Instead of the simplistic five senses of Aristotle: sight, hearing, taste, touch, and smell, there are at least thirty-seven known, differentiated sensory inputs into the brain. All of the information picked by these senses is sent to the brain and absorbed by the subconsciousness, however, only very concrete and relevant data is passed to the conscious mind after it has been processed and reduced. All the rest remains ignored. A good example of this is the Cocktail Party Effect: You can talk with a friend in a crowded party and still listen and understand what he says even if the place is very noisy. You can simultaneously ignore what another nearby person is saying, but if someone over the other side of the room suddenly mentions your name, you notice that sound and respond to it immediately. Not only that your name immediately triggers your attention, you usually are aware of the entire sentence it has came in. From this experience we can learn that our brain records everything that takes place around us. Interesting that certain words like sex, blood, death and kill and such have the same effect in triggering your attention as your name.
