Reading Minds?

Recently I read an article in Scientific American about how we predetermine what we are going to hear or read based on the contexts and beginning sounds of the word. After pondering over this article for a few days it occurred to me that this may also be the same mental process that allows us to read sentences even if the words themselves are scrambled in the middle. What our brains do is go through thousands of possibilities of what we will hear before we have heard the complete word and fills on the blanks, the reason I thought this may be a similar reasoning process so that when we are reading a sentence with scrambled words we subconsciously read the word only by the first and last letters and rule out all words that do not have those first and last letters or fit the context of the text. Our reasoning abilities are astounding with conscious thought but what are truly astounding are our subconscious abilities.
This article also made me wonder if we are able to rule out possibilities based on personal trends, for example if you know a person really well can you predict more closely what they are going to say. If that is true then it may be why close friends and loved ones often finish each other’s sentences unintentionally. On some occasions could it be possible to replace our need to hear the first part of the word with our knowledge of our friends speaking habits? I have noticed that with people I know closely I can finish their sentences how they are going to do so even if the context of the word does not fit which leads me to believe it is a definite possibility. Finally could our ability to preprocess sentences also be used unconsciously in situations and possibly explain the phenomenon of Déjà vu?
