I have over the last year been studying the human mind and many of it’s components as you may well remember interweb.
I have in particular been studying the conscious and unconscious mind and the manner in which it can be manipulated. I find it fascinating but if you don’t please switch off now.
A good example of this is the 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 come 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, FUCK and such have the same effect in triggering your attention as your name.
So, only the information considered as "relevant" goes to the consciousness. Non essential information, short or vague stimuli are stored in the subconscious without reaching our awareness.
Important to stress that they are NOT discarded, but stored EVERYTHING you have ever experienced in your life, from every stranger's face you have ever glanced at in a crowd to every spider web you gazed at as a child, can be retrieved from your memory by hypnosis or by electrical stimulation of the brain cells in temporal lobes. Hence whatever was subliminally put into your brain will stay there forever and in the right circumstances will trigger the right reaction in you.
That is not being said that subliminal messages determine your reaction in an inexorable manner. The accepted opinion is that subliminal messages rather strengthen, accelerate and reinforce reactions in persons who are ALREADY PREDISPOSED to the subject of the message. But I guess you can't be sure.
Now if that wasn’t drivel enough here is some more, The greatest mystery is not that we have been flung at random between the profusion of matter and of the stars, but that within this prison we can draw from ourselves images powerful enough to deny our nothingness, and inanimate objects are classified scientifically into three major categories - those that don't work, those that break down and those that get lost.
