- Memory Load (Zero load, half load, full load) - measured via participants' digit span 
- Time delays (1 week, 1 month, 6 months, 1 year) 
- Various monetary rewards: €1–€11, €2–€12,
€3–€13 and €4–€14

Conditions of the Experiment- Fabio et al., 2020 

- Researchers utilized the Concepts of Time and Money Questionnaire (CTMQ) to make sure participants understood the directions of the task 
- Time, space, and money can be difficult to understand for ADHDers
- First study to assess working memory simultaneously with delayed discounting in kids with ADHD

How did this study differ from previous studies?

- Preliminary Working Memory Task 
- Delayed Reward Task 

Tasks Involved Within the Study 

- 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
