What this video covers
Habituation is the way a repeated, unchanging signal gradually stops registering. The first time something appears you notice it; by the tenth identical time your brain has learned it carries nothing new and quietly tunes it out - which is great for ignoring noise, and a problem when the thing you've learned to ignore is your warning.
The first banner stopped you; by the fifth identical one you were dismissing it without reading - your brain had filed it as "nothing new". That's habituation. It's exactly why over-used warnings and constant confirmations go unseen: people learn the signal is safe to ignore, so the one time it matters, it's already invisible. Change it, or save it, to win attention back.
