I use no reward markers a lot.
It's not necessarily a correction, but the dogs learn that it means they are NOT getting rewarded and they should try something else.
Example. I tell Patton to Platz. He half-downs. I wait about 5 seconds. He still isn't all the way into a down, so I say "Nope" and turn away, he'll follow and I reset. I mark with a yes or the clicker when he does it correct and I reward for that and release him.
Some people also use NRM (no reward marker) terms like "uh oh" or "try again" as well.
