We compared temporal and probability discounting of a nonconsumable reward (money) three directly consumable rewards (candy, soda, beer). When were delayed, monetary discounted less steeply than rewards, all which at equivalent rates. probabilistic, however, there was no difference between the rewards. It has been reported that substance abusers discount delayed drug more money, but this may reflect special characteristics drugs or abusers, it general property The present findings suggest abused substances (like beer) share properties other whereas are because they fungible, generalized (conditioned) reinforcers.
