For example, Mischel found that preschoolers who could hold out longer before eating the marshmallow performed better academically, handled frustration better, and managed their stress more effectively as adolescents. A 2018 study on a large, representative sample of preschoolers sought to replicate the statistically significant correlations between early-age delay times and later-age life outcomes, like SAT scores, which had been previously found using data from the original marshmallow test.
