We’re very familiar with the marshmallow test and my son is extremely proud that my 4 year old grandson passes with flying colors…
but I think there is a very serious correlation vs. causation issue with this research.
Kids who grow up in stable, predictable environments also learn, early on, that deferred gratification is a safe and useful strategy. If you grow up in a world where there are plenty of marshmallows, and the adults consistently do what they say they are going to do … then putting aide a marshmallow in the hopes of getting a 2nd one is an easy choice to make.
My kids always used to hoard their halloween candy for months – they would come home, sort through and throw away or trade with each all the candies they didn’t like, and stash their favorites in a bedroom drawer for future use. Why? I never suggested that they do that, but they knew that they would always have pocket money for candy whenever they wanted, and that I wouldn’t take away or even touch their stash. (OK, I admit it, I used to steal my daughter’s smartie’s - I love those things - but at least most of her stash was preserved).
But what if a kid grows up in an environment where resources are short? Where sometimes there is nothing at all to eat at home? Where they can’t simply ask their mom to buy a bag of marshmallows at the grocery store whenever they want?
Not only do those kids not learn to defer gratification-- but for them, that’s a stupid choice. They have grown up in a world where if they don’t grab the marshmallow, someone else will take it an eat it, sooner rather than later. And a grownup’s promise of a 2nd marshmallow when the grownup returns could very well be a ruse— heck, even the claim that the grownup will be back at all is not going to be trusted by a kid who can’t even count on parents showing up at predictable times.
So rather than looking at how the kid performs on the test – I think you have to look at the overall environment that kid is growing up in, and the larger impact that will have on all choices and options available throughout life. Basically the marshmallow test is a culturally biased, rich kid’s test. “Rich” in relative terms – my grandson has been brought up on “starving student” economics, but it’s a stable environment. So yeah, grandson passes the test --he does even better, because he learned pretty early that not only was food plentiful in his would, but adults could be easily manipulated into giving him all sorts of sweets, simply by virtue of his cuteness.
I think you can teach the marshmallow skills, but that isn’t going to solve the problems faced by kids who grow up in poverty, instability, or who experience neglect or abuse from adults around them.
