Probability discounting was investigated in children, young adults and older adults the study was designed to systematically replicate a study by green, fry, and myerson (1994) with children, young adults and older adults that found that children were more impulsive than young adults and older adults on a delay-discounting procedure. The purpose of the present study was to investigate temporal and probabilistic discounting in smoker. This study examined relations between adult smokers and non-smokers and the devaluation of monetary rewards as a function of delay (delay discounting, dd) or probability (probability discounting, pd.

Delay and probability discounting occur when the subjective value of an outcome decreases because it is delayed or uncertain, respectively research using monetary outcomes has shown that both types of discounting are influenced by the magnitude of the outcome, but in the opposite direction.
Discounting tasks were comprised of dichotomous choices between smaller, immediate/guaranteed and larger, and delayed/probabilistic monetary values. Discounting delayed and probabilistic rewards: processes and traits and probability discounting also should show a strong positive correlation if both. Delay and probability discountingdelay discounting is the extent to which an individual “discounts” the value of a reward (eg money, food, weight loss, etc) as a function of having to wait for it.
Delay or probability discounting in a model of impulsive behavior: effect of alcohol. Hyperbolic discounting of delayed and probabilistic outcomes has drawn attention in psychopharmacology and neuroeconomics sozou's evolutionary theory proposed that hyperbolic delay discounting may be totally attributable to aversion to a decrease in subjective probability of obtaining delayed rewards (sp) which follows a hyperbolic.
