Tamarin Monkey Repeated-Game Experiments:
Quicktime Movie Clip: Click here or on the photo below.
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.
