#2. Classic attention experiment (1-minute video)

Let’s try this fun experiment, conceived by Simons and Chabris for their classic study on sustained inattentional blindness.

–>You will watch a brief video clip, and your challenge is to count how many times that the players wearing white pass the basketball.

    I counted 27, plus 1 gorilla.

  2. Susie says:

    The first time I watched I counted 30 passes,saw the gorilla & the S’s, but didn’t notice the white/white and black/black passing combinations. I’m thinking that it’s because I’ve been an elementary teacher for 20 years. For example, I’ve had to train myself to watch all of my children on the playground at the same time, though they may be doing different activities. I have to conduct a small reading group, while monitoring the computer station, the independent workers, etc. to make sure that everyone is on task while interacting with the reading group as well as taking mental notes to write down informal assessment grades for each child in the reading group between that group and the next.

  3. Susie says:

    I watched it a second time, focusing on the white shirts passing to white shirts and got 15. The third time I focused on black shirts passing to black shirts and counted 20, though I wasn’t quite sure because it looked as though the ball had been passed off out of view a couple of times. The second and third time I did notice the gorilla, but I didn’t notice the S’s, even though I had noticed them the first time I watched.

  4. kayare says:

    i counted 28 but the gorilla got in the way then i lost count.. so how many passes are there??

  5. nick says:

    I only counted 29 and I saw the monkey the first the only reason I watched it twice more is because some ppl were saying 30 + times I counted 29 three times

  6. nick says:

    My bad 33 passes and the monkey and blacks pass 2 black and white pass to white…….and they pass in a sequence they only pass to the same person each time

  7. Hameed says:

    I see 14 times ball changed hands between white dress group and 18 times among black dress group…

  8. LaLaLa2012 says:

    I didn’t see the gorilla you guys are talking about. Or the flying pig…

  9. ardit says:

    32 I didn’t see any gorilla.

  10. Kimmie says:

    I seen two teams of three, two balls and one gorilla. Between the two teams I counted 33 passes.

  11. benedict says:

    the visual noise was very distracting, its futile to count the passes… no I did not see the gorilla the first time…

  12. chris says:

    well, i counted 29 then 24 and saw the gorilla both times.

  13. Muddy says:

    Saw a black thing in the video but was busy in counting passes..thay come out to be 28

  14. Tammy says:

    i counted 29

  15. hailrasec says:

    29

  16. i dunno says:

    This is pretty interesting. I did see the gorilla, and counted only 27 passes. There were a few ‘fake” passes. Does anybody know the correct #? The study on the stranger asking directions, and changing as the door passed is very interesting. Great website. Glad to find it!

  17. kirsti says:

    haha seriously didn’t see the gorilla until i read someone had seem him. i was only focused on the balls. counted 29-30 i think.

  18. Denis says:

    haha i counted 29 times, i saw the gorilla but did not process the idea that he walked in

  19. terry woodruff says:

    i counted 31 passes , there may have been more but the dam gorilla got in the way.

  20. Seanathan McAndrew says:

    Saw this in class last week. It totally got me.

  21. johnny says:

    I counted 34, 1 gorilla, and noticed that the white shirt team and black shirt team don’t pass each other the basketball but rather they keep one ball between the white shirts and one between the black shirts.

  22. Larry says:

    I watched it twice, but I counted 34 passes.

  23. Crystal says:

    I counted 30 times, and noticed someone go through the group, but DID NOT notice it was a gorilla. After reading the posts and going back to watch it, I was amazed at how it stopped to pound it’s chest and slowly and deliberately it was moving. I didn’t notice but a moving shape!
