Now You See It, Now You Don't

The part of the brain called the parietal cortex, the area responsible for concentration, is also

critical to our ability to detect changes. The exact critical spot lies just a few centimeters above

and behind the right ear – the area many people scratch when concentrating.

We have always known that the parietal cortex was responsible for concentrating. But it was a

surprise to find out it is also important for detecting visual changes in a scene. The finding that

this region of the brain has both these functions, concentration and visual awareness, explains

why we can be so easily deceived by, say, a magicians' trick. When we're concentrating so hard

on something that our processing capacity is at its limits, the parietal cortex is not available to

pay attention to new things and even dramatic changes can go unnoticed. If you're

concentrating on what the magician's left hand is doing, you won't notice what the right hand is

doing."

so...don't concentrate on what the magician is doing &next time I'll concentrate on the other

hand...
