Heroin addicts have higher discount rates for delayed rewards than non-drug-using controls.
Fifty-six heroin addicts and 60 age-matched controls were offered choices between monetary rewards ($11-$80) available immediately and larger rewards ($25-$85) available after delays ranging from 1Expand

Impulsivity and cigarette smoking: delay discounting in current, never, and ex-smokers
Abstract Rationale: Impulsivity is implicated in drug dependence. Recent studies show problems with alcohol and opioid dependence are associated with rapid discounting of the value of delayedExpand

Impulsive and self-control choices in opioid-dependent patients and non-drug-using control participants: drug and monetary rewards.
Delay discounting was investigated in opioid-dependent and non-drug-using control participants. The latter participants were matched to the former on age, gender, education, and IQ. Participants inExpand

Toward a behavioral economic understanding of drug dependence: delay discounting processes.
Behavioral economics examines conditions that influence the consumption of commodities and provides several concepts that may be instrumental in understanding drug dependence. One such concept ofExpand

Within-subject comparison of real and hypothetical money rewards in delay discounting.
A within-subject design, using human participants, compared delay discounting functions for real and hypothetical money rewards. Both real and hypothetical rewards were studied across a range thatExpand

Remember the Future: Working Memory Training Decreases Delay Discounting Among Stimulant Addicts
BACKGROUND Excessive discounting of future rewards has been observed in a variety of disorders and has been linked both to valuation of the past and to memory of past events. METHODS To explore theExpand

Delay discounting in current and never-before cigarette smokers: similarities and differences across commodity, sign, and magnitude.
Research has found that nicotine-dependent individuals delay discount monetary gains at a higher rate than matched controls. Delay discount rates, however, have also been found to vary acrossExpand

Behavioral and neuroeconomics of drug addiction: competing neural systems and temporal discounting processes.
We review behavioral- and neuroeconomic research that identifies temporal discounting as an important component in the development and maintenance of drug addiction. First, we review behavioralExpand

Mild opioid deprivation increases the degree that opioid-dependent outpatients discount delayed heroin and money
HeadingAbstractRationale. A growing literature suggests that excessive temporal discounting of delayed rewards may be a contributing factor in the etiology of substance abuse problems. Little isExpand
