The neurodevelopment of delay discounting for monetary rewards in pre-adolescent children

Abstract Children are found to exhibit high degrees of delay discounting compared with adults in many delay discounting studies, which might be due to the asynchronous development of “bottom-up” and “top-down” neural systems. However, the temporal dynamics associated with the two systems in the deve...
