Delay Discounting Predicts Restraint in a Laboratory Model of Smoking Abstinence Open
Most cigarette smokers say that they want to quit, but few attempts at smoking cessation are successful. To examine factors predicting the ability to quit, researchers have examined various behaviors. Heightened delay discounting, preferen…

Genome‐wide association study of delay discounting in <span>Heterogeneous Stock</span> rats Open
Delay discounting refers to the behavioral tendency to devalue rewards as a function of their delay in receipt. Heightened delay discounting has been associated with substance use disorders and multiple co‐occurring psychopathologies. Huma…

Delay Discounting Measured Using an Adjusting Amount Procedure v1 Open
Delay discounting is the process by which outcomes (rewards or punishment) are devalued as a function of the delay to their occurrence. The adjusting amount procedure enables researchers to measure how much an individual discounts the valu…

Environmental enrichment promotes adaptive responding during tests of behavioral regulation in male heterogeneous stock rats Open
Organisms must regulate their behavior flexibly in the face of environmental challenges. Failure can lead to a host of maladaptive behavioral traits associated with a range of neuropsychiatric disorders, including attention deficit hyperac…

Alcohol‐induced changes in mesostriatal resting‐state functional connectivity are linked to sensation seeking in young adults Open
Background Studies in animals and humans suggest that greater levels of sensation seeking and alcohol use are related to individual differences in drug‐induced dopamine release. However, it remains unclear whether drug‐induced alterations …

Reward Maximization Assessed Using a Sequential Patch Depletion Task in a Large Sample of Heterogeneous Stock Rats Open
Choice behavior requires animals to evaluate both short- and long-term advantages and disadvantages of all potential alternatives. Impulsive choice is traditionally measured in laboratory tasks by utilizing delay discounting (DD), a paradi…

Effort-Related Decision-Making in ADHD Open
ADHD is defined by behavioral symptoms that are not well characterized in relation to ADHD's neurobiological mechanisms. This approach has limited our ability to define ADHD nosology and predict outcomes because it does not systematically …
