While a man provided directions to a construction worker, two experimenters rudely interrupted by passing between them carrying
a door. The man's failure to notice that during this interruption the construction worker was replaced by another person wearing different-colored clothes illustrates:________. A) the popout phenomenon.

A study that is known as the "door study" was conducted by exposing someone to major visual changes. Participants would be regular people giving instructions to a man. While they talked, two other men walked between them carrying a door. The man who had asked for directions would be replaced by a different man, but the change would go unnoticed by the participants in approximately 50% of the times. That phenomenon is called change blindness, and it usually takes place when a person's attention is not focused on visual details.
One reason historians can rely on government records for accurate historical information is because the information presented in government records has been verified by those who collect it.
