Amount and time exert independent influences on intertemporal choice.

ABSTRACT: Intertemporal choices involve trade-offs between the value of rewards and the delay before those rewards are experienced. Canonical intertemporal choice models such as hyperbolic discounting assume that reward amount and time until delivery are integrated within each option prior to comparison^1,2. An alternative view posits that intertemporal choice reflects attribute-wise processes in which amount and time attributes are compared separately^3-6. Here, we use multi-attribute drift diffusion modelling (DDM) to show that attribute-wise comparison represents the choice process better than option-wise comparison for intertemporal choice in a young adult population. We find that, while accumulation rates for amount and time information are uncorrelated, the difference betwe
