Final answer:
The marshmallow challenge helps people identify their level of self-control and its impact on future success.
Step-by-step explanation:
The marshmallow challenge helps people to identify their degree of self-control and its impact on their future success. In the original study by Mischel and his colleagues, preschool children were given the choice to eat one marshmallow immediately or wait for the researcher to return and receive two marshmallows. The children who displayed more self-control and were able to delay gratification were found to have higher SAT scores, better peer relationships, and less likelihood of substance abuse issues in high school and adulthood. On the other hand, those with poor self-control in the marshmallow test faced academic and behavioral challenges later in life.
