As a measure of impulsivity, the Delay Discounting Task (DD) measures how long the rodent is prepared to wait for a larger reward.
Example Neural Systems Involved
- Dopamine
Clinical Areas Showing Impairment
- ADHD
Cognitive Functions Covered
- Impulsivity
- Decision making
Typical Training Times (depends on strain and age)
- 1-2 weeks to train to touch the screen and initiate the task
- ~13 sessions training to the task
