Delay discounting has emerged in the scientific literature as a frequent measure of impulsivity across a large number of populations. Because of the high rates of impulsivity in individuals who have sustained a brain injury, measures of discounting that put choices into a temporal context may be particularly valuable in behavioral analyses for this population. However, experimental research with this population is limited. Advantages and challenges for further study in delay discounting with brain injury populations and future directions are discussed.
