“In class we learned that when the brain is overstimulated, it fills in gaps for you. So, say you pass a red hexagonal sign on the road, and someone asks you what words were on it. You’d say ‘STOP.’ And you’d imagine that you saw it. You’d be able to picture that stop sign the way it should have been. That is, of course, if you were properly distracted and didn’t notice an obviously blank sign. This thing distracts us. Somehow it makes our brains fill in blanks with previous experiences, the things we think we should be seeing.”
