 and €4–€14,
- Time delays: 1 week, 1 month, 6 months and 1 year

Delayed Reward Task 

- Random number sequence- participants listened and recited the numbers that they heard to find their digit span 
- 3 conditions- full load, half load, and zero load
- Full load- maximum digit span - 1 
- Half load- dependent on whether the maximum digit span was even or odd; if even, maximum digit span/2. If odd, maximum digit span-1 divided by 2 
- Interference and attention to the primary task: Tried to balance participants' cognitive load through increasing the load on working memory
