Low-serotonin levels increase delayed reward discounting in humans.
Previous animal experiments have shown that serotonin is involved in the control of impulsive choice, as characterized by high preference for small immediate rewards over larger delayed rewards. Previous human studies under serotonin manipulation, however, have been either inconclusive on the effect on impulsivity or have shown an effect in the speed of action-reward learning or the optimality ...
متن کاملRole of serotonin in delayed reward choice in humans
Although deregulation of the neuromodulator serotonin has long been implicated in disorders such as depression and impulsivity, its normal function in the human brain has remained enigmatic. In animals, decreased serotonin levels increase impulsive choice[1,2], presumably via an increase in the rate of discounting[2], which renders large delayed rewards less valuable than small immediate reward...

متن کاملLethal forethought: delayed reward discounting differentiates high- and low-lethality suicide attempts in old age.
BACKGROUND The decision to commit suicide may be impulsive, but lethal suicidal acts often involve planning and forethought. People who attempt suicide make disadvantageous decisions in other contexts, but nothing is known about the way they decide about the future. Can the willingness to postpone future gratification differentiate between individuals prone to serious, premeditated and less ser...
متن کاملDelayed Reward Discounting and Alcohol Misuse: The Roles of Response Consistency and Reward Magnitude.
Delayed reward discounting (DRD) is a common index of impulsivity that refers to an individual's devaluation of rewards based on delay of receipt and has been linked to alcohol misuse and other maladaptive behaviors. The current study investigated response consistency and reward magnitude effects in two measures of DRD in a sample of 111 undergraduates who consumed an average of 10.7 drinks/wee...
