It is always interesting to see examples on how our minds work and how easy it is to link this behavior to our development and evolution in a logic way.

I believe that there is much truth to the saying: “The more you learn, the more you realize how little you know”
By getting educated you realize both how much knowledge there is in the world and how complex the world is. You realize that if you get a new idea or a theory, it is extremely likely that somebody have got the same idea before you and already tested it. If you never heard of the idea or theory before, it is extremely likely that it was false. Therefore you get in some way also skeptical when other people have ideas. I think therefore that it is not a coincident that skepticism increases with level of education.

Consider the question, “Why, given the fact that human beings have so much potential, so much intelligence… our cultures are so amazingly diverse and creative and our technology so advanced… Why are we committing species suicide by destroying the habitability of our planet?

Shermer’s lucid and highly relevant talk, using the powerful tool of scientific method as a means of examining the characteristics of our own mind and brain, give us a verifiable and objective answer to this question.

That answer is that human awareness is flawed and has become dysfunctional in the modern era. Sherner clearly delineates the nature of those flaws. Once we are aware of this, we can take action to ameliorate the destructive impact of those flaws in our awareness. This is liberation and freedom from ancient bondages and a small chance for our species to pull out of our nosedive before we drill a big hole.

We’re predisposed, as pattern-seeking mammals, to find “causes” for things we can’t explain.This is why we’re all so riveted by stories of any kind – movies, TV shows, novels, theater. These big brains of ours love explication and resolution.

We are a pattern seeking species. Through our ability to differentiate similar from dissimilar, we are able to produce complex environments like blogs for example. The language we use on blogs is a complex pattern of symbols, shapes, and sounds which we are able to make sense of through the processes of similar and dissimilar – the processes of visual and auditory discrimination.

If we think back to out tribal ancestors, this ability to form visual and auditory patterns of recognition would have been a survival advantage. Not only would it have helped mankind to be able to progress to more and more complex technological and cultural concepts – but it would have enabled many of our ancestors to survive, literally.

Not only are we pattern seeking animals, we are a species which is honed evolutionary for physical survival. The ancestor who was in the forest at night and saw a shape in the woods with which he/she was unfamiliar, would have probably quickly visually processed if the shape was friend or foe. If the shape could not be quickly identified as a friend, or as something harmless, it would have been advantageous from a survival point of view to assume that the shape was harmful. And as the natural world was distinctly more harmful to human survival than it is now for many of us – the wary individual would have been one who assumed harm.

Eye tracking is the process of measuring either the point of gaze (”where we are looking”) or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movements.

The most widely used current designs are video-based eye trackers. A camera focuses on one or both eyes and records their movement as the viewer looks at some kind of stimulus. Most modern eye-trackers use contrast to locate the center of the pupil and use infrared and near-infrared non-collimated light to create a corneal reflection (CR).

Since 2005 Eye tracking is used in Communication systems for disabled allowing the user to speak, mail, surf the web and so with only the eyes as tool. Eye control works even when the user has involuntary movement as a result of CP or other disability, those who wear glasses or many other characteristics that limit the effectiveness of older eye control systems.
