When expected information is missing or marginal the mind can subconsciously dub it in. It seems to use something like a
maximum-likelihood decoder, drawing on a person's past experience. Have you ever turned on a radio during a newscast and it
comes up in the middle of a word? Sometimes you will actually "hear" the whole word and it makes perfect sense, but later you
find out it must have been something else! This can happen when skimming over a newspaper headline - you might "see" a complete
word in your mind (the missing portion even appearing in the same type font) but it later turns out to have been a different
word. If you're on the lookout for this phenomenon you'll spot it in many situations. Possibly the same mechanism is at work
when we are asleep and dreaming: the content has to come from somewhere.
Perception is based largely on expectation.
