What Makes Our Brain So Special?


Before start answering the question straight away, i would like to show a image...

Just look at the image of a baby, it is not a photograph. It is an artwork painted on a canvas..

On looking at this photo, what information do you gain?
Is this image looks mysterious or little unsettling? Many people will agree..

In fact if we take any art of a baby or any art that involves a face, eye is the most prominent feature. But here the artist made the eye almost non-existent. Why??

Because the artist wants us to focus on the prophetic gesture of the child instead of face. In other words, the aim of this portrait is to convey a gesture rather than a beautiful baby face.

Inference: - We always give our attention to the eye of an any portrait. Even though the entire image is in our frame of vision, the attention will always goes to eye. So if there is no eye(as in this case) our attention automatically shifts to the gesture. Remember we are not consciously doing this.

Let us see one more image,

In this image, our first focus of attention is the bowler and the second is batsman and third is the stumps and fourth focus is other things in the scene.

In other words, our brain understands this scene in the following way

1. Shane Warne is celebrating , why celebrating?
2. He took the wicket of Andrew Strauss , How?
3. With a big turning ball pitched way outside off stump and turned to dismantle the stumps..

So other details like the crowd behind the scene and the advertisement board carries very little information so we humans generally will not give attention to them.

Here the first object of attention (bowler) gets the higher priority and there is a shift in the attention after a second to the next object of attraction (batsman) and again a shift to third object(stumps).

The amount of details about each object gets into the brain is proportional to the priority of that particular object..

These are very simple cases, how about a scene with lots of objects and each one carries some information?? how do we respond? how attention shift takes place on a complex scene?
