Doebel and Munakata (2018) discovered that delay ofgratification by children is influenced by social context. All children weretold that they were in the “green group” and were placed in a room with asingle marshmallow. Participants were told that they could either eat thesingle marshmallow now or wait for the experimenter to return with twomarshmallows. Before choosing between one marshmallow now or two later,children were randomly assigned to one of two conditions. They were told thateither (1) other children in the green group waited and kids in the orangegroup didn’t wait or (2) other children in the green group didn’t wait and kidsin the orange group waited. Children were more likely to choose to wait afterbeing told that other members of their group waited.
