Description:
Two unrelated tamarin monkeys sit adjoining each other. Every
fifteen seconds, a human research assistant brings a tray loaded
with a marshmallow which is just out of reach of one of the monkeys.
The only way that monkey
can eat the treat is if his partner pulls a red handle which
will pull the marshmallow within reach. But pulling the handle
doesn't bring any
reward for the puller: pulling the handle only pays if
the monkey who receives the marshmallow reciprocates by pulling
in the future. Like many human situations, the monkeys must work
together to obtain food and build trust while punishing failures to cooperate.
