"There is a long history of research in psychology suggesting that decision making under many different circumstances reflects the interaction of qualitatively different systems. Some researchers have compared emotional (or affective) processes and deliberative (or analytic) processes, whereas others have contrasted automatic and controlled processes."
-The study below lends neuroscientific support to the use of such dual-process models in accounting for intertemporal choice.
"Consistent with previous findings, limbic activation was greater for choices between an immediate reward and a delayed reward than for choices between two delayed rewards, whereas the lateral prefrontal cortex and posterior parietal cortex responded similarly whether choices were between an immediate and a delayed reward or between two delayed rewards."
