Mireille and Adam discuss the mechanism of attention as an allocation of one’s resources. If we can think of attention as that of a lens, we can practice choosing what we give our attention to recognizing that multiple things, both externally and internally, routinely compete for our attention. Distraction can also be useful when we utilize it intentionally to manage the focus of our attention.
Attention is the mechanism through which the brain focuses resources on some thing. If you can direct your attention, then you can direct where your brain puts its resources. You can think of attention similar to that of a camera lens. What lens and at what focal length are you using to focus with?
