I probably wouldn't actually consider what you are talking about as "negative punishment." For one thing, punishment makes behavior less likely to occur. So I use it for behaviors I really would like to end - "look, if you jump on the person, she leaves and won't give you cookies" "if you pull on the leash, we go further away from that tree you want to sniff".
It may be a minor extinction burst ("but . . . that always worked before!"). Brilliant Canadian trainer Sue Ailsby calls it the "Hey, Stupid!" moment. "Hey, stupid - did you not see me do that? Here, let me make it bigger for you."
