Mental Math and the Fine-Tuning of Emotions (The Dana Foundation)
“You often hear the word “calculating” used to describe someone who always seems to act deliberately, guided by reason rather than emotion. The idea behind this characterization is that human nature straddles a deep divide between thinking and feeling, but current research suggests otherwise. Brain-imaging studies, in particular, reveal an overlap between the sites in the brain that make it possible for us to perform mental arithmetic and those that enable us to regulate our emotions. In fact, these two dissimilar-seeming functions are housed in the same neighborhood of the cerebral cortex. But they don’t just reside near each other—they actually work together. “It’s possible that training the brain with mental math strengthens the capacity for emotional reappraisal, or perhaps continually running the process of emotional reappraisal increases the ability for mental calculations of other kinds like mental arithmetic.”

Here is a fun brain teaser from puzzle master Wes Carroll.
Tipping the Scales
The top two scales in the image at the right are in perfect balance. How many diamonds will be needed to balance the bottom set?
This puzzle helps you work out your executive functions –supported in the frontal lobes— by using your pattern recognition, hypothesis testing, and logic.
First add up the number of clubs in the first two scales (5). Then count how many clubs are in the bottom scale (5). The do the same with the spades, which gets you 5 and 5. There are 4 diamonds in the top two balanced scales. Therefore, it must take 4 diamonds to balance the third scale since all the other measurements are the same.
