#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.

    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!

    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.

  7. Larry says:

    I watched it twice, but I counted 34 passes.

  8. 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!
