colour changing card trick

Sarah's shirt change is more noticeable than the others (to me, at least) because it's the only change from a one-color item to a two-toned one, with the collar being different from the rest of the shirt. The other changes, from one-color items to one-color items, don't resonate because while the colors change, the pattern of the objects remains uniform.

I noticed her shirt changed color, that's about it.

amazing, how well our brain can filter out these unimportant changes - this is not a bug, it's a feature! :)

Why is there a gorilla?

Reference to another psychology experiment, where people are asked to count the number of times something happens, or the number of people in a video - I can't remember what, sorry. Afterwards, they're asked if they noticed the guy in a gorilla suit walking through the middle of the scene.

that was actually vary cool,

at 1:00-1:04 u can hear the background is changing...

false. While the woman/Sarah is showing her card at the camera, the camera zooms in on her, leaving the old guy left out, giving him a chance to switch decks. He shows the deck on the side where it has the numbers/suites w/e, then when he spreads it out it turns out Sarah's card is the only red card. Also, that noise is only the snapping noise the guy makes, but the camera didn't zoom out on the guy it zoomed in on the card

0/4... This is good

i noticed the girls clothes change.
