intentional blindness

via boingboing:

this telegraph article discusses research on intentional blindness: a phenomenon characterized by not sensing something that is obviously there. interesting stuff. i read another article a while ago on the opposite phenomenon, where missing parts of scenes were inferred, such as people 'seeing' a normal picture of an airplane landing when in fact the picture had a part of the fuselage cropped out.

if you want to check your own puny brains out, follow the link at the bottom of the article to the collection of videos used for testing this phenomenon. have a friend read the purpose for each video and then have them show you the video -- providing you with any prompting if necessary.
