#1. The Stroop Test: Great brain teaser to challenge your mental vitality and flexibility

stroop-testReady to test your men­tal vital­i­ty and flex­i­bil­i­ty?

Quick — say aloud what col­or you see in every word, NOT the word you read.

Go from left to right, from top to down. Ready. Set. Go!


Not easy, right? This task is called the Stroop Test, and is used in neu­ropsy­cho­log­i­cal eval­u­a­tions to mea­sure men­tal vital­i­ty and flex­i­bil­i­ty, since per­form­ing well requires strong atten­tion, inhi­bi­tion and self-reg­u­la­tion capa­bil­i­ty (also called exec­u­tive func­tions).

    try focus­ing on the last let­ter of each word to see only the actu­al col­or

  2. Kyriakos says:

    I just made my vision blur­ry so I can­not read just see the col­ors:)

  3. maya says:

    woah that was kin­da realy hard. like at first it was eaasy but then i saw how it changed and it was hard for my brain to try and say the right col­or! it was fun though:]

  4. Raghu says:

    I was able to cor­rect­ly iden­ti­fy the col­or when start­ed from bot­tom.

  5. pavan says:

    hey anoth­er way of going through eas­i­ly is just look at the col­or, and dont let your brain read the spelling at start. Then you can eas­i­ly go through this. It worked for me!!

  6. Bernie says:

    Pos­es no prob­lem
    for those who are

  7. Bernie says:

    The rest of you are

    last word does­n’t
    pass the spellcheck­er,
    but check:

  8. Anoop Jayaram says:

    Nice & Sim­ple One! enjoyed it.

    it chal­lenges our brain’s ten­den­cy to scan through words.

  9. ardit says:

    it was very easy for me.
    maybe because i was tired and my brain for­got to focus on the mean­ing of the words…
    fun­ny.. the best way is not to try hard

  10. Tammy says:

    if you blur your vision its real­ly easy because you cant c the words!

  11. Constantina says:

    I pro­gressed through the first two lines and then got mixed up as i went through the oth­er lines. I have to observe the instruc­tions prop­er­ly.

  12. Florence says:

    Read from the bot­tom and it was faster. Con­cen­tra­tion slows down when read from top to bot­tom. Great exer­cise !!! Thanks.

  13. Brenda Kane says:

    I cheat­ed and took my glass off! Worked fine and fast.
    I put them back on and it was much more dif­fi­cult.
    Hope I’m not one that looks but does­n’t see.
    Thanks, fun.

  14. Tom says:

    If you need­ed to be lit­er­ate you prob­a­bly did­n’t under­stand the exer­cise. bet you got most of them wrong.

  15. I have always had my own trick when doing things like this. I just make my sight blur­ry, so all I can see is the col­or shown and not be able to read the word. [:

  16. tuaua says:

    I recent­ly done the test in my neu­ropsy­cho­log­i­cal assessment.I had a stroke 2yrs ago. I moved thru test slow­ly, found it hard to focus & con­cen­trate but after I gave it a few go’s I got the hang of it .It’s ide­al for brain train­ing & stim­u­la­tion along with all oth­er brain­teasers.

  17. Aley Lawrence says:

    I can do it eas­i­ly by blur­ring my vision through nar­row­ing my eyes

  18. michelle says:

    it gave me a headache

  19. Bob Beaver says:

    A most inter­est­ing exer­cise, par­tic­u­lar­ly as one is con­scious (aware) that the brain is strug­gling against what the eyes see and what the mouth wants to say. I enjoyed the exer­cise, but then again, being an edu­cat­ed Eng­lish­man my brain always fas­ci­nates me.

  20. Khalil says:

    Well it was to say sec­ond time. I used a trick, I did not see the com­plete words while say­ing, I just con­cen­trate on the col­or of last alpha­bet of the word, did not look the whole word at all, in just sec­ond attmept the result was
