Rural Cameroonian pre-schoolers just aced Mischel’s iconic Marshmallow Test

Christian Jarrett:

Walter Mischel’s Marshmallow Test of self-control is one of psychology’s iconic experimental set-ups. First conducted in the 1960s, Mischel told the kids he tested that if they managed to resist eating the marshmallow in front of them until he returned (usually about 15 minutes later), they would be rewarded with a second marshmallow.

The children varied greatly in their powers of restraint and those who performed better displayed some cute distraction strategies, such as singing to themselves and covering their eyes. Perhaps most important, those kids who performed well at the test tended to do well in later life too, in terms of their health, education and career success. Given the huge impact this research has had, it’s amazing that it’s never been exported to a non-Western setting. Until now.
