Our vision is selective. And our brain is too. Few months ago on PBS TV channel in my country was documentary film about vision. In one sequence about 30 people was asked to watch big TV screen. On screen were 2 groups of basketball players. Each group had 3 member. One group was dressed in yellow outfit and other was dressed in black. People who wached was asked to count how much will member of yellow dressed group pass the ball to each other. Yellow and black were mixed, not separated. After some time, leader of experiment asked audince are they noticed anything strange. Only two persons of 30 confirmaed there was something strange. Then leaer of experiment rewoud tape and now adked people to look what happens generally on TV screen, not to concentrate on anything specific. And he played same scene again. At one moment, man dressed in monkey costume appears, stayed in middle of TV screen, and even beated his chests, like we see gorillas do. And that lasted 5 seconds, maybe more. Only 2 person of 30 people noticed it in first place, without warning. I think I still have tape of that exeriment somewhere, narrator of documentary told during the film to tape it and to check for ourselves. I don't think there was cheating. And after rewounding and watching same film again I noticed that monkey dressed man atleast 5 or 6 times during the film. And only after narrator inform at the end of the movie to wach it again. Som our vision is selective, ans we have much less capable brains than we like to think...
