Long-term studies based on the Marshmallow Test have shown that the children who waited longer for the second marshmallow tended to be more successful later in life.

While the researcher is out of the room, a timer is usually running to determine how long the child waits for the second marshmallow. Others consider the benefits of waiting and don't eat the first marshmallow while the researcher is away. Some children behave impulsively and eat the first marshmallow as soon as the researcher is out of sight. They usually explain that if the marshmallow is still there when they come back, they will give the child a second marshmallow, and then the child can eat both marshmallows. It generally begins with a researcher giving a child one marshmallow and telling the child that they (the researcher) will leave the room. The Marshmallow Test has been used extensively to study impulsive behavior in children. Some tests of impulsivity have been used for years because they seem to show the differences between impulsive and non-impulsive behavior very well.

Several studies have been done to find out more about impulsive behavior. Rather than thinking through your options, impulsive behavior typically involves acting on a whim without considering the consequences or long-term repercussions of your decision. Impulsive behavior can be challenging to define, but in general, it is thought of as unplanned behavior.
