*SPOILER ALERT*





I only noticed 2 of the changes -- the backdrop and the woman's shirt.

At ICTCM Boston earlier this year, coworker Sara D. saw a similar video as part of a presentation on perception. In that video, though, there were people tossing basketballs to one another and a gorilla wanders right through the scene, waves at the camera, and then wanders off. Most of the people in the audience did not see the gorilla, because they were told to look for something else.

I'm not surprised. I noticed NOTHING, much to my chagrin.

I didn't notice anything, either. I have no sound on my computer, so I was paying very close attention to the card trick, trying to figure out if I knew what was going on without the sound. But I probably wouldn't have noticed anything even with the sound. I have a very hard time noticing or remembering color.

I picked up on 3 the back drop the woman's shirt and the tablecloth.

I missed the guy's shirt.

The woman's shirt change jumped out at me and the I followed from there.

Yeah, at first I was staring at the woman's new green shirt thinking "WTF?" and then I realized it had changed. But I only noticed the backdrop after that.

The only thing I missed was the man's shirt - probably because it switched from kind of a dull beige color to an equally dull black. Granted the tablecloth color change was dull too, but it was harder to ignore since so much of the action took place on the table.

Strangely, however, the color change made me paranoid about other details too, and I began to think the woman had changed her hair, too.
