Influence of Pramipexole on Probability Discounting and Ventral Pallidal Function: Assessments in Parkinsonian-Like Rats
… we first developed a behavioral paradigm (i.e., probability discounting) to measure risk-taking, one aspect of gambling. Utilizing this paradigm, we determine if risk-taking was altered after acute and/or chronic pramipexole treatment. We incorporated an animal model of PD in this study to …

Delay and probability discounting: a longitudinal study of neural, cognitive, and emotional processes contributing to adolescent development.
… longitudinally over a two-year period. Delay and probability discounting tasks were used to assess decision-making. Change in discounting was examined in relation to baseline intelligence, working memory performance, personality factors, and internalizing and externalizing behaviors. In addition, …

Reciprocal Discounting: Investigating Altruistic Choice and Reciprocation with Others
… changes in some other variable. In the case of probability discounting, value decreases as the probability of receiving the outcome decreases. Whereas with social discounting, value decreases with increases in the social distance of the person receiving that outcome. A weak correlation has been …

Discounting of Hypothetical Monetary Outcomes that are Both Delayed and Probabilistic
… both by the delay until its receipt: delay discounting) and by the likelihood of its receipt: probability discounting). Despite being well described by the same hyperboloid function, delay and probability discounting involve fundamentally different processes, as represented by the opposite …

Discounting of Probabilistic Reinforcers by Pigeons
<p>The phenomenon of probability discounting - the decrease in the subjective value of an outcome as the likelihood of its receipt decreases - has been an increasingly explored area of research with human participants, but has received little attention with nonhuman animals. The few studies that …

Is It Time? Examining the Effects of Episodic Imagining on Reward Discounting
… personal cueing greatly reduces future reward discounting. Despite this robust finding, it is unclear whether this modulatory effect is due to the induction of episodic imagining. If so, the effect should not generalize to forms of discounting that are without a temporal component. To test …

Ruolo dei neurosteroidi nella modulazione dopaminergica
… tested the drug like FIN in a reserpinized rat probability discounting task, a behavioral paradigm aimed at capturing critical behavioral aspect of gambling disorder, namely the preference for large, uncertain rewards, rather than small certain rewards.

Dimension Reduction on Measures of Impulsivity
… Color-Word Interference Test, and the Delay and Probability Discounting Task (DPDT) – all tests performed in a Latin-square determined order by each of 151 students. Findings not only indicate that convergent validity was absent for certain measures of impulsivity, but that with future …

Discounting of Delayed and Probabilistic Rewards by Women with and without Binge Eating Disorder
… needed to refine treatments for both conditions. Discounting, an experimental paradigm that examines changes in the value of delayed or uncertain outcomes, may provide an objective assessment of impulsive behavior. Impulsivity may perpetuate binge eating, but discounting tasks have never been …

The economics of addiction: an experimental investigation
… in the addiction literature; e.g., that the probability discounting and hyperbolic discounting models best characterise choice under risk and over time, respectively. But it also replicates a previous finding; i.e., that smokers tend to discount the future more heavily than non-smokers. It …
