Study uncovers details of information processing in the brain
New research shows that when we're paying attention to something, that information is processed in a continuous manner. But when we're trying to ignore something, we perceive and experience information in waves or frames, like scenes in a movie. We are better at prioritizing certain times when we are not attending to that space in the world. research shows that the two processes for attending to space and attending to time interact with one another.
