Patience
What is patience? Humans and other animals often make decisions that trade off present and future benefits. Should a monkey eat an unripe fruit or wait for it to ripen? Should I purchase the iPhone at its debut or wait for the price to drop in a few months? In these dilemmas, large gains often require long waits, so decision makers must choose between a smaller, sooner reward and a larger, late...
متن کاملModelling the Effect of Dorsal Raphe Serotonin Neurons on Patience for Future Rewards
Serotonin is a neurotransmitter that is implicated in many basic human functions and behaviours and is closely associated with happiness, depression and reward processing. In particular it appears to be involved in suppressing responses to distracting stimuli while waiting for a delayed reward. Here we present a system level model of the limbic system which is able to generate a serotonin (5-hy...
متن کاملOptogenetic Activation of Dorsal Raphe Serotonin Neurons Enhances Patience for Future Rewards
Serotonin is a neuromodulator that is involved extensively in behavioral, affective, and cognitive functions in the brain. Previous recording studies of the midbrain dorsal raphe nucleus (DRN) revealed that the activation of putative serotonin neurons correlates with the levels of behavioral arousal [1], rhythmic motor outputs [2], salient sensory stimuli [3-6], reward, and conditioned cues [5-...
متن کاملPatience and prosperity
This paper introduces wealth-dependent time preference into a simple model of endogenous growth. The model generates adjustment dynamics in line with the historical facts on savings and economic growth in Europe from the High Middle Ages to today. Along a virtuous cycle of development more wealth leads to more patience, which leads to more savings and even higher wealth. Savings rates and incom...
متن کاملPatience among children
Recent policy initiatives offer cash payments to children (and often their families) to induce better health and educational choices. These policies implicitly assume that children are especially impatient (i.e., have high discount rates); however, little is known about the nature of children's patience, how it varies across children, and whether children can even make rational intertemporal ch...
