[Slasher Movies] Why do people run away from the killer after briefly knocking them out?

Slasher movies have this trope wherein the killer gets knocked out momentarily, and their victims just run away. Why not end it there? Stomp on their face a few times, put that adrenaline to good use. 

I think the only time I've seen somebody take the opportunity was in Scream 3, when Patrick Warbuton beat the tar out of Ghostface before dying to the knife that was already lodged in his back.

You're right. The monkey reflex is to just keep hitting until the target is no longer a threat. (It's one reason self-defense with a knife is so problematic.) The best explanation in this case is that slasher-movie villains pick their prey really well. The victims are so skittish they run even when they have an advantage.
