For the updated test, kids got to choose their preferred treat: M&Ms, marshmallows, or animal crackers. Some scholars and journalists have gone so far as to suggest that psychology is in the midst of a replication crisis. In the case of this new study, specifically, the failure to confirm old assumptions pointed to an important truth: that circumstances matter more in shaping childrens lives than Mischel and his colleagues seemed to appreciate.

Mischels marshmallow test inspired more-elaborate measures of self-control and deeper theories linking impoverished environments to diminished self-control. The air pockets in a marshmallow make it puffy and the lack of density makes it float. "It occurred to me that the marshmallow task might be correlated with something else that the child already knows - like having a stable environment," one of the researchers behind that study, Celeste Kidd. Ultimately, the new study finds limited support for the idea that being able to delay gratification leads to better outcomes. A group of German researchers compared the marshmallow-saving abilities of German kids to children of Nso farmers in Cameroon in 2017. Mischel still hasn't finished his experiment.

Most surprising, according to Tyler, was that the revisited test failed to replicate the links with behaviour that Mischels work found, meaning that a childs ability to resist a sweet treat aged four or five didnt necessarily lead to a well-adjusted teenager a decade later. The purpose of the study was to understand when the control of delayed gratification, the ability to wait to obtain something that one wants, develops in children.

They described the results in a 1990 study, which suggested that delayed gratification had huge benefits, including on such measures as standardized-test scores. Similarly, in my own research with Brea Perry, a sociologist (and colleague of mine) at Indiana University, we found that low-income parents are more likely than more-affluent parents to give in to their kids requests for sweet treats.
