Closure

Have you ever seen an image or object that is not complete but your brain automatically fills in the parts of the image that are missing and you just assume that those missing parts are there even though they aren't really? Your brain is programmed to perceive those missing parts as being there because of something called closure. Closure is the filling in of gaps present in what you are sensing, usually through vision and assuming that filling in those gaps will complete the object.

An example of closure would be if you were reading and one of the letters comprising a word was partially or completely omitted; your brain would automatically complete the letter to make the word readable.

Being able to read the words on the picture below is the skill of closure. Your brain subconciously fills in the missing letters to make sense of the phrase.
