Pause, evaluate, then act.
Impulse control (inhibitory control) is the ability to pause an automatic response long enough to choose a more deliberate one.
It underlies things like waiting your turn, not blurting out the first thought that comes to mind, and resisting a tempting shortcut in favour of a better long-term choice.
This is one of the more well-established areas of difference in ADHD research — the automatic "pause" step can be shorter or less reliable, which isn't a character flaw, it's a difference in how the brain's braking system engages.
Meaning to just check one notification, then noticing twenty minutes later that you never came back to what you were doing.
