Exercise Brain: Frontal and Parietal lobes
By: Alvaro Fernandez
Let’s now exercise our Frontal Lobes (that deal with working memory and attention, among other things) and Parietal Lobes (visual interpretation). (Basic brain anatomy here)
Quick! Count the number of times the number “6” appears below (you may need to scroll down).
Then, count the total of both “3“s and “7“s, trying to add the total number of both as you see either (this is, don’t just count all the “3“s, and then the “7“s)

The Answer appears as a comment below. The most important thing here is not to get the right answer, but to try. This type of exercise has been used by the military to improve attention for decades (now there are more advanced, computer-based, tools, but this keeps being fun).
