Joachim de Posada says, Don't eat the marshmallow yet Video on TED.com

Here is an engrossing experiment about the relation between delaying gratification and its impact on success.Joachim de Posada states that if our ability of delaying gratification is good we are more likely to be successful in our lives.Basically kids aged 4-6 years old are left in a room by themselves while being given a marshmallow and they are told to not eat the marshmallow for 50 minutes in order to get another one.According to Joachim de Posada the kids who didnt eat the marshmallow are more likely to be successful later on in their lives.I do value delayed gratification and endurance,however this speech left me with some questions in my mind.Would the childeren act the same way if they werent told how long they had to wait? and does telling them to not eat the marshmallow accually cause an opposite reaction in their minds?
The kids are totally adorable by the way :)
