Claudio Dinapoli Posted 6 months ago Joachim de Posada: Don't eat the marshmallow! It would be interesting to see how a social environment may effect this experiment. No one lives alone in an empty room, on the opposite we see people, for instance in classrooms kids are associated with other peers. So I would run another experiment with many of those 4-years-old children in the same room trying to resist the temptation of an immediate gratification by setting either individual rewards, another Marshmallow to the one already given, or collective ones, and see how they interact with each other and how each one of them is influenced by the rest. This would be a Marshmallow Test step 2.
