Self Control - The Mischel Paradigm

The Mischel Paradigm

In the 1960s, Walter Mischel tested four-year-old children for self-control in "The Marshmallow Test": the children were each given a marshmallow and told that they can eat it anytime they want, but if they waited 15 minutes, they would receive another marshmallow. Follow up studies showed that the results correlated well with these children's success levels in later life.

A strategy used in the marshmallow test was the focus on "hot" and "cool" features of an object. The children were encouraged to think about the marshmallow's "cool features" such as its shape and texture, possibly comparing it to a cotton ball or a cloud. The "hot features" of the marshmallow would be its sweet, sticky tastiness. These hot features make it more difficult to delay gratification. By focusing on the cool features, the mind is adverted from the appealing aspects of the marshmallow, and self-control is more plausible.

Years later Dr. Mischel reached out to the participants of his study who were then in their 40's. He found that those who showed less self-control by taking the single marshmallow in the initial study were more likely to develop problems with relationships, stress, and drug abuse later in life. Dr. Mischel carried out the experiment again with the same participants in order to see which parts of the brain were active during the process of self-control. The participants received scans through M.R.I to show brain activity. The results showed that those who exhibited lower levels of self-control had higher brain activity in the ventral striatum, the area that deals with positive rewards.

Reviews concluded that self-control is correlated with various positive life outcomes, such as happiness, adjustment and various positive psychological factors. Self-control was also negatively correlated with sociotropy which in turn is correlated with depression.
