Daniel Goleman: Yes, You Can Build Willpower (meditate on neuroplasticity!)

(Editor’s note: Daniel Goleman is now conducting a series of audio interviews including a great one with Richard Davidson on Training the Brain. We are honored to bring you this guest post by Daniel Goleman, thanks to our collaboration with Greater Good Magazine.) 

Yes, You Can:

New research suggests we can build our willpower

– By Daniel Goleman

Those of us who struggle to resist junk foods or otherwise suffer a lack of willpower will be heartened by some good news from neuroscience. But there’s some bad news, too.

First, the bad news. A slew of studies suggest that we each have a fixed neural reservoir of willpower, and that if we use it on one thing, we have less for others. Tasks that demand some self-control make it harder for us to do the next thing that takes willpower.

In a typical experiment on this effect, one group of people was made to watch a video of a boring scene; another was not. Then both groups had to circle every “e” in a long passage of writing. The result? The people who had to first sit through the boring video gave up faster. The same loss of persistence has been found when people try to resist tempting foods, suppress emotional reactions, or even make the effort to try to impress someone.

This all suggests we have a fixed willpower budget, one we should be careful in spending. Some neuroscientists suspect that self-control consumes blood sugar, which takes a while to build up again; thus, the depletion effect.

But the good news is that we can grow our willpower; like a muscle, the more we use it, the more it gradually increases over time. But doing this takes, of all things, willpower.

As the muscle of will grows, the larger our reservoir of self-discipline becomes. So people who are able to Read the rest of this entry »

Gardening your hippocampus with Physical and Mental Exercise

Physical Fitness Improves Spatial Memory, Increases Size Of Brain Structure (Science Daily)

- “Now researchers have found that elderly adults who are more physically fit tend to have bigger hippocampi and better spatial memory than those who are less fit.”

- “Certain activities are believed to modify hippocampus size in humans. For example, a study of London taxi drivers found that the posterior portion of the hippocampus was larger in experienced taxi drivers than in other subjects. And a study of German medical students found that the same region of the hippocampus increased in size as they studied for their final exams.”

- “Studies also have found that the hippocampus shrinks with age, a process that coincides with small but significant cognitive declines. The rate at which this occurs, however, differs among individuals.”

“Tis better to give than receive”: oxytocin and dopamine

Jeffrey Gonce, a Psychology teacher at Red Land High School (West Shore School District, PA) just asked his students to “complete a project describing a recent brain (or genetic) study that affects behavior.” The students could opt to post their articles online, and Jeffrey was kind enough to send us a link to read the results.

We enjoyed the overall level of the essays (you can read them all here), and truly enjoyed reading a beautiful, well-researched and better written essay by Alexandra M, 15. Which, incidentally, quotes from one of our favourite popular science books on the brain, John Ratey’s A User’s Guide to the Brain.

Enjoy!

It’s Christmas morning, and your brother rushes downstairs to see what “Santa” brought him. The morning goes by in a flurry of colorful wrapping paper and stringy ribbons until all that’s left is a big present in the center of your brother’s lap. The present that “Santa” brought him. As he rips open the paper, “Santa’s” chest swells with pride, he feels good and happy. As the brother runs around screaming about his new remote controlled F-14 Tomcat, “Santa” laughs and cleans up. But why did he feel that way? Read the rest of this entry »
