[PAR] [TLE] Stanford marshmallow experiment [SEP] The Stanford marshmallow experiment was a series of studies on delayed gratification in the late 1960s and early 1970s led by psychologist Walter Mischel, then a professor at Stanford University.  In these studies, a child was offered a choice between one small reward provided immediately or two small rewards (i.e., a larger later reward) if they waited for a short period, approximately 15 minutes, during which the tester left the room and then returned.  (The reward was sometimes a marshmallow, but often a cookie or a pretzel.)  In follow-up studies, the researchers found that children who were able to wait longer for the preferred rewards tended to have better life outcomes, as measured by SAT scores, educational attainment, body mass index (BMI), and other life measures.

He is the Robert Johnston Niven Professor of Humane Letters in the Department of Psychology at Columbia University.  A "Review of General Psychology" survey, published in 2002, ranked Mischel as the 25th most cited psychologist of the 20th century.
