Here's an entertaining info for the human mind..
Basically, the concept is top-down versus bottom-up processing. With bottom-up, you start with the core elements, while with top-down, you look for order. For instance, when you look at a dog, you generally don't say to yourself, "Well I see four legs, two eyes, a nose, a mouth, etc, etc..." you immediately say and think "That's a dog," because the majority of humanity searches for order first, rather than sorting through the elements. Well, this is where this particularly get interesting.

This is an instance of top-down processing within the mind. Instead of finding a jumble, we figure out the words almost instinctively because our brains search for order in the letters rather than the words, so as long as the first and last letter in a word remain in place, the rest can be jumbled, and our minds fill in the insanity for us. A healthy human brain actively seeks order as opposed to the elements. If you absolutely can't read the jumbles, you're experience bottom-up processing, whereby you see the letters, and that's it.
Anyways, I thought this was nifty cool, and was wondering if any of you had ever heard or seen of this before?
