Iluzie optica - Change blindness

Change blindness consta in faptul ca in anumite conditii, din cauza ca nu esti atent, nu observi diferente foarte mari intre doua fotografii.
A large fraction of traffic accidents are of the type "driver looked but failed to see". Here, drivers collide with pedestrians in plain view, with cars directly in front of them (the classic "rear-ender"), and even run into trains. (That's right -- run into trains, not the other way around.) In such cases, information from the world is entering the driver's eyes. But at some point along the way this information is lost, causing the driver to lose connection with reality. They are looking but they are not seeing. What's going on? Our findings indicate that the critical factor is attention: To see an object change, it is necessary to attend to it.
