Find out how parents, teachers, and individuals can dramatically improve their self-control skills with effective techniques and strategies. Prepare to be enlightened on the power of self-control and its correlations to success, relationships, and personal development.

The Marshmallow Test

In a clinical test called the Marshmallow Test, children were given the choice between eating a treat now or waiting to receive two treats later. The test provided insights into human behavior as some children ate the treat right away, while others managed to resist by distracting themselves from it. Researchers taught the children distraction techniques beforehand, such as if-then plans, which significantly helped them resist the treat. The Marshmallow Test has profound implications that will be explored further in the subsequent parts of the book.

The Battle of Two Systems

Our ability to resist temptation is a never-ending tug between the hot and cool systems within our body. The hot system reacts instantly to our emotions and basic needs, making it difficult to resist immediate gratification. On the other hand, the cool system, located in our prefrontal cortex, is responsible for self-control and planning. While the cool system develops over the course of childhood, our hot system is functional from birth, which explains why it’s harder for children under four to resist temptation. As we grow older, our cool system improves, but it’s still developing through adolescence. Most adults have a fully functional cool system, which is why they can resist long-term rewards. The two systems tend to work together, so that when one is active, the other becomes less active. Teens find it challenging to resist the temptation of drugs or alcohol due to their still-developing cool system. Therefore, learning to control these two systems and attain self-discipline is a crucial skill that one should keep honing over time.

Improving Self-Control

Self-control is a skill that can change depending on our environment and experiences. While partly genetic, self-control is mostly shaped by our upbringing. Parents have an incredibly formative role in shaping the prefrontal cortex of children. Teaching distraction techniques can cultivate self-control in children, while not doing so can cause long term issues. Even those with innate abilities to self-control can improve on this skill given the right environment and experiences.

Self-Control Is Context-dependent

Self-control is not a fixed trait and is context-dependent. The book explains that someone who can’t control themselves sexually might be able to control themselves at work, and we choose the situations in which we exercise our self-control. We decide whether to give into temptation by considering the consequences, our goals, and the strength of the temptation itself. Self-control is limitless, and viewing it as positive can increase productivity. An experiment conducted by researchers showed that those who viewed self-control as energizing were able to perform better on a handgrip task. Thus, if you think of self-control as limitless, you can increase your productivity and avoid getting exhausted quickly.

The Marshmallow Test and Success

The Marshmallow Test conducted on young children showed that their ability to delay gratification correlated with their success as adults. Researchers found that those who waited longer for their rewards were better at concentrating, planning ahead, scored higher on SATs, were better at maintaining personal relationships, and had more activation in their prefrontal cortex. On the other hand, those who had less self-control had more activation in their ventral striatum and were more susceptible to addictive substances. Even though the children were very young when they participated in the test, they already had formed self-control habits that stayed with them as they grew older. Therefore, the Marshmallow Test is a useful indicator of a child’s future development and behavior.
