Don't Just Angle Your Eyeball, 'Angle' Your Attention

You can point your eyes towards one object or another. You can diverge or converge your eyes like a focusing dial on a telescope. Those are both hardware issues. But it isn't just the direction of your hardware bits that you can coordinate: you also have choice about where and how you pay attention. And that literally changes the picture. We take it for granted that we can control or at least influence where our eyeballs angle, but we don't often think about how we influence our brain's visual processors to change their priorities when they process the data.
