Brain exercise: Frontal and Parietal Lobes

Let’s now exercise our Frontal Lobes (that deal with working attention, among other things), and Parietal Lobes (visual interpretation). (Basic brain anatomy here)

Quick!, count the number of times the number “7” appears below. Then, count the total of both “1”s and “2”s, trying to add the total number of both as you see either (this is, don’t just count all the “1”s, and then the “2”s)

    Well, first, congratulations to everyone who has tried, since this type of exercise has been used by the military to improve attention.

    There are
    – 36 7s
    – 23 1s and 2s combined (4 1s, 19 2s)

    If you want more practice, there are a few other digits out there 🙂
