Summary: The discounted value of large reward option may not be the main contributor to variability in animals' choices. Exploratory decision making rather than changes in reward valuation may lead to persistent anchoring effects in probability discounting. Choice response times reflect the degree of conflict caused by uncertainty and temporal cost, but were not linked with differences in locomotor activity reflecting chamber exploration.

Summary: The study found that the magnitude effect is present for monetary gains but not for monetary losses in delay discounting and probability discounting. The subjective probability of receiving future outcomes is amount-dependent for gains but not for losses. The risk associated with future payoffs of different magnitudes may explain the magnitude effect.

Summary: This study reveals differences in behavioral tasks (lower discounting rates) but not in patterns of neural activation between gamblers and non-gamblers.

Summary: This study investigated the impact of mask wearing on the effect of proposer's facial trustworthiness on discounting behavior. The results indicated that a masked untrustworthy proposer increased both delay and probability discounting parameters, although the effect was not as significant as that of an untrustworthy proposer without a mask.

Summary: The study found that food insecurity is associated with more impulsive food choice, but its relation with other monetary discounting and probability discounting is contingent upon other demographic factors.

Summary: Impulsive behavior was measured through a delay-discounting task, and it was found that the presence of a concurrent distractor stimulus increased LL reinforcers. The experiments tested the hypothesis that the concurrent stimulus could become a Pavlovian conditioned stimulus. Results showed that the concurrent stimulus was less effective in the Red-Green group compared to the Red-Only group. Both the yellow key-light and the houselight as concurrent stimuli were effective in increasing LL reinforcers.

Summary: The study found that in humans consuming delayed real liquid rewards in intertemporal choice, the activity in different regions of the ventral striatum is related to behavioral impulsivity, impulsive individuals show activity in the anterior prefrontal cortex, and there are differences in neural mechanisms.

Summary: Theoretical accounts on dopamine's role in intertemporal choice have conflicting opinions, with some saying dopamine promotes delay of gratification and others saying it reduces patience. This study provides empirical support for a novel process model that reconciles these conflicting accounts. The findings suggest that dopamine contributes to evidence accumulation and starting bias in the decision-making process.

Summary: The study shows that public sector employees tend to overestimate risks, tolerate delay, and exhibit biases towards the public sector. However, decision makers do not automatically change their economic discounting behavior when transitioning from a public to a private sector environment.

Summary: Temporal reward discounting refers to the decrease in the value of a reward as the delay increases. This study investigated the decision-making patterns of rats when choosing between differently timed electric shocks and rewards. The results suggest that the proximity of a shock to a subsequent reward influences the devaluation of the reward. Depending on the timing of the shock-reward contiguity, rats may prefer later rewards of equal magnitudes.

Summary: This study developed a cortical assay of impulsive choice for immediate rewards and found consistent associations with drug use and delay discounting task performance. The assay was also uniquely associated with psychiatric disorders that share impulsivity as a core feature.

Summary: The study found that the hyperactivity-impulsivity domain of ADHD symptoms was specifically associated with a preference for small immediate rewards, which in turn was related to executive function problems and weak learning strategies in daily life.

Summary: This study found that Reward Positivity (RewP) can reflect the integrated sum of instantaneous and delayed consequences of a singular outcome in a stable manner. It also indicated that the medial frontal cortex receives fine graded information about complex action outcomes. Moreover, the sensitivity of RewP to the three outcome dimensions reflects stable trait-like individual differences in reward processing.

Summary: Scarcity goods are generally perceived as high value in real-world and empirical studies. The objective of this study was to determine how scarcity evaluation changes over time. The results show that ordinary goods have a more negative amplitude compared to scarcity goods. The effect is primarily derived from ordinary trials rather than scarcity trials.

Summary: This study used resting-state functional magnetic resonance imaging (RS-fMRI) to measure spontaneous neural activity in healthy young adults and used the Monetary Choice Questionnaire to measure levels of delay discounting. The study found that the fractional amplitude of low-frequency fluctuations (fALFF) of the left insula was positively correlated to delay discounting, and its connectivity to the anterior cingulate cortex was related to participants' behavioral performance.
