Delay of gratification and delay maintenance by rhesus macaques (Macaca mulatta).

@article{citeulike:2188644, abstract = {The authors tested the self-control of rhesus macaques by assessing if they could refrain from reaching into a food container to maximize the accumulation of sequentially delivered food items (a delay-maintenance task).
