Michel and his team then went behind the one-way glass and filmed for 15 minutes.
Footage of these experiments, which were conducted over several years, is poignant, as the kids struggle to delay gratification for just a little bit longer. Some cover their eyes with their hands or turn around so that they can’t see the tray. Others start kicking the desk, or tug on their pigtails, or stroke the marshmallow as if it were a tiny stuffed animal. One child, a boy with neatly parted hair, looks carefully around the room to make sure that nobody can see him. Then he picks up an Oreo, delicately twists it apart, and licks off the white cream filling before returning the cookie to the tray, a satisfied look on his face.
The genius of the experiment was not in discovering what percentage of children delayed gratification and how that might correlate to sex, age, race, ethnicity or income, but in following the children with a longitudinal study for the rest of their lives.
As they matured and became adults, the kids who had shown the ability to wait got better grades, were healthier, enjoyed greater professional success, and proved better at staying in relationships—even decades after they took the test. They were, in short, better at life.
The results of our study indicate that young children’s performance on sustained delay-of-gratification tasks can be strongly influenced by rational decision-making processes. If self-control capacity differences were the primary causal mechanism implicated in children’s wait-times, then information about the reliability of the environment should not have affected them. If deficiencies in self-control caused children to eat treats early, then one would expect such deficiencies to be present in the reliable condition as well as in the unreliable condition. The effect we observed is consistent with converging evidence that young children are sensitive to uncertainty about future rewards.***To be clear, our data do not demonstrate that self-control is irrelevant in explaining the variance in children’s wait-times on the original marshmallow task studies. They do, however, strongly indicate that it is premature to conclude that most of the observed variance—and the longitudinal correlation between wait-times and later life outcomes—is due to differences in individuals’ self-control capacities. Rather, an unreliable worldview, in addition to self-control, may be causally related to later life outcomes, as already suggested by an existing body of evidence.
Attention control strategies and cognitive transformations/reappraisals can 'cool' the immediate temptations and 'heat' the delayed consequences is what's important.***The point I am trying to make is that if we are going to talk seriously about taking long term consequences like climate change into account, we've got to make the consequences hot. We have to really make them hot. And that's not easy to do.One of the reasons that it is not easy to do is because that limbic system, that hot system that activates automatically when you have high stress, is there for good reason.
Mischel’s main worry is that, even if his lesson plan proves to be effective, it might still be overwhelmed by variables the scientists can’t control, such as the home environment. He knows that it’s not enough just to teach kids mental tricks—the real challenge is turning those tricks into habits, and that requires years of diligent practice. “This is where your parents are important,” Mischel says. “Have they established rituals that force you to delay on a daily basis? Do they encourage you to wait? And do they make waiting worthwhile?” According to Mischel, even the most mundane routines of childhood—such as not snacking before dinner, or saving up your allowance, or holding out until Christmas morning—are really sly exercises in cognitive training: we’re teaching ourselves how to think so that we can outsmart our desires. But Mischel isn’t satisfied with such an informal approach. “We should give marshmallows to every kindergartner,” he says. “We should say, ‘You see this marshmallow? You don’t have to eat it. You can wait. Here’s how.’ “
