The human auditory system (     ). A psychologist named Richard Warren demonstrated this particularly well. He recorded a sentence and cut out a piece of the sentence from the recording tape. He replaced the missing piece with a burst of static of the same duration. Nearly everyone who heard the altered recording could report that they heard both a sentence and static. But a majority of people could not tell where the static was! The auditory system had filled in the missing speech information, so that the sentence seemed uninterrupted. Most people reported that there was static and that it existed apart from the spoken sentence. The static and the sentence formed separate perceptual streams due to differences in the quality of sound that caused them to group separately. * static: 잡음(雜音)
