You know our eyelids blink but less know is that so does the human brain, dropping a few frames of visual information here and there.
Those lapses of attention come fast -- maybe just once every tenth of a second. But some people may be missing more than others, according to psychologists at the University of Wisconsin-Madison.
"Intuitively we have this sense that we're viewing the world in a continuous stream, constantly taking in the same amount of information," says Jason Samaha, a University of Wisconsin-Madison doctoral student in psychology. "So if I told people that every 100 milliseconds their brains were taking a bit of a break, I think that would surprise a lot of them."
