On Looking de Alexandra Horowitz

It is much easier to follow the details of a topic when one knows the least bit about it. When that least-bit develops into a great pond of knowledge, one may rightly call oneself an “expert” -and have the brain to prove it. Expertise changes what you see and hear, and it even changes what you can attend to. Neuro-imagery shows us how expert and naive brains look when attending: fundamentally different. Watch the brains of dancers while they watch a dance performance, and you will see considerably more activity than you would find in the brains of nondancers. Expertise leads to the ability to acquire more expertise.
