To test the theory of a person’s ability to delay gratification, the Stanford Marshmallow Experiment (1972), conducted by Prof. Walter Mischel, at Stanford University, California, studied a group of four-year-old children, each of whom was given one marshmallow, but promised two on condition that he or she wait twenty minutes, before eating the first marshmallow. Some children were able to wait the twenty minutes, and some were unable to wait. The Stanford Marshmallow Experiment indicates that good impulse control might be psychologically important for academic achievement and for success in adult life.
