Attention capture is something that captures our attention even when we have no intention of it. For a long time, people thought pop out was what resulted in attention capture. People thought motion, color, and other features would work with attention capture. But, as we saw with the garish early-2000s ads, these are reliably ignorable. It turns out that only two methods really work: (1) an abrupt and extreme change in luminescence and (2) the sudden onset of a new perceptual element, like a tiger coming out of the forest.
