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. 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)

1234467889974674657865876576576 3576573625432657346578436578342 2732188582735827456724687343828 7672878682768723682376783768267 2647648823178346432764876774653 7436574386581483627868653873465 

The Answer will appear as a comment on Friday. 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).

    just so i don't forget - i got 33 and 58!

  2. Alvaroon 13 Oct 2006 at 7:05

    Eleanor, very very close!

    6s: 33
    3s and 7s: 59

  3. Todd Lathamon 25 Oct 2006 at 10:25

    I got the same amount as Eleanor did.

    There are 59 3s and 7s combined. Easy to miss one or two of them. Why don’t you print the exercise, and underline the 3s and 7s. The combined number of 3s and 7s, row per row, is:

    Row 1: 8
    Row 2: 11
    Row 3: 9
    Row 4: 12
    Row 5: 10

    i got it right... i was shocked, though. i kept missing 3's and seeing thme after i moved down to the next line. i was sure that number would be wrong!

  9. Alvaroon 13 Dec 2006 at 9:56

    good work, Amy! those missing 3s will probably appear in your dreams now...

  10. Randyon 15 Dec 2006 at 3:40

    I guess I'm not good at deciphering directions. I counted the 6s, then added up the 3s and 7s. In other words, 3-6-9 and 7-14-21 at the same time. My brain feels confused. Ouch.

  11. Alvaroon 15 Dec 2006 at 3:49

    well, that's another take at this exercise. Not bad, in any case!

  12. Wade Marbachon 03 Jan 2007 at 4:10

    I was just told that I have a cyst in Between the Frontal and Parietal lobes.I have lots of headaches.I took the test and came out with32-6s,57-3&7s.I have an appoi. to see the neuroligist in a week.

  13. Alvaroon 05 Jan 2007 at 8:55

    Wade, your performance was very good!

  14. The Science Punditon 20 Jan 2007 at 3:26

    Funny, I counted all 59 3's and 7's, but I missed one of the 6's: I only counted 32.

  15. Alvaroon 20 Jan 2007 at 6:20

    Hola Javier,

    Yes, sometimes we can get distracted in the "easy" tasks...

    pretty impressive job, in any case.

  16. heatheron 09 Mar 2007 at 12:06

    all together 92!

  17. Marylouon 11 Mar 2007 at 4:36

    I got 31 6s and 57 total of 6s and 7s

  19. [...] Gilbert says the reason that "the human being is the only animal that thinks about the future" is that we have a well-developed frontal lobe. Alvaro and Caroline write wonderful entries about the interesting aspects of the frontal lobe all the time at SharpBrains (see here, here, and here). Gilbert says, "The frontal lobe - the last part of the human brain to evolve, the slowest to mature, and the first to deteriorate in old age - is a time machine that allows each of us to vacate the present and experience the future before it happens."

  20. Fleaon 25 Apr 2007 at 8:48

    I got 33 #6
    I misunderstood the directions on the 3's & 7's. I thought you were to scan through one time and keep two seperate running talleys of the 3's and 7's.
    I got 23 #3 and
    36 #7. Still equalls 59 but I guess I did it the hard way.

  21. Alvaroon 25 Apr 2007 at 4:55

    Hi Flea: the goal here is the exercise part, not just to get to the right answer...so it is great that you did it one way. Try now doing it the other way (with same or other 2 digits)

  22. Myrhon 03 Jun 2007 at 9:04

    Okaaay this is strange. I got 33 (6) and 60 (7/3).
    Fun game, though!

  23. Carolineon 03 Jun 2007 at 10:45

    Glad you enjoyed it Myrh!

  24. Juleson 21 Jul 2007 at 7:50

    I did same as flea but got 32 for 6s, 24 for 3s and 27 for 7's. Great dizzy spell after :)

  25. Alvaroon 21 Jul 2007 at 12:20

    good workout, Jules!

  26. Joeon 14 Aug 2007 at 2:45

    I had a brain injry in 1980 that killed the front temperal lobes and I found 32 for 6s and 32 for the 3s and 7s. I express my intrest in this topic and please contact me if I can be of help in your reaserh and development of this non standardized field.

  27. Alvaroon 15 Aug 2007 at 10:51

    Dear Jules and Joe, happy to see you enjoyed the exercise!

    Joe: thanks for sharing your experience, am glad to see your rehab is going well.

    Regards

  28. C.on 25 Aug 2007 at 9:32

    I must have miss understood too! I counted the 6's (33) and added the 3's and 7's (318). Add me to you're research, accident in 2000, 'sheared' closed head injury.
    Executive functions shot! Thanks for the fun!

  29. Nikhilon 14 Sep 2007 at 8:00

    I got 33 and 59!!
    Nice game,really!

  30. Alvaroon 15 Sep 2007 at 3:57

    Glad you got some good exercise!

  31. nisha loyalkaon 01 Oct 2007 at 6:52

    6's 33.total of 3's and 7 is 59

  32. Alvaroon 01 Oct 2007 at 9:16

    Perfect, Nisha!

  33. Exerciseon 01 Oct 2007 at 9:24

    I got it right i was shocked, though.I kept missing 3's and seeing them after i moved down to the next line. i was sure that number would be wrong!

  35. Jazzon 06 Nov 2007 at 10:12

    i got

    > 58 3's and 7's and
    > 33 6's

  36. Jimon 28 Nov 2007 at 5:36

    Heh, I thought we were supposed count seperately the 3s and 7s... 33 6s, 23 3s and 36 7s

  37. Airoson 29 Nov 2007 at 1:10

    I thught I would count well the number of 6's, and latter I would count less 3's and 7's that are. The result is inverse, I counted 32 6's (-1) and the 59 3's and 7's.

  38. roshanon 01 Dec 2007 at 9:45

    i got 92

  39. Sallyon 18 Dec 2007 at 2:34

    Read the directions! The point of the excersice is to count the 3s & 7s separately, in one scan; not combinatorially.

  40. ETon 01 Jan 2008 at 1:46

    I tried to scan all three numbers separately at the same time at first...going crazy trying to keep each apart!!! Then did it as intructed here and that was easy. Still got 33 6's, and 58 3' and 7's.

  41. Mitchon 04 Jan 2008 at 4:30

    O. I got 33 x 6
    But i thought you were supposed to count the 3's and 7's together but keep them seperate :P ugh what a workout, especially seeing as i had to talk to my boss for a minute half way through. 23 x 3's, 35 x 7's.

  42. Markon 06 Jan 2008 at 8:10

    33 and 59

  43. misson 11 Jan 2008 at 11:33

    33 - 6
    59 - 3 & 7

  45. karpagamon 01 Feb 2008 at 11:13

    i got
    6-33 times
    3 & 7's -57

    guess they r close!

  46. Kathyon 04 Feb 2008 at 9:21

    I counted 32 6's and 54 3's and 7's. Think I will open this page on a regular basis as I will be 73 next week and don't want to lose my ability to think.

  47. Alvaroon 04 Feb 2008 at 7:28

    Hello Kathy! thanks for stopping by. If you are going to do this oftent, you can also change the digits you are counting, so the exercise always offer novelty. See you soon

  48. Lauraon 11 Feb 2008 at 3:53

    I got 33 6s, 23 3s and 36 7s, for a total of 59 on the 3s and 7s. I couldn't believe I got it right!

  49. lee martinon 13 Feb 2008 at 4:30

    how can a man work on his brain that increases intiative and increase self regulatory behaviors

  50. Alvaroon 13 Feb 2008 at 8:33

    hello Lee,

    quick general suggestions:

    1) initiative: with practice, starting small, developing confidence, and expanding scope.

    2) self-regulation: practices like breathing and visualization, perhaps complemented with tools for better planning and reflection (diary, To Do lists), or biofeedback. See these articles

  51. Billon 08 Mar 2008 at 2:41

    I got the correct answers on my 2nd try.

    But I did it by counting down each column, instead of across rows.

  52. radhikaon 11 Mar 2008 at 12:14

    33 and 59....
    it was great.

  53. Desire'eon 15 Mar 2008 at 1:44

    Wow, I was shocked to scroll down and see that I got it right, 33 and 59. Cool.

  54. MCameronMon 04 Apr 2008 at 4:55

    59-3 & 7 32 6's now I got to go back and count the 6's again

  55. Lmnopon 18 Jun 2008 at 5:52

    I thought we were supposed to add all 3--I got 92.
