Delay of gratification predicted reports of problematic behavior in a reanalysis of marshmallow test data using theory-driven covariates.

“One of them is named Yuko Munakata and her team. They took the same data set and they reanalyzed it with a different set of assumptions, a lot more conservative. So rather than throwing in 30 coariantss, they put in theorydriven coariantss, ones that made sense from what we know already about research as opposed to like throwing in the kitchen sink. Um, and when they did that, they still found that delay of gratification predicted reports of problematic behavior, which suggests a very clean replication of the original marshmallow test.”
