A 3-year-old passing the marshmallow test with flying colours will make your day

There’s a psychological test that can be carried out on children, which is supposed to be a predictor of success – providing they pass. We’re not sure we’d pass it ourselves, to be honest, but if anyone would like to send us marshmallows or chocolate, we’ll give it a try.

Richard Mueller, a Professor of Physics, decided to try it on his granddaughter and what happened will warm the cockles of your heart.

Someone on the website Quora asked a question.

Professor Mueller replied with something his little grandchild had said and explained how it had come about.

First, he explained how the test works.

He changed the temptation to suit the child.

It seemed to go well.

However, when she got the chocolate, something even better happened.

What a girl! No wonder her grandfather said this.
