The Stanford Marshmallow Test is one of psychology's most famous studies. For those who are unfamiliar, the study was invented by Walter Mischel, and involved testing the willpower of children to delay gratification, with marshmallows. Here is a quick description, via the New Yorker:
In the original test, which was administered at the Bing Nursery School, at Stanford, in the nineteen-sixties, Mischel's team would present a child with a treat (marshmallows were just one option) and tell her that she could either eat the one treat immediately or wait alone in the room for several minutes until the researcher returned, at which point she could have two treats.
