Count basketball passes and man in gorilla suit walks by. 50% of observers didn"t noice the gorilla: change blindness. Involves a failure to detect changes in an object. Ex. coninuity errors in movies: change blindness blindness. Individuals" exaggerated belief that they can detect visual changes and so avoid change blindness. Direct evidence that we are oten widely opimisic about the our own observaional powers. We generally think we are processing the enire visual scene reasonably thoroughly and so can detect visual changes. Greater when they appear to detect object changes rapidly and efortlessly rather than slowly and eforfully. Stronger when people are lead to believe they have previously been very successful in detecing changes. Expectaions: memory for events is oten inluenced by our expectaions, conirmaion bias.
