- Replication of Hinson, Jameson, & Whitney, 2003- association between executive control system and impulsivity 
- Participants included 30 kids with ADHD, confirmed through teacher observation and rating, IQ tests, and psychologists' confirmation. 
- Researchers measured participants' digit span to distract them from the main task of delayed discounting - hypothetical money task
- Participants chose to collect less money during the same day or to collect more money later 
- Participants completed 16 trials 

The Present Study: Fabio et al., 2020

- Both children and adults with ADHD have higher rates of delayed discounting than neurotypical people
- Decisionmaking is more of a struggle for ADHDers

Washtenaw Community College

- Higher delayed discounting when willing to decline greater rewards available in the near future; preference for smaller awards available immediately
- Relationship to executive function - neurotypical= lower delayed discounting - easier to wait for larger rewards for the near future 
- ADHD: higher delayed discounting - impulse control is hard
