Lower delay discounting (better self-control) is linked to higher intelligence, but the basis of this relation is uncertain. To investigate the potential role of working memory (WM) processes, we assessed delay discounting, intelligence (g), WM (span tasks, 3-back task), and WM-related neural activity (using functional magnetic resonance imaging) in 103 healthy adults. Delay discounting was negatively correlated with g and WM. WM explained no variance in delay discounting beyond that explained…

HighlightsFirst comprehensive review of the systems controlling delay discounting.Discounting appears to be emergent from system interactions.Discounting appears more linked to impulsivity than
Remember the Future II: Meta-analyses and Functional Overlap of Working Memory and Delay Discounting
TLDR
A portion of the left lateral prefrontal cortex is a unique location where delay discounting and working memory processes overlap in the brain and represents a therapeutic target for improving behaviors that rely on the integration of the recent past with the foreseeable future.
The effect of future time perspective on delay discounting is mediated by the gray matter volume of vmPFC
TLDR
The gray matter (GM) cortical volume is quantified using voxel‐based morphometry (VBM) methods to investigate the effect of TP on delay discounting (DD) across two independent samples and provides a new perspective from neural basis for explaining the relation between DD and future TP.
Delay discounting and task performance consistency in patients with schizophrenia
To study impaired goal-oriented behavior in schizophrenia (SZ), we used a delay discounting task, which consists of a series of choices between receiving a small immediate or larger delayed reward.
The neuroanatomical correlates of individual differences in delay discounting: A voxel-based morphometry study
Delay discounting refers to the reduction in the present value of a future reward as the delay to that reward increases, which is related to various problematic behaviors, such as substance abuse. In
Neural and behavioral correlates of episodic memory are associated with temporal discounting in older adults
TLDR
It is found that performance on neuropsychological measures of episodic memory retrieval was associated with temporal discounting, such that people with better memory discounted delayed rewards less, and that a decline in medial temporal lobe structural integrity may impact temporal Discounting.
fMRI reactivity on a delay discounting task predicts weight gain in obese women
TLDR
fMRI of obese women during performance of a delay discounting task found that more difficult compared to easy DD trials resulted in activation in putative executive function areas of the brain, the middle and inferior frontal gyri, and medial prefrontal cortex, and less activation on difficult vs. easyDD trials predicted a greater rate of weight gain.

Common Neural Correlates of Intertemporal Choices and Intelligence in Adolescents
TLDR
Findings provide evidence for common neural correlates of intertemporal choice and intelligence, possibly linked by valuation as well as executive functions.
Factors Affecting Temporal Discounting in Older Adults
People often make decisions involving trade-offs between smaller immediate and larger delayed rewards. In intertemporal choices such as these, individuals tend to discount the value of future

Preference for Immediate over Delayed Rewards Is Associated with Magnitude of Ventral Striatal Activity
Discounting future outcomes as a function of their deferred availability underlies much of human decision making. Discounting, or preference for immediate over delayed rewards of larger value, is
