- All hypotheses confirmed 
- Children with ADHD have higher delayed discounting than neurotypical peers
- Increased memory load is hard on both kids with ADHD and neurotypical kids. However, performance is harder for kids with ADHD when memory load increases. 
- The study showed that the further away a reward will be received decreases the value that an individual associates with that reward. (Fabio et al., p. 8). 

Discussion - Fabio et al., 2020

- Initially, no effects were found - maximum digit span on primary task results 
- However, in the multivariate ANOVA analysis, memory load and time delay had significant main effect on k, or the rate of delayed discounting. 
- Post-hoc comparison: Memory load had a greater effect for shorter reward delays

Washtenaw Community College

- 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
