Delay discounting is a form of impulsive choice in which the perceived value of a reward decreases as delay to reward increases. Increased rates of delay discounting have been associated with a multitude of psychopathologies, including substance use disorders. Translational studies using rodent models have broadened our understanding of this behavior and been used identify potential therapeutic interventions. It is common practice to restrict weight when using animal models to increase both motivation and engagement with the discounting task. Results from this study emphasize the importance of developing a more standardized weight restriction procedure in studies using food restriction as a way to increase animal motivation in discounting tasks. Future research may look to determine the role of feeding times and metabolism on delay discounting rates.
