Emotion is a powerful driver of behavior, sometimes too powerful. Virtually everyone has had the experience of reacting in the heat of the moment only to later regret his or her words or deed. An almond-shaped structure in the center of the brain called the amygdala is a hub for emotional responses. When it’s in high gear, feelings tend to rule the neural roost, blocking the ability to rationally consider the best course of action. Ideally, we would all pause long enough for rational thought to take over—say, after someone cuts us off on the road or criticizes our efforts at work or at home. Some educators believe that such a skill should be taught to everyone at a very young age.

A curriculum called MindUP conceived by actor Goldie Hawn includes an activity called the amygdala shake-up designed to help children understand the need for this sort of patience. For this activity, a teacher creates a crude model of the amygdala from a soda bottle filled with water, sand and glitter. Then, in front of the class (or a single student), she turns over the bottle and shakes up its contents to show what happens when a person gets stressed or upset. Once the glitter and sand are mixed, she rights the bottle and waits for the sand and glitter to settle, explaining that the wait represents the time it takes the amygdala to calm down enough so that a person can make a good choice.

This simple sketch shows kids why it is usually a good idea to stop and take a breath after an event that makes them mad, sad or annoyed. (The rapid response system is better suited to situations involving real danger in which speed is essential. In modern times, however, fast reactions usually create more problems than they solve.) The amygdala shake-up is a lesson in self-regulation, a skill useful in many facets of life. And the use of brain science as a tool for social and emotional learning is a signature aspect of MindUp.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
