A group of researchers are interested in the development of delay strategies. A group of 3, 5, and 7-year-old children are individually taken to a research room. On the table is a plate of marshmallows. Children are told they can play with the toys, but should not eat the marshmallow. Children are observed through a one-way mirror to see if they looked at, touched, licked, or ate the marshmallows. Children are given a score for delay of gratification.
