#18. Mind teaser to exercise your frontal and parietal lobes

Let’s now exer­cise our frontal lobes (that deal with work­ing mem­o­ry and atten­tion, among oth­er things) and pari­etal lobes (visu­al inter­pre­ta­tion).

Quick!

1. Count the num­ber of times the num­ber “6” appears below (you may need to scroll down).

2. 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, but both at the same time)

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).

    If you nor­mal­ly read left to right, try count­ing find­ing the num­bers scan­ning right to left… it will increase the accu­ra­cy. And, scan­ning from bot­tom to top (if you nor­mal­ly read top to bot­tom) will help you not skip lines.

    first I got 34 6es then I was count again and I got
    33 of 6es.
    I was got only
    27 of 3s and 7s at the same time.

  4. red says:

    33–6
    59–3&7

  5. Kayla says:

    I got exact­ly 33 and 59 sooo excit­ed woohoo!!

  6. anne says:

    19 & 55

    19 & 55
    2nd try:
    33 & 55

  8. ana says:

    33 6s woo hoo!

    I read the instruc­tions that we had to count the 3s and 7s indi­vid­u­al­ly but at the same time so to keep track I count­ed the 3s using num­bers and the 7s using the alpha­bet… and came out with 23 3s and 36 7s = 59 total I’m shocked !!!

  9. DAVIS says:

    I got 33/ 3s.AND I ADDED AS I WENT THRU THE 3S AND 7S CAME UP W/ 332

  10. Susie says:

    Well, if I had been a sol­dier I would have missed one of the ene­mies named “3” and would have mis­tak­en one of my own peo­ple as a “3” or a “7.” Not good in bat­tle!

    I got 32 6’s. And I got 60 7&3’s. I tried it two dif­fer­ent ways. First I tried visu­al­ly match­ing 7’s and 3’s togeth­er to make 10’s so it would be eas­i­er to add. I found myself mark­ing 7’s with my fin­ger on the screen, though, since they were not even­ly matched. Then I tried a dif­fer­ent strat­e­gy which could tech­ni­cal­ly be cheat­ing, I sup­pose. As I came to a 3, I would name them in order such as 3–1, 3–2, 3–3, while also nam­ing the 7’s aloud as I came to them, 7–1, 7–2, …by the end I was at 3–24 and 7–36. I then men­tal­ly added 24 + 36 = 60.
    So, I did them as I went, but sep­a­rate­ly, as well.

    Nice exer­cise! But I’m a bit puz­zled at some­thing: In the text at the top of this page you say this task exer­cis­es the Frontal and Pari­etal lobe, and that the Pari­etal lobe deals with visu­al inter­pre­ta­tion. I thought the Occip­i­tal lobe was the pri­ma­ry visu­al inter­pre­ta­tion cen­tre, and that the Pari­etal lobe main­ly deals with sen­so­ry infor­ma­tion. How come this isn’t an exer­cise main­ly for the Frontal and the Occip­i­tal lobe?

  12. hides says:

    yeah, 33=6’s and 59=3’s + 7’s

  13. Willow says:

    I have a closed head injury and find the exer­cis­es a bit of a men­tal work­out. Since I found your site I try and do a few exer­cis­es every day.

  14. lizzy says:

    6 = 29
    3 & 7 = 59

  15. Neeti says:

    33 and 59 !

    I got 32 and 58 not bad one way!
