Remember the marshmallow kids? The four-year-olds who were tested for their ability to delay taking a sweet back in the late 1960s are still under the microscope as scientists try to fathom the secrets of self control.
According to The New Yorker, the experiment went like this. Children from the Bing Nursery School at Stanford University were invited into a room where they could be observed and allowed to pick a treat from a tray of marshmallows, cookies and pretzel sticks. They were told they could eat it straight away, or they could wait a few minutes and then have two when the researcher returned.
